执行这个函数后程序变得没有响应.关于TcpListener

Question

public void StartListen()//侦听特定端口的用户请求 
        {
            try
            {                Int32 port = 13000;
                IPAddress localAddr = IPAddress.Parse("127.0.0.1");
                TcpListener server = new TcpListener(localAddr, port);
                server.Start();
                Byte[] bytes = new Byte[256];
                String data = null;
                while (true)
                {
                    ListActive.Text = "Waiting for a connection...";
                    TcpClient client = server.AcceptTcpClient();
                    ListActive.Text = "Connected!";
                    data = null;
                    NetworkStream stream = client.GetStream();
                    int i;
                    while ((i = stream.Read(bytes, 0, bytes.Length)) != 0)
                    {
                        data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
                        data = data.ToUpper();
                        byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);
                        stream.Write(msg, 0, msg.Length);           
                    }
                    client.Close();
                }
            }
            catch (SocketException e)
            {
                Console.WriteLine("SocketException: {0}", e);
            }
            Console.WriteLine("\nHit enter to continue...");
            Console.Read();
        }

程序死掉了，可能是多方面的原因，你自己用Debug来输出一下，看看是到了哪一步出错了。
