My requirement is to compare the values in string with the list of string.
Code:
string Names = "Prabha,Karan";
List<string> Presenter = new List<string> { "Prabha", "Joe", "Hukm" };
bool Presented = Presenter.Contains(Names.Split(','));
the above code throws an error and here i need to find the names are presented in the presenter(Presenter has the splited values of the Names).
you could do it like below:
var splitNames = Names.Split(',');
bool Presented = Presenter.Any(p => splitNames.Contains(p));
EDIT:
If you're interested what are the matches just do:
var matches = Presenter.Where(p => splitNames.Contains(p))
string names = "Prabha,Karan";
List<string> presenter = new List<string> { "Prabha", "Joe", "Hukm" };
IEnumerable<string> namesList = names.Split(',').Select(x => x.Trim());
var list = presenter.Intersect(namesList);
bool presented = namesList.Count() == list.Count());
The unit tests to cover your case:
[Test]
public void AllSourceEntriesAreFoundInTheTargetList()
{
string names = "Prabha,Karan";
List<string> presenter = new List<string> { "Prabha", "Joe", "Hukm" };
IEnumerable<string> namesList = names.Split(',').Select(x => x.Trim());
var list = presenter.Intersect(namesList);
Assert.AreNotEqual(namesList.Count(), list.Count());
presenter = new List<string> { "Prabha", "Karan", "SomeAnother" };
var list1 = presenter.Intersect(namesList);
Assert.AreEqual(namesList.Count(), list1.Count());
}

***ctx.Load(listItemCollection,
eachItem => eachItem.Include(
item => item,
item => item["Column1"],
item => item["Column2"]
));***
i have list of fields in a array of string instead of column1 and column2, how can i pass it through in include linq, not able to create proper lambda on runtime. i tried following ways but couldn't get success. Static befor loops works but thw fields added in loop fails as it doesn't evaluate string value in loop
***Expression<Func<ListItem, object>>[] paramss = new
Expression<Func<ListItem, object>>[length];
paramss[0] = x => x.ContentType;
paramss[1] = x => x["Title"];
count = 2;
foreach (string item in solConnDefModel.Columns)
{ paramss[count] = x => x[item];
count++;
}***
Please take a reference of below code:
List dlist = context.Web.Lists.GetByTitle("listname");
context.Load(dlist);
context.ExecuteQuery();
string[] fieldNames = { "Id", "Title", "num", "mStartDate" };
// Create the expression used to define the fields to be included
List<Expression<Func<ListItemCollection, object>>> fieldsToBeIncluded = new List<Expression<Func<ListItemCollection, object>>>();
foreach (string s in fieldNames)
{
fieldsToBeIncluded.Add(items => items.Include(item => item[s]));
}
// Initialize the collection of list items
var listItems = dlist.GetItems(new CamlQuery());
context.Load(listItems, fieldsToBeIncluded.ToArray());
context.ExecuteQuery();
You can hover on load method to see what type parameter it requires, then generate a corresponding one and pass it.
i have to create lambda expression at runtime. following code i was able to get expected value
Expression<Func<ListItem, object>>[] paramss = new Expression<Func<ListItem, object>>[length];
foreach (string item in Columns)
{
if (item.ToLower() != "contenttype")
{
ParameterExpression parameter = Expression.Parameter(typeof(ListItem), "x");
var propertyInfo = typeof(ListItem).GetMethod("get_Item");
var arguments = new List<Expression> { Expression.Constant(item) };
var expression = Expression.Call(parameter, propertyInfo, arguments);
var lambda = Expression.Lambda<Func<ListItem, object>>(expression, parameter);
paramss[count] = lambda;
}
else
{
paramss[count] = x => x.ContentType;
}
count++;
}
I have a generic List like
List<return> returnlist
class return
{
public string returnid {get; set;
...
public List<string> Vouchernumbers
}
I bind the returnlist to the telerik radgridview.
How can i bind the voucherlist to the GridviewComboboxcolumn for each row ?
I have bind the voucherlist to the combobox after radgridview_complete_binding.
You need to create the grid with columns and data
You need to add the combobox column, initialize it.. Please check you need to have a dataeditor in here
Assign the string to datasource
comboColumn.DataSource = new String[] { "Test1", "Test2"};
You can bind the collections too:
Binding list BindingList<ComboBoxDataSourceObject> list = new BindingList<ComboBoxDataSourceObject>();
ComboBoxDataSourceObject object1 = new ComboBoxDataSourceObject();
object1.Id = 1;
object1.MyString = "Test 1";
list.Add(object1);
ComboBoxDataSourceObject object2 = new ComboBoxDataSourceObject();
object2.Id = 2;
object2.MyString = "Test 2";
list.Add(object2);
colboCol2.DataSource = list;
radGridView1.Columns.Add(colboCol2);
create radcombobox and set datasource and add it to rad grid
eg :
GridViewComboBoxColumn col = new GridViewComboBoxColumn();
col.DataSource = DAL.ActiveDb.GetList<SalesRep>().ToList().OrderBy(x => x.RepName).Select(x => new { Id = x.Id, x.RepName });
col.DropDownStyle = RadDropDownStyle.DropDown;
col.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
col.DisplayMember = "RepName";
col.ValueMember = "Id";
col.FieldName = "RepId";
col.HeaderText = "Rep Name";
col.Width = 200;
//var t = gridColInfo.Where(x => x.ColumnName.ToLower() == "repid").FirstOrDefault();
//if (t != null)
//{
// col.Width = t.ColumnWidth;
//}
this.radGridBillwiseOpening.Columns.Add(col);
I am using Dynamic Linq helper for grouping data. My code is as follows :
Employee[] empList = new Employee[6];
empList[0] = new Employee() { Name = "CA", State = "A", Department = "xyz" };
empList[1] = new Employee() { Name = "ZP", State = "B", Department = "xyz" };
empList[2] = new Employee() { Name = "AC", State = "B", Department = "xyz" };
empList[3] = new Employee() { Name = "AA", State = "A", Department = "xyz" };
empList[4] = new Employee() { Name = "A2", State = "A", Department = "pqr" };
empList[5] = new Employee() { Name = "BA", State = "B", Department = "pqr" };
var empqueryable = empList.AsQueryable();
var dynamiclinqquery = DynamicQueryable.GroupBy(empqueryable, "new (State, Department)", "it");
How can I get back the Key and corresponding list of grouped items i.e IEnumerable of {Key, List} from dynamiclinqquery ?
I solved the problem by defining a selector that projects the Key as well as Employees List.
var eq = empqueryable.GroupBy("new (State, Department)", "it").Select("new(it.Key as Key, it as Employees)");
var keyEmplist = (from dynamic dat in eq select dat).ToList();
foreach (var group in keyEmplist)
{
var key = group.Key;
var elist = group.Employees;
foreach (var emp in elist)
{
}
}
The GroupBy method should still return something that implements IEnumerable<IGrouping<TKey, TElement>>.
While you might not be able to actually cast it (I'm assuming it's dynamic), you can certainly still make calls on it, like so:
foreach (var group in dynamiclinqquery)
{
// Print out the key.
Console.WriteLine("Key: {0}", group.Key);
// Write the items.
foreach (var item in group)
{
Console.WriteLine("Item: {0}", item);
}
}

for this i have create Poco class and i get Order data using poco class, but i can't get the items array data how can i get items data
Here is my code
public List<Message> PlaceOrder(PlaceOrder order)
{
// List<PlaceOrder> entities = (List<PlaceOrder>)JavaScriptConvert.DeserializeObject(json, typeof(List<PlaceOrder>));
int PayOrderID = 0;
List<Message> Result;
Result = new List<Message>();
try
{
Order objOrder = new Order();
PayHist objPayhis = new PayHist();
objOrder.LocationId = order.LocationId;
objOrder.DeviceIdentifier = order.DeviceIdentifier;

entities.AddObject("Orders", objOrder);
entities.SaveChanges();
int orderId = objOrder.OrderId;

objPayhis.OrderId = orderId;
objPayhis.PayType = order.ShipMethod;
objPayhis.Amount = float.Parse(order.Amount);
entities.AddObject("PayHists", objPayhis);

Message objMessage = new Message();
objMessage.Messagevalue = "Sucess";
Result.Add(objMessage);
return Result;
}
Please help me..
Try this (you need to fix your Json by replacing the "=" signs by ":" signs" before):
[WebInvoke(Method = "POST", UriTemplate = "")]
public HttpResponseMessage Add(JsonValue json) {
JsonValue order = json["order"];
JsonArray items = (JsonArray) order["items"];
JsonValue item1 = items[0];
var notes1 = item1["notes"];
return new HttpResponseMessage(HttpStatusCode.OK);
}
.NET 4, I have
public class Humi
{
public int huKey { get; set; }
public string huVal { get; set; }
}
And in another class is this code in a method:
IEnumerable<Humi> someHumi = new List<Humi>(); //This is actually ISingleResult that comes from a LinqToSql-fronted sproc but I don't think is relevant for my question
var humia = new Humi { huKey = 1 , huVal = "a"};
var humib = new Humi { huKey = 1 , huVal = "b" };
var humic = new Humi { huKey = 2 , huVal = "c" };
var humid = new Humi { huKey = 2 , huVal = "d" };
I want to create a single IDictionary <int,string[]>
with key 1 containing ["a","b"] and key 2 containing ["c","d"]
Can anyone point out a decent way to to that conversion with Linq?
Thanks.
var myDict = someHumi
.GroupBy(h => h.huKey)
.ToDictionary(
g => g.Key,
g => g.ToArray())
Create an IEnumerable<IGrouping<int, Humi>> and then project that into a dictionary. Note .ToDictionary returns a Dictionary, not an IDictionary.
You can use ToLookup() which allows each key to hold multiple values, exactly your scenario (note that each key would hold an IEnumerable<string> of values though not an array):
var myLookup = someHumi.ToLookup(x => x.huKey, x => x.huVal);
foreach (var item in myLookup)
{
Console.WriteLine("{0} contains: {1}", item.Key, string.Join(",", item));
}
Output:
1 contains: a,b
2 contains: c,d
