silverlighthttppost几个变量,最简单的例子(最少的代码)

你好,我想发布一些数据从silverlight到一个网站。
我发现如下 link 而且很有效。。。
这个例子太复杂了,我的眼睛都痛了。
也。。flex示例更简洁/代码更少。。

供参考。。我们发布2个变量(字符串)并读取结果(字符串)。

   1. // C#  
   2. // Create a request object  
   3. HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(POST_ADDRESS, UriKind.Absolute));  
   4. request.Method = "POST";  
   5. // don't miss out this  
   6. request.ContentType = "application/x-www-form-urlencoded";  
   7. request.BeginGetRequestStream(new AsyncCallback(RequestReady), request);  
   8.   
   9. // Sumbit the Post Data  
  10. void RequestReady(IAsyncResult asyncResult)  
  11. {  
  12.     HttpWebRequest request = asyncResult.AsyncState as HttpWebRequest;  
  13.     Stream stream = request.EndGetRequestStream(asyncResult);  
  14.   
  15.     // Hack for solving multi-threading problem  
  16.     // I think this is a bug  
  17.     this.Dispatcher.BeginInvoke(delegate()  
  18.     {  
  19.         // Send the post variables  
  20.         StreamWriter writer = new StreamWriter(stream);  
  21.         writer.WriteLine("key1=value1");  
  22.         writer.WriteLine("key2=value2");  
  23.         writer.Flush();  
  24.         writer.Close();  
  25.   
  26.         request.BeginGetResponse(new AsyncCallback(ResponseReady), request);  
  27.     });  
  28. }  
  29.   
  30. // Get the Result  
  31. void ResponseReady(IAsyncResult asyncResult)  
  32. {  
  33.     HttpWebRequest request = asyncResult.AsyncState as HttpWebRequest;  
  34.     HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asyncResult);  
  35.   
  36.     this.Dispatcher.BeginInvoke(delegate()  
  37.     {  
  38.         Stream responseStream = response.GetResponseStream();  
  39.         StreamReader reader = new StreamReader(responseStream);  
  40.     // get the result text  
  41.         string result = reader.ReadToEnd();  
  42.     });  
  43. }
