download files from ftp to local drive - ftp

In FTP Sub Folder contains some csv files want to download into local drive folder within one csv file.
In FTP each csv file contains only one record.So,Now i want get all 5 records into localdrive folder in one csv file.Here is code works only for one csv file.
private void DownloadFile(string userName, string password, string ftpSourceFilePath, string localDestinationFilePath)
{
//FileStream responseStream =null;
int Length = 2048;
Byte[] buffer = new Byte[Length];
// int bytesRead = responseStream.Read(buffer, 0, Length);
int bytesRead = 0;
FtpWebRequest request = CreateFtpWebRequest(ftpSourceFilePath, userName, password, false);
request.Method = WebRequestMethods.Ftp.DownloadFile;
Stream reader = request.GetResponse().GetResponseStream();
FileStream fileStream = new FileStream(localDestinationFilePath, FileMode.Create);
while (true )
{
bytesRead = reader.Read(buffer,0,buffer.Length);
if (bytesRead == 0)
break;
fileStream.Write(buffer, 0, bytesRead);
}
fileStream.Close();
}
private FtpWebRequest CreateFtpWebRequest(string ftpDirectoryPath, string userName, string password, bool keepAlive)
{
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(new Uri(ftpDirectoryPath));
//Set proxy to null. Under current configuration if this option is not set then the proxy that is used will get an html response from the web content gateway (firewall monitoring system)
request.Proxy = null;
request.UsePassive = true;
request.UseBinary = true;
request.KeepAlive = keepAlive;
request.Credentials = new NetworkCredential(userName, password);
return request;
}
private void button1_Click(object sender, EventArgs e)
{
DownloadFile("Username1", "Password1", "ftp://172.32.1.252:5010/Test/CBRE/building.csv", "C://Workspace/ex.csv");
}

I dont understand exactly what you are trying to do, but you can try this wat too:
WebClient Client = new WebClient ();
Client.DownloadFile(http://www.domain.com/files/yourfile.ext, " yourfile.ext");
WebClientClass

Download and open picture from url/http [Android Xamarin App]

Hello, would any of you send a working code to download a photo from a given http address on android Xamarin c #?
First, I need to create a new folder for my application files.
My goal is to download the file from the internet to my Android folder (saving this file with its original name is best).
The next step is to display the image from that folder in "ImageView". It is also important that there are permissions in android and I do not fully understand it.
Could any of you send it to me or help me understand it and explain the topic?
*Actually i have this code:
string address = "https://i.stack.imgur.com/X3V3w.png";
using (WebClient webClient = new WebClient())
{
webClient.DownloadFileCompleted += WebClient_DownloadFileCompleted;
webClient.DownloadFile(address, Path.Combine(pathDire, "MyNewImage1.png"));
//System.Net.WebException: 'An exception occurred during a WebClient request.'
}
Loading image from url and display in imageview.
private void Btn1_Click(object sender, System.EventArgs e)
{
var imageBitmap = GetImageBitmapFromUrl("http://xamarin.com/resources/design/home/devices.png");
imagen.SetImageBitmap(imageBitmap);
}
private Bitmap GetImageBitmapFromUrl(string url)
{
Bitmap imageBitmap = null;
using (var webClient = new WebClient())
{
var imageBytes = webClient.DownloadData(url);
if (imageBytes != null && imageBytes.Length > 0)
{
SavePicture("ImageName.jpg", imageBytes, "imagesFolder");
imageBitmap = BitmapFactory.DecodeByteArray(imageBytes, 0, imageBytes.Length);
}
}
return imageBitmap;
}
download image and save it in local storage.
private void SavePicture(string name, byte[] data, string location = "temp")
{
var documentsPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal);
documentsPath = System.IO.Path.Combine(documentsPath, "Orders", location);
Directory.CreateDirectory(documentsPath);
string filePath = System.IO.Path.Combine(documentsPath, name);
using (FileStream fs = new FileStream(filePath, FileMode.OpenOrCreate))
{
int length = data.Length;
fs.Write(data, 0, length);
}
}
you need to add permission WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE in AndroidMainfeast.xml, then you also need to Runtime Permission Checks in Android 6.0.
private void checkpermission()
{
if (ContextCompat.CheckSelfPermission(this, Manifest.Permission.WriteExternalStorage) == (int)Permission.Granted)
{
// We have permission, go ahead and use the writeexternalstorage.
}
else
{
// writeexternalstorage permission is not granted. If necessary display rationale & request.
}
if (ContextCompat.CheckSelfPermission(this, Manifest.Permission.ReadExternalStorage) == (int)Permission.Granted)
{
// We have permission, go ahead and use the ReadExternalStorage.
}
else
{
// ReadExternalStorage permission is not granted. If necessary display rationale & request.
}
}

Why am I getting a "NotSupportedException" with this code?

I am trying to call a Web API method from a handheld device (Compact Framework) with this code:
// "fullFilePath" is a value such as "\Program Files\Bla\abc.xml"
// "uri" is something like "http://localhost:28642/api/ControllerName/PostArgsAndXMLFile?serialNum=8675309&siteNum=42"
SendXMLFile(fullFilePath, uri, 500);
. . .
public static string SendXMLFile(string xmlFilepath, string uri, int timeout)
{
uri = uri.Replace('\\', '/');
if (!uri.StartsWith("/"))
{
uri = "/" + uri;
}
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.KeepAlive = false;
request.ProtocolVersion = HttpVersion.Version10;
request.Method = "POST";
StringBuilder sb = new StringBuilder();
using (StreamReader sr = new StreamReader(xmlFilepath))
{
String line;
while ((line = sr.ReadLine()) != null)
{
sb.AppendLine(line);
}
byte[] postBytes = Encoding.UTF8.GetBytes(sb.ToString());
if (timeout < 0)
{
request.ReadWriteTimeout = timeout;
request.Timeout = timeout;
}
request.ContentLength = postBytes.Length;
request.KeepAlive = false;
request.ContentType = "application/x-www-form-urlencoded"; // not "text/xml" correct?
try
{
Stream requestStream = request.GetRequestStream();
requestStream.Write(postBytes, 0, postBytes.Length);
requestStream.Close();
using (var response = (HttpWebResponse)request.GetResponse())
{
return response.ToString();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
request.Abort();
return string.Empty;
}
}
}
Somewhere in SendXMLFile(), it is failing with "NotSupportedException" though... As it's running on a handheld device, I can't put a breakpoint in it and step through it; I could sprinkle a bunch of debug statements throughout (MessageBox.Show()), but I'd rather not do that.
The server code never even reaches the breakpoint I put on the "XDocument doc =" line below:
[Route("api/ControllerName/PostArgsAndXMLFile")]
public void PostArgsAndFile([FromBody] string stringifiedXML, string serialNum, string siteNum)
{
XDocument doc = XDocument.Parse(stringifiedXML);
Is it that the Compact framework can't call a (RESTful) Web API method for some reason? Obviously, the client (handheld/Compact Framework) compiles and runs, it just refuses to actually follow through with the runtime realities of it all.
Does my code require a small alteration for it to fit, or do I need to take a completely different tack?
Web API is not going to be able to handle your body content. You declared it as application/x-form-urlencoded, but it is actually XML formatted and your method signature is expecting it to be a XMLDataContract serialized string.
Instead of using the parameter stringifiedXML, instead, just read the body inside your method..
[Route("api/ControllerName/PostArgsAndXMLFile")]
public async void PostArgsAndFile(string serialNum, string siteNum)
{
XDocument doc = XDocument.Parse(await Request.Content.ReadAsStringAsync());
}
Or event better, use a stream directly.
[Route("api/ControllerName/PostArgsAndXMLFile")]
public async void PostArgsAndFile(string serialNum, string siteNum)
{
XDocument doc = XDocument.Load(await Request.Content.ReadAsStreamAsync());
}
This way, you can put the ContentType on the client back to application/xml as it should be.
Using Darrel's code on the server side (I'm using the second one, the Stream), this works on the Client side:
public static string SendXMLFile(string xmlFilepath, string uri, int timeout)
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
request.KeepAlive = false;
request.ProtocolVersion = HttpVersion.Version10;
request.ContentType = "application/xml";
request.Method = "POST";
StringBuilder sb = new StringBuilder();
using (StreamReader sr = new StreamReader(xmlFilepath))
{
String line;
while ((line = sr.ReadLine()) != null)
{
sb.AppendLine(line);
}
byte[] postBytes = Encoding.UTF8.GetBytes(sb.ToString());
if (timeout < 0)
{
request.ReadWriteTimeout = timeout;
request.Timeout = timeout;
}
request.ContentLength = postBytes.Length;
request.KeepAlive = false;
request.ContentType = "application/x-www-form-urlencoded";
try
{
Stream requestStream = request.GetRequestStream();
requestStream.Write(postBytes, 0, postBytes.Length);
requestStream.Close();
using (var response = (HttpWebResponse)request.GetResponse())
{
return response.ToString();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
request.Abort();
return string.Empty;
}
}
}
Which can be called like so:
private void buttonNose_Click(object sender, EventArgs e)
{
String fullFilePath = #"C:\McMurtry\LonesomeDove.XML";
String uri = #"http://localhost:21608/api/inventory/sendxml/ff/gg/42";
SendXMLFile(fullFilePath, uri, 500);
}

How to upload images to facebook which is selected by using photoChooserTask in windows phone 8?

I am developing a Windows Phone app in which I have to post a photo to facebook. And that particular photo is choosen by using PhotoChooserTask or CameraChooserTask.
Normally, I can post a particular photo successfully, but I am facing problem to post the selected photo. I saw some link like
link
So please if anyone know about the issue please help me out.
Thanx in advance.
EDIT

{
//Client Parameters
var parameters = new Dictionary<string, object>();
//var parameters1 = new Dictionary<>();
parameters["client_id"] = FBApi;
parameters["redirect_uri"] = "https://www.facebook.com/connect/login_success.html";
parameters["response_type"] = "token";
parameters["display"] = "touch";
parameters["ContentType"] = "image/png";
//The scope is what give us the access to the users data, in this case
//we just want to publish on his wall

}
else
{

MessageBox.Show(oauthResult.ErrorDescription);
Browser.Visibility = System.Windows.Visibility.Collapsed;
}
}
private void PostToWall()
{
string imageName = "ic_launcher.png";
StreamResourceInfo sri = null;
Uri jpegUri = new Uri(imageName, UriKind.Relative);
sri = Application.GetResourceStream(jpegUri);
try
{
byte[] imageData = new byte[sri.Stream.Length];
sri.Stream.Read(imageData, 0, System.Convert.ToInt32(sri.Stream.Length));
FacebookMediaObject fbUpload = new FacebookMediaObject
{
FileName = imageName,
ContentType = "image/jpg"
};
fbUpload.SetValue(imageData);
string name1 = eventname.Text;
string format = "yyyy-MM-dd";
string message1 = eventmessage.Text;
string date1 = datepicker.ValueString;
DateTime datevalue = DateTime.Parse(date1);
string d = datevalue.ToString(format);
string memoType = "Tribute";
var parameters = new Dictionary<string, object>();
var parameters1 = new Dictionary<string, object>();
parameters["message"] = name1 + "\n" + d + "\n" + memoType + "\n" + message1;
parameters["source"] = fbUpload;
webservice();
client.PostTaskAsync("me/photos", parameters);
}
catch (Exception error)
{
MessageBox.Show(error.ToString());
}
//client.PostTaskAsync("me/photos", parameters1);
}
On clicking on a button I am calling PostClicked class and it will directly go to facebook mainpage and it will ask for login information. Like this I am doing.
Please check it out
Now I can share a photo to facebook successfully by using photochoosertask or cameratask.
I am sharing my experience so that if anyone face the same issue can use it.
private void photoChooserTask_Completed(object sender, PhotoResult e)
{
BitmapImage image = new BitmapImage();
image.SetSource(e.ChosenPhoto);
SaveImageToIsolatedStorage(image, tempJPEG);
this.image.Source = image;
}
public void SaveImageToIsolatedStorage(BitmapImage image, string fileName)
{
using (var isolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
if (isolatedStorage.FileExists(fileName))
isolatedStorage.DeleteFile(fileName);
var fileStream = isolatedStorage.CreateFile(fileName);
if (image != null)
{
var wb = new WriteableBitmap(image);
wb.SaveJpeg(fileStream, wb.PixelWidth, wb.PixelHeight, 0, 100);
}
fileStream.Close();
}
}
With this you can able to save the selected image to IsolatedStorage.
And then at the time of posting the photo to facebook you have to select the image from IsolatedStorage.

Thanx to all....
you can do that by two methods :
1) by using mediasharetask in which it will show u all sharing account to which your phone is synced like facebook,gmail,linkdin,twitter,etc : it can be used like like this.
ShareMediaTask shareMediaTask = new ShareMediaTask();
shareMediaTask.FilePath = path;
shareMediaTask.Show();
2) by using facebook sdk. you can get the package from nuget manager and then u can use it to share on facebook.
I hope this might help u.

FTP file (.csv) download gets truncated

This downloads a .csv file using FTP. The file is 46k on the server. When I download, it gets truncated to 44k. I have no idea why ... when I view the data in Excel, it is cut short. I increased the buffer to 4096 but no dice (this probably isn't the problem).
I originally grabbed the following code and tweaked it from: Downloading Files Using FTPWebRequest
Any thoughts appreciated ! Thanks.
private void DownloadFile(string userName, string password, string ftpSourceFilePath, string localDestinationFilePath)
{
int bytesRead = 0;
byte[] buffer = new byte[2048];
FtpWebRequest request = CreateFtpWebRequest(ftpSourceFilePath, userName, password, false);
request.Method = WebRequestMethods.Ftp.DownloadFile;
Stream reader = request.GetResponse().GetResponseStream();
FileStream fileStream = new FileStream(localDestinationFilePath, FileMode.Create);
while (true)
{
bytesRead = reader.Read(buffer, 0, buffer.Length);
if (bytesRead == 0)
break;
fileStream.Write(buffer, 0, bytesRead);
}
}
private FtpWebRequest CreateFtpWebRequest(string ftpDirectoryPath, string userName, string password, bool keepAlive)
{
FtpWebRequest request = (FtpWebRequest)WebRequest.Create(new Uri(ftpDirectoryPath));
//Set proxy to null. Under current configuration if this option is not set then the proxy that is used will get an html response from the web content gateway (firewall monitoring system)
request.Proxy = null;
request.UsePassive = true;
request.UseBinary = true;
request.KeepAlive = keepAlive;
request.Credentials = new NetworkCredential(userName, password);
return request;
}
Try this approach:
private void DownloadFile(string userName, string password, string ftpSourceFilePath, string localDestinationFilePath)
{
int Length = 2048;
Byte[] buffer = new Byte[Length];
int bytesRead = responseStream.Read(buffer, 0, Length);
FtpWebRequest request = CreateFtpWebRequest(ftpSourceFilePath, userName, password, false);
request.Method = WebRequestMethods.Ftp.DownloadFile;
Stream reader = request.GetResponse().GetResponseStream();
FileStream fileStream = new FileStream(localDestinationFilePath, FileMode.Create);
while (bytesRead > 0)
{
//if (bytesRead == 0)
// break;
bytesRead = responseStream.Read(buffer, 0, Length);
fileStream.Write(buffer, 0, bytesRead);
}
fileStream.Close();
}

Please try to change
request.Method = "Post"
to
request.Method = "Get"
If you are running into this problem on the emulator, have you tried running Fiddler? It will intercept the HTTP requests and you can see if the call being made to the server is the one you expect.
Remember to close/reopen the emulator after you start Fiddler so that it will pick up the proxy.
The NotFound response can also occur with bad SSL certificates. That doesn't appear to be related to your problem, but something to keep in mind.
