写一个聊天的程序可是有点问题,帮忙看看
public void Listen()
{
try
{
TcpListener tcpl = new TcpListener(8080);
tcpl.Start();
toolStripStatusLabel1.Text = "正在监听。。。";
while (true)
{
Socket s = tcpl.AcceptSocket();//运行到这里就不动了

byte[] stream = new byte[80];
int i = s.Receive(stream);
string message = System.Text.Encoding.UTF8.GetString(stream);
richTextBox1.AppendText(message);

}
}
catch (System.Security.SecurityException)
{
MessageBox.Show("防火墙错误", "错误", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
catch(Exception)
{
toolStripStatusLabel1.Text = "停止监听";
}
}

谢谢拉!!!

thread thread=new thread(new threadstart(Listen));
thread.start();


void Listen()
{
using(Socket listener=new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp))
{
listener.Bind(new IPEndPoint(IPAddress.Any,8080));
listener.Listen(backlog);

using(Socket socket=listener.Accept())
{
Stream netStream=new NetworkStream(socket);
StreamReader reader=new StreamReader(netStream);
string result=reader.ReadToEnd();

Invoke(new displayinfodelegate(displayinfo),new object[]{result});
}
}

}

void displayinfo(string str)
{
richTextBox1.AppendText(str);
}
delegate void displayinfodelegate(string str);

一看楼上的手笔就自叹不如啊.小声地问using(Socket socket=listener.Accept())的这种用法跟try有什么区别?

楼主的问题是因为listener没有监听到连接吧.可以用try试试看.

上面用try catch finall更好阿 在finally裡面寫dispose

我懶得多寫些代碼才寫using()
它也會在屁股後面dispose
不過這個類好像必須繼承idisposble接口才能用using

写的真不错
