WP7: Sending "POST" data and receive response

Let's send "POST" data from our Windows Phone and get response.

1. Create Windows Phone Application named "SendPOSTdata".
2. In MainPage.xaml.cs include some "using":
   

   using System;
   using System.IO;
   using System.Text;
   using System.Diagnostics;
   using System.Net;
   using System.Windows;
   using Microsoft.Phone.Controls;
   

3. Create loaded event handler:
   

   using System;
   public MainPage()
   {
       InitializeComponent();
   
       Loaded += new RoutedEventHandler(MainPage_Loaded);
   }
   
   void MainPage_Loaded(object sender, RoutedEventArgs e)
   {
       System.Uri myUri = new System.Uri("http://myPageUrlAddress.com/");
       HttpWebRequest myRequest = (HttpWebRequest)HttpWebRequest.Create(myUri);
       myRequest.Method = "POST";
       myRequest.ContentType = "application/x-www-form-urlencoded";
       myRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback),myRequest);
   }
   

4. Now we need create our "POST" data stream:
   

   void GetRequestStreamCallback(IAsyncResult callbackResult)
   {
       HttpWebRequest myRequest = (HttpWebRequest)callbackResult.AsyncState;
       // End the stream request operation
       Stream postStream = myRequest.EndGetRequestStream(callbackResult);
   
       // Create the post data
       string postData = "param1=value1&param2=value2";
       byte[] byteArray = Encoding.UTF8.GetBytes(postData);
   
       // Add the post data to the web request
       postStream.Write(byteArray, 0, byteArray.Length);
       postStream.Close();
   
       // Start the web request
       myRequest.BeginGetResponse(new AsyncCallback(GetResponsetStreamCallback), myRequest);
   }
   

5. And at the end receive response:
   

   void GetResponsetStreamCallback(IAsyncResult callbackResult)
   {
       HttpWebRequest request = (HttpWebRequest)callbackResult.AsyncState;
       HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(callbackResult);
       using (StreamReader httpWebStreamReader = new StreamReader(response.GetResponseStream()))
       {
           string result = httpWebStreamReader.ReadToEnd();
           //For debug: show results
           Debug.WriteLine(result);
       }
   }
   

6. Run.
