超级终端断开连接，第一次发送数据可以收到，再发送就不行了，    再断开连接，重新连接第一次也可以收到，第二次就收不到了

那我该怎么写呢，求指教

你写出来我试试呗

你写一个程序能接收  XP超级终端发送信息   能连续接收就行

private void doReceive()
{
    while(true)
    {
        byte[] buff = new byte[1024];
        int receiveLength = tempSocket.Receive(buff);
        string msgStr = Encoding.Default.GetString(buff, 0, receiveLength);

        this.txt_sendInfo.Text += msgStr;
        
        判断终端是否断开连接,如果断开,就退出while循环
    }
}


没有 Socket tempSocket = socket_listen_request.Accept();  这一句      
int receiveLength = tempSocket.Receive(buff);能用?

好吧。
