TCPClient似乎不维持保持连接状态，为什么？

Question

我使用的TcpClient下面的代码

byte[] encbuff = System.Text.Encoding.UTF8.GetBytes("username" + ":" + "password"); 
     string follow = "track=soccer,twitter"; 
     byte[] encode_follow = System.Text.Encoding.UTF8.GetBytes(follow); 

     using (TcpClient client = new TcpClient()) 
     { 
      string requestString = "POST /1/statuses/filter.json HTTP/1.1\r\n"; 
      requestString += "Host: stream.twitter.com\r\n"; 
      requestString += "User-Agent: www.site.com\r\n"; 
      requestString += "Referer: http://www.site.com\r\n"; 
      requestString += "Content-Type: application/x-www-form-urlencoded\r\n"; 
      requestString += "Authorization: " + "Basic " + Convert.ToBase64String(encbuff) + "\r\n"; 
      requestString += "Content-length: " + follow.Length + "\r\n"; 
      requestString += "Connection: keep-alive\r\n"; 
      requestString += "\r\n"; 
      requestString += follow; 
      requestString += "\r\n\r\n"; 

      client.Connect("stream.twitter.com", 80); 
      //client.ReceiveTimeout = 100; 
      using (NetworkStream stream = client.GetStream()) 
      { 
       // Send the request. 
       StreamWriter writer = new StreamWriter(stream); 
       writer.Write(requestString); 
       writer.Flush(); 

       // Process the response. 

        StreamReader rdr = new StreamReader(stream); 

        while (!rdr.EndOfStream) 
        { 
         Console.WriteLine(rdr.ReadLine()); 
         Console.WriteLine("IS end: " + rdr.EndOfStream.ToString()); 
        } 
       } 

     } 

会发生什么事是，虽然Console.WriteLine命令（rdr.ReadLine（））;行会打印出几秒钟的状态，而不是停止+不再触及断点，即使它仍然连接。

什么应该做的是继续写状态的控制台，因为它是一个保持活动连接和“推特”关键字获取每隔几秒钟不断提过几次。

任何想法可能会造成这个问题？

检查了这一点：

public class Program 
{ 
    public static void Main() 
    { 
     using (var client = new WebClient()) 
     { 
      client.Credentials = new NetworkCredential("username", "password"); 
      client.OpenReadCompleted += (sender, e) => 
      { 
       using (var reader = new StreamReader(e.Result)) 
       { 
        while (!reader.EndOfStream) 
        { 
         // TODO: feed this to your favorite JSON parser 
         Console.WriteLine(reader.ReadLine()); 
        } 
       } 
      }; 
      client.OpenReadAsync(new Uri("http://stream.twitter.com/1/statuses/filter.json?track=soccer,twitter")); 
     } 
     Console.ReadLine(); 
    } 
} 

应该让事情变得更容易。
