C＃Socket连接错误

我在C＃插座工作，我得到了以下错误：C＃Socket连接错误

A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied

下面是我执行的代码：

private void HostSubscriberService() 
    { 
     IPAddress ipV4 = PublisherService.ReturnMachineIP(); 

     var localEP = new IPEndPoint(ipV4, _port); 
     var server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); 
     server.Bind(localEP); 

     StartListening(server); 
    } 

    private void StartListening(Socket server) 
    { 
     EndPoint remoteEP = new IPEndPoint(IPAddress.Any, 0); 
     while (true) 
     { 
      var data = new byte[1024]; 
      int recv = server.ReceiveFrom(data, ref remoteEP); 
      string messageSendFromClient = Encoding.ASCII.GetString(data, 0, recv); 

      MessageBox.Show(messageSendFromClient); 
     } 
    }

错误发生@int recv = server.ReceiveFrom(data, ref remoteEP);

我只需要侦听新的传入连接，然后打印从新客户端发送的消息。

我需要对TCP协议的工作，因为有些消息会> 1500个字节

谢谢！

哥们，ReceiveFrom（）是对UDP，使用接受（）和接收（）用于TCP – codymanix 2011-04-07 14:13:19

您需要.BeginAccept（）才能接收。

Here's a link with a sinple Asynchronous Socket Server example

注BeginAccept（）异步工作 – codymanix 2011-04-07 14:15:52

啊！好吧，'ReceiveFrom'是UDP。有没有办法从使用TCP的连接客户端获得'EndPoint'？ – 2011-04-07 14:25:13

@joe_coolish：[RemoteEndPoint]（http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.remoteendpoint.aspx）MSDN是你的朋友:) – NKCSS 2011-04-07 14:27:17
