How to send data to authenticate to the server? Using the current code:

WebClient MyWebClient = new WebClient();
        MyWebClient.OpenWriteCompleted += new OpenWriteCompletedEventHandler(MyWebClient_OpenWriteCompleted);
        MyWebClient.Headers["User-Agent"] = "Mozilla/4.0 (compatible; ICS)";
        MyWebClient.OpenWriteAsync(new Uri("http://myserver.com/login"), "POST", "email=[e-mail]&pass=mypassword");


    void MyWebClient_OpenWriteCompleted(object sender, OpenWriteCompletedEventArgs e)
    {

How to make a Post request?

Answer 1

//Making a POST request using WebClient.


Function()
{    
  WebClient wc = new WebClient();

  var URI = new Uri("http://your_uri_goes_here");

//If any encoding is needed.

  wc.Headers["Content-Type"] = "application/x-www-form-urlencoded";

//Or any other encoding type.

//If any key needed

  wc.Headers["KEY"] = "Your_Key_Goes_Here";

 wc.UploadStringCompleted += new UploadStringCompletedEventHandler(wc_UploadStringCompleted);

 wc.UploadStringAsync(URI,"POST","Data_To_Be_sent");    

}

void wc__UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)

{  

  try            
  {          
     MessageBox.Show(e.Result); 

//e.result fetches you the response against your POST request.

 }

  catch(Exception exc)         
  {             
     MessageBox.Show(exc.ToString());            
  }

}
