tcp通讯，为什么执行AcceptTcpClient()的时候没有响应呢？

刚学习tcp通讯，但下面的代码老是没有响应，为什么？
TcpListener tcplistener = new TcpListener(IPAddress.Parse("127.0.0.1"),13);
tcplistener.Start();
byte[] btServerReceive = new byte[256];
string strServerReceive = string.Empty;

while (true)
{
    TcpClient tcp = tcplistener.AcceptTcpClient();
    NetworkStream ns = tcp.GetStream();
    int intReceiveLength = ns.Read(btServerReceive, 0, btServerReceive.Length);
    strServerReceive = UnicodeEncoding.Unicode.GetString(btServerReceive, 0, intReceiveLength);
    txtServerResult.AppendText("ServerReceive:" + strServerReceive + " ");
    ns.Write(btServerReceive, 0, btServerReceive.Length);
    txtServerResult.AppendText("ServerSend:" + strServerReceive + " ");
    tcp.Close();
}

建议先查查MSDN

AcceptTcpClient()是一直阻塞的 直到有客户端执行Connect 你单单执行这一块代码 到AcceptTcpClient()没有响应才是最正常的了

要等client发消息过来了才有响应，所以最好放在一个线程里

看看，觉得没看懂你那是啥代码
