RestSharp - WP7 - Cannot deserialize XML to a list - windows-phone-7

I use RestSharp in my Windows Phone 7.1 project.
I have a response in XML format here:
https://skydrive.live.com/redir.aspx?cid=0b39f4fbbb0489dd&resid=B39F4FBBB0489DD!139&parid=B39F4FBBB0489DD!103&authkey=!AOdT-FiS6Mw8v5Y
I tried to deserialize that response to a class:
public class fullWall
{
public _user user { get; set; }
public int numberOfFriend { get; set; }
public int numberOfPhoto { get; set; }
public List<timhotPhotos> timhotPhotos { get; set; }
public fullWall()
{
timhotPhotos = new List<timhotPhotos>();
}
}
All properties are ok except the timhotPhotos list, as you can see here:
timhotPhotos class:
public class timhotPhotos
{
public string id { get; set; }
public string title { get; set; }
public string description { get; set; }
public string url { get; set; }
public double width { get; set; }
public double height { get; set; }
public DateTime createdDate { get; set; }
public _user user { get; set; }
public int numOfComment { get; set; }
public int numOfRate { get; set; }
public int numOfView { get; set; }
public bool rated { get; set; }
}
Where am I wrong?

You'll have to change the default XML deserializer to the DotNetXmlDeserializer, like this:
RestClient client;
client.AddHandler("application/xml", new DotNetXmlDeserializer());
Then, add the XmlElement attribute to the List<timhotPhotos> timhotPhotos property like this:
public class fullWall
{
public _user user { get; set; }
public int numberOfFriend { get; set; }
public int numberOfPhoto { get; set; }
[System.Xml.Serialization.XmlElement()]
public List<timhotPhotos> timhotPhotos { get; set; }
public fullWall()
{
timhotPhotos = new List<timhotPhotos>();
}
}
Now it should work fine!

Web API JSON deserialization converting value issue

I am trying to insert JSON data into my models via EF 6. I am getting this error;
Inner Exception is {0}System.ArgumentException: Could not cast or convert from System.String to EPINMiddleWareAPI.Models.Serial.
konum: Newtonsoft.Json.Utilities.ConvertUtils.EnsureTypeAssignable(Object value, Type initialType, Type targetType)

Here is my model structure:
public class ConfirmResponse
{
public int Id { get; set; }
public string referenceId { get; set; }
public string version { get; set; }
public string signature { get; set; }
public string paymentID { get; set; }
public string productCode { get; set; }
public string currency { get; set; }
public string ApplicationCode { get; set; }
public double unitPrice { get; set; }
public double totalPrice { get; set; }
public string purchaseStatusCode { get; set; }
public DateTime? purchaseStatusDate { get; set; }
public DateTime? requestDateTime { get; set; } = DateTime.Now;
public string merchantProductCode { get; set; }
public List<Coupon> coupons { get; set; }
}
public class Coupon
{
public int Id { get; set; }
public int ConfirmResponseID { get; set; }
public List<Serial> serials { get; set; }
public List<Pin> pins { get; set; }
public virtual ConfirmResponse confirmResponse { get; set; }
}
public class Serial
{
public int Id { get; set; }
public string serials { get; set; }
public int CouponID { get; set; }
public virtual Coupon coupons { get; set; }
}
My sample JSON:
"{\"referenceId\":\"0000000046\",\"paymentId\":\"MDO1037624\",\"productCode\":\"001002461285\",\"quantity\":\"1\",\"currency\":\"TL\",\"unitPrice\":\"46,47\",\"totalPrice\":\"46,47\",\"merchantProductCode\":\"\",\"purchaseStatusCode\":\"00\",\"purchaseStatusDate\":\"2019-03-17T20:58:48Z\",\"coupons\":[{\"serials\":[\"c57a55b5-b2d4-46e7-86e0-cc13726ca8a7\"],\"pins\":[\"T6VC-XC6X-3H6JS-NVWL-93PCa\"]}],\"version\":\"V1\",\"signature\":\"2f961c7dbc32c3bc128b6e69d19e8e1a\",\"applicationCode\":\"52e7cf966b724749a7c4efadc3727ed7\"}"
How can I fix this problem? I would like to insert this JSON into my database tables. I am using EF 6.
edit:
This model structure solved my problem. Now I can insert serials and pins into database.
public class ConfirmResponse
{
public int Id { get; set; }
public string referenceId { get; set; }
public string version { get; set; }
public string signature { get; set; }
public string paymentID { get; set; }
public string productCode { get; set; }
public string currency { get; set; }
public string ApplicationCode { get; set; }
public double unitPrice { get; set; }
public double totalPrice { get; set; }
public string purchaseStatusCode { get; set; }
public DateTime? purchaseStatusDate { get; set; }
public DateTime? requestDateTime { get; set; } = DateTime.Now;
public string merchantProductCode { get; set; }
public List<Coupon> coupons { get; set; }
}
public class Coupon
{
public int Id { get; set; }
public int ConfirmResponseID { get; set; }
public List<string> serials { get; set; }
public List<string> pins { get; set; }
public virtual ConfirmResponse confirmResponse { get; set; }
public List<string> StringsSerial
{
get { return serials; }
set { serials = value; }
}
public List<string> StringsPin
{
get { return pins; }
set { pins = value; }
}
[Required]
public string Serial
{
get { return String.Join(",", serials); }
set { serials = value.Split(',').ToList(); }
}
[Required]
public string Pin
{
get { return String.Join(",", pins); }
set { pins = value.Split(',').ToList(); }
}
}
Thanks in advance.
you're json is wrong
take a look into the coupons array, you initialize the serials array with an string/guid and not with a model of serial
it should be
"coupons": [{
{
"serials": [{
"serials": "c57a55b5-b2d4-46e7-86e0-cc13726ca8a7"
}
],
}
}
]...
I guess for Pins the same

Why is Entity Framework navigation property null?

I am use code first model with a relationship below
public class ApplicationUser : IdentityUser
{
public string UserFirstName { get; set; }
public string UserLastName { get; set; }
public string UserSchool { get; set; }
public UserProfileData UserProfileData { get; set; }
public int? MedicalSpecialtyId { get; set; }
public virtual MedicalSpecialty MedicalSpecialty { get; set; }
// public int? AnalyticsDataId { get; set; }
// public ICollection<AnalyticsData> AnalyticsDatas { get; set; }
}
public class MedicalSpecialty
{
public int Id { get; set; }
public string Description { get; set; }
// public int ApplicationUserId { get; set; }
public virtual ApplicationUser ApplicationUser { get; set; }
public ICollection<ProgramDetailData> ProgramDetailDatas { get; set; }
}
And when I try to get a User's associated MedicalSpecialty object it is NULL
userSpecialtyName = currentUser.MedicalSpecialty.Description;
BUT when I run this code above it the currentUser.MedicalSpecialty is no longer NULL. What happened?? Somehow that LINQ query woke up the object and filled it with data
var userSpecialtyId = currentUser.MedicalSpecialtyId;
userSpecialtyName = _medicalSpecialtyRepository.Find
(x => x.Id == userSpecialtyId).FirstOrDefault().Description;
userSpecialtyName = currentUser.MedicalSpecialty.Description;

Xamarin - reading JSON file and reading the values

everyone ! I'm new in Xamarin. I've this json file...
{
"debug":true,
"sequence":[
"p1"
],
"pages":[
{
"pageId":"p1",
"type":"seq",
"elements":[
{
"type":"smallVideo",
"width":300,
"height":300,
"top":0,
"left":0,
"file":"xxx.mp4"
}
]
}
],
"index":[
{
"width":300,
"height":300,
"top":0,
"left":0,
"goTo":"p1"
}
]
}
And this is my simple code...
using Newtonsoft.Json;
JObject elements = JObject.Parse(File.ReadAllText("elements.json"));
Console.WriteLine(elements);
Ok, I can see on my output screen the whole JSON file. Fine...
But I'd like to read any value just like javascript, examples...
elements.debug (true)
elements.pages[0].pageId
So, I need to retrieve values based on the key/path like it's usual in Javascript. Any clue ?
ty !
C# is a little bit different from js, here you need to declare objects.
In your case you need to create new class called ElementsObj and your object would be this class instance:
public class ElementsObj
{
public bool debug { get; set; }
public List<string> sequence { get; set; }
public List<Page> pages { get; set; }
public List<Index> index { get; set; }
}
public class Element
{
public string type { get; set; }
public int width { get; set; }
public int height { get; set; }
public int top { get; set; }
public int left { get; set; }
public string file { get; set; }
}
public class Page
{
public string pageId { get; set; }
public string type { get; set; }
public List<Element> elements { get; set; }
}
public class Index
{
public int width { get; set; }
public int height { get; set; }
public int top { get; set; }
public int left { get; set; }
public string goTo { get; set; }
}
In future use http://json2csharp.com/ to generate classes from JSON file.
Later you can deserialize your JSON to this object.
I'd suggest Newtonsoft lib to do this:
ElementsObj tmp = JsonConvert.DeserializeObject<ElementsObj>(jsonString);
1) Option create an object that reflects your JSON structure:
public class Element
{
public string type { get; set; }
public int width { get; set; }
public int height { get; set; }
public int top { get; set; }
public int left { get; set; }
public string file { get; set; }
}
public class Page
{
public string pageId { get; set; }
public string type { get; set; }
public List<Element> elements { get; set; }
}
public class Index
{
public int width { get; set; }
public int height { get; set; }
public int top { get; set; }
public int left { get; set; }
public string goTo { get; set; }
}
public class MyObject
{
public bool debug { get; set; }
public List<string> sequence { get; set; }
public List<Page> pages { get; set; }
public List<Index> index { get; set; }
}
MyObject parsed = JsonConvert.DeserializeObject<MyObject>(File.ReadAllText("elements.json"));
var debug = parsed.debug;
2) Option using dynamic
dynamic results = JsonConvert.DeserializeObject<dynamic>(File.ReadAllText("elements.json"));
var debug = dynamic.debug;

Microsoft Cognitive Services Web Search API - DeSerialization Issues

I want to learn Cognitive Services Web Search APIs so I started creating a bot application . I already have a account sub- key and other required information also I read many articles and watch build 2016 videos on this as well.I am having trouble while deserializing the result .
I am not able to find the proxy class that I can use to do that .
The url I am using is https://api.cognitive.microsoft.com/bing/v5.0/search/
and I found a proxy class for previous api version . Can anybody tell me how to get proxy class of the api request / response in VS 2015 for these service.
My Code look like this:
string BingSearchUrl = "https://api.cognitive.microsoft.com/bing/v5.0/search/";
const string bingKey = "Key";
public static async Task<string> Search(string query)
{
var client = HttpClientFactory.Create();
var queryString = BingSearchUrl + "?q=" + query + "&count=10";
// Request headers
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", bingKey);
client.DefaultRequestHeaders.Add("Accept", "application/json");
// Request parameters
string r = await client.GetStringAsync(queryString);
var jsonResult = JsonConvert.DeserializeObject<Bing.ExpandableSearchResult>(r);
return jsonResult.Web.First().Title;
Try below code
public string BingSearchUrl = "https://api.cognitive.microsoft.com/bing/v5.0/search/";
const string bingKey =[KEY];
public async void Search()
{
var client = new HttpClient();
var queryString = HttpUtility.ParseQueryString(string.Empty);
// Request headers
client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", bingKey);
// Request parameters
queryString["q"] = "microsoft";
queryString["count"] = "10";
queryString["offset"] = "0";
queryString["mkt"] = "en-us";
queryString["safeSearch"] = "Moderate";
var uri = "https://api.cognitive.microsoft.com/bing/v5.0/news/search?" + queryString;
var response = await client.GetStringAsync(uri);
var jsonResult = JsonConvert.DeserializeObject<BingJson>(response);
string title = jsonResult.value[0].name.ToString();
}
With the jsonResult.value[0] you can loop through the results. First results is at [0] position.
I Created a model class looking at the bing search response json. It looks like,
public class BingJson
{
public string _type { get; set; }
public Instrumentation instrumentation { get; set; }
public string readLink { get; set; }
public int totalEstimatedMatches { get; set; }
public Value[] value { get; set; }
}
public class Instrumentation
{
public string pingUrlBase { get; set; }
public string pageLoadPingUrl { get; set; }
}
public class Value
{
public string name { get; set; }
public string url { get; set; }
public string urlPingSuffix { get; set; }
public Image image { get; set; }
public string description { get; set; }
public About[] about { get; set; }
public Provider[] provider { get; set; }
public DateTime datePublished { get; set; }
public string category { get; set; }
}
public class Image
{
public Thumbnail thumbnail { get; set; }
}
public class Thumbnail
{
public string contentUrl { get; set; }
public int width { get; set; }
public int height { get; set; }
}
public class About
{
public string readLink { get; set; }
public string name { get; set; }
}
public class Provider
{
public string _type { get; set; }
public string name { get; set; }
}
With this model, I am able to get the desired result. The Model which is presented in the other answer is not working in my case.
namespace BingSearchBot
{
public class RootObject
{
public string _type { get; set; }
public WebPages webPages { get; set; }
public RelatedSearches relatedSearches { get; set; }
public RankingResponse rankingResponse { get; set; }
}
public class WebPages
{
public string webSearchUrl { get; set; }
public int totalEstimatedMatches { get; set; }
public List<Value> value { get; set; }
}
public class Value
{
public string id { get; set; }
public string name { get; set; }
public string url { get; set; }
public List<About> about { get; set; }
public string displayUrl { get; set; }
public string snippet { get; set; }
public List<DeepLink> deepLinks { get; set; }
public string dateLastCrawled { get; set; }
public List<SearchTag> searchTags { get; set; }
}
public class About
{
public string name { get; set; }
}
public class DeepLink
{
public string name { get; set; }
public string url { get; set; }
public string snippet { get; set; }
}
public class SearchTag
{
public string name { get; set; }
public string content { get; set; }
}
public class Value2
{
public string text { get; set; }
public string displayText { get; set; }
public string webSearchUrl { get; set; }
}
public class RelatedSearches
{
public string id { get; set; }
public List<Value2> value { get; set; }
}
public class Value3
{
public string id { get; set; }
}
public class Item
{
public string answerType { get; set; }
public int resultIndex { get; set; }
public Value3 value { get; set; }
}
public class Mainline
{

EF 5 ENUM with Navigation

I'm trying to use Enum support with EF 5 and dot.NET 4.5.
The situation I have is the following.
POCO:
public partial class tbl_pp_Message
{
public tbl_pp_Message()
{
this.tbl_pp_MessageDistribution = new List<tbl_pp_MessageDistribution>();
}
public int MessageId { get; set; }
public string Subject { get; set; }
public string From { get; set; }
public string Body { get; set; }
public int PriorityId { get; set; }
public System.DateTime CreateDate { get; set; }
public int CreateById { get; set; }
[ForeignKey("PriorityId")]
public virtual tbl_pp_MessagePriority tbl_pp_MessagePriority { get; set; }
public virtual ICollection<tbl_pp_MessageDistribution> tbl_pp_MessageDistribution { get; set; }
}
public partial class tbl_pp_MessagePriority
{
public tbl_pp_MessagePriority()
{
this.tbl_pp_Message = new List<tbl_pp_Message>();
}
public int MessagePriorityId { get; set; }
public string Description { get; set; }
public Nullable<int> DisplayOrder { get; set; }
public bool ShowAlert { get; set; }
public virtual ICollection<tbl_pp_Message> tbl_pp_Message { get; set; }
}
With the code listed above NOT using an ENUM the world is happy.
When I try to add an Enum the POCO will look like this.
[Flags]
public enum MessagePriorityEnum : int
{
NONE = 0,
Urgent = 1,
Normal = 2,
Low = 3
}
public partial class tbl_pp_Message
{
public tbl_pp_Message()
{
this.tbl_pp_MessageDistribution = new List<tbl_pp_MessageDistribution>();
}
public int MessageId { get; set; }
public string Subject { get; set; }
public string From { get; set; }
public string Body { get; set; }
public MessagePriorityEnum PriorityId { get; set; }
public System.DateTime CreateDate { get; set; }
public int CreateById { get; set; }
[ForeignKey("PriorityId")]
public virtual tbl_pp_MessagePriority tbl_pp_MessagePriority { get; set; }
public virtual ICollection<tbl_pp_MessageDistribution> tbl_pp_MessageDistribution { get; set; }
}
This will not work during a save because it doesn't like the ForeignKey attribute. This error will be thrown during a save.
Schema specified is not valid. Errors:
(129,6) : error 0112: The types of all properties in the Dependent Role of a referential constraint must be the same as the corresponding property types in the Principal Role. The type of property 'PriorityId' on entity 'tbl_pp_Message' does not match the type of property 'MessagePriorityId' on entity 'tbl_pp_MessagePriority' in the referential constraint 'tbl_pp_MessagePriority_tbl_pp_Message'.
If the navigation for tbl_pp_MessagePriority is removed from tbl_pp_Message POCO. And the navigation removed from tbl_pp_MessagePriority POCO back to tbl_pp_Message then it works.
With out the navigation removed it will generate a SQL statement like this.
insert [dbo].[tbl_pp_Message]
([Subject],
[From],
[Body],
[PriorityId],
[CreateDate],
[CreateById],
[tbl_pp_MessagePriority_MessagePriorityId])
values ('Test ENUM EF Code First 5.0' /* #0 */,
'Daniel.Bivens' /* #1 */,
'Test 01 Enum Body - The Magic Unicorn Edition' /* #2 */,
2 /* #3 */,
'2013-05-23T10:52:09' /* #4 */,
5 /* #5 */,
null)
select [MessageId]
from [dbo].[tbl_pp_Message]
where ##ROWCOUNT > 0
and [MessageId] = scope_identity()
It would be ok if the tbl_pp_MessagePriority_MessagePriorityId was not added to the insert.
What can be done to keep the navigaion in EF code first while using ENUM support? Is there a DataAnnotation or a Mapping API?
Please post any suggestions you may have. This project is not using an EDMX/T4 template.
Working POCO:
public partial class tbl_pp_Message
{
//public tbl_pp_Message()
//{
// this.tbl_pp_MessageDistribution = new List<tbl_pp_MessageDistribution>();
//}
public int MessageId { get; set; }
public string Subject { get; set; }
public string From { get; set; }
public string Body { get; set; }
public MessagePriorityEnum PriorityId { get; set; }
public System.DateTime CreateDate { get; set; }
public int CreateById { get; set; }
//[ForeignKey("PriorityId")]
//public virtual tbl_pp_MessagePriority tbl_pp_MessagePriority { get; set; }
//public virtual ICollection<tbl_pp_MessageDistribution> tbl_pp_MessageDistribution { get; set; }
}
public partial class tbl_pp_MessagePriority
{
//public tbl_pp_MessagePriority()
//{
// this.tbl_pp_Message = new List<tbl_pp_Message>();
//}
public int MessagePriorityId { get; set; }
public string Description { get; set; }
public Nullable<int> DisplayOrder { get; set; }
public bool ShowAlert { get; set; }
//public virtual ICollection<tbl_pp_Message> tbl_pp_Message { get; set; }
}
The working POCO would be ok if no navigation was needed.
The thing I was missing was setting the look-up table primary key to the same ENUM type instead of an int.
Working POCO with ENUM and navigation.
public partial class tbl_pp_Message
{
public tbl_pp_Message()
{
this.tbl_pp_MessageAction = new List<tbl_pp_MessageAction>();
this.tbl_pp_MessageAttachment = new List<tbl_pp_MessageAttachment>();
this.tbl_pp_MessageDistribution = new List<tbl_pp_MessageDistribution>();
}
public int MessageId { get; set; }
public string Subject { get; set; }
public string From { get; set; }
public string Body { get; set; }
public MessageTypeEnum TypeId { get; set; }
public System.DateTime CreateDate { get; set; }
public int CreateById { get; set; }
[ForeignKey("TypeId")]
public virtual tbl_pp_MessageType tbl_pp_MessageType { get; set; }
public virtual ICollection<tbl_pp_MessageAction> tbl_pp_MessageAction { get; set; }
public virtual ICollection<tbl_pp_MessageAttachment> tbl_pp_MessageAttachment { get; set; }
public virtual ICollection<tbl_pp_MessageDistribution> tbl_pp_MessageDistribution { get; set; }
}
public partial class tbl_pp_MessageType
{
public tbl_pp_MessageType()
{
this.tbl_pp_Message = new List<tbl_pp_Message>();
}
[Key]
public MessageTypeEnum MessageTypeId { get; set; }
public string Description { get; set; }
public Nullable<int> DisplayOrder { get; set; }
public bool ShowAlert { get; set; }
public virtual ICollection<tbl_pp_Message> tbl_pp_Message { get; set; }
