Socket的问题

Question

全部代码如下,运行
void button1_Click_1(object sender, EventArgs e)
后,程序会死掉.
请问是什么原因?

Answer 1

acceptedSocket = socket.Accept();        一直等到有连接近来以后程序才会有反映,否则一直阻塞到超时.
改用异步或者后台线程吧.参考这个贴中,最后三贴我的回复

Answer 2

acceptedSocket = socket.Accept();
if(acceptSocket == Null)
{
  return;
}

Answer 3

用异步调用啊！
非异步调用的线程会一直等待cli_sSocket.BeginAccept(new AsyncCallback(AcceptConnection), cli_sSocket);然后自写AcceptConnection事件
