Windows Phone套接字编程

Question

我想使用windows phone 7.5（MANGO）上的套接字连接到http服务器。代码如下所示：

public class sockets 
    { 
     // Buffer for incoming data 
     private byte[] _receiveBuffer; 

     public void Demo() 
     { 
      String host = "209.85.148.106"; 
      int port = 80; 
     String Message = "GET/HTTP/1.1 Host: google.pl User-Agent: Mozilla/5.0 (X11; U; Linux i686; pl; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7 Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8 Accept-Language: pl,en-us;q=0.7,en;q=0.3 Accept-Charset: ISO-8859-2,utf-8;q=0.7,*;q=0.7\r\n"; 

     // create endpoint 
     var ipAddress = IPAddress.Parse(host); 
     var endpoint = new IPEndPoint(ipAddress, port); 

     // convert text to send (prefix with length) 
     //var message = string.Format("{0};{1}", Message.Length, Message); 
     var buffer = Encoding.UTF8.GetBytes(Message); 

     // create event args 
     var args = new SocketAsyncEventArgs(); 
     args.RemoteEndPoint = endpoint; 
     args.Completed += SocketAsyncEventArgs_Completed; 
     args.SetBuffer(buffer, 0, buffer.Length); 

     // create a new socket 
     var socket = new Socket(AddressFamily.InterNetwork, 
      SocketType.Stream, 
      ProtocolType.Tcp); 

     // connect socket 
     bool completesAsynchronously = socket.ConnectAsync(args); 

     // check if the completed event will be raised. 
     // if not, invoke the handler manually. 
     if (!completesAsynchronously) 
     { 
      SocketAsyncEventArgs_Completed(args.ConnectSocket, args); 
     } 
    } 

    private void SocketAsyncEventArgs_Completed(object sender, SocketAsyncEventArgs e) 
    { 
     // check for errors 
     if (e.SocketError != SocketError.Success) 
     { 
      System.Diagnostics.Debug.WriteLine(e.ToString()); 
      return; 
     } 

     // check what has been executed 
     switch (e.LastOperation) 
     { 
      case SocketAsyncOperation.Connect: 
       HandleConnect(e); 
       break; 
      case SocketAsyncOperation.Send: 
       HandleSend(e); 
       break; 
      case SocketAsyncOperation.Receive: 
       HandleReceive(e); 
       break; 
      case SocketAsyncOperation.ReceiveFrom: 
       HandleReceive(e); 
       break; 
     } 
    } 

    private void HandleConnect(SocketAsyncEventArgs e) 
    { 
     if (e.ConnectSocket != null) 
     { 
      // simply start sending 
      bool completesAsynchronously = e.ConnectSocket.SendAsync(e); 

      // check if the completed event will be raised. 
      // if not, invoke the handler manually. 
      if (!completesAsynchronously) 
      { 
       SocketAsyncEventArgs_Completed(e.ConnectSocket, e); 
      } 
     } 
    } 

    private void HandleSend(SocketAsyncEventArgs e) 
    { 
     System.Diagnostics.Debug.WriteLine("WYSLANO"); 

     // simply start sending 
     bool completesAsynchronously = e.ConnectSocket.ReceiveAsync(e); 

     // check if the completed event will be raised. 
     // if not, invoke the handler manually. 
     if (!completesAsynchronously) 
     { 
      SocketAsyncEventArgs_Completed(e.ConnectSocket, e); 
     } 
    } 

    private void HandleReceive(SocketAsyncEventArgs e) 
    { 
     System.Diagnostics.Debug.WriteLine("ODEBRANO"); 


    } 
} 

一些代码都是由手工等，其试图连接到http://google.pl是发送数据，但没有收到任何东西。

我看到您在邮件末尾发送一个回车/换行符。您需要发送两个信号表明您已完成您的请求。

虽然更好的选择可能是使用HttpWebRequest类的WebClient类，因为它们都会为您发送正确构建的HTTP请求。
