C#Socket处理多个连接 Socket监听多个连接并进行处理] 思路: 1.创建一个Socket对象用于服务器监听客户端的连接 2.当有客户端连接上之后,新开一个线程为不停的去接受该连接发送的消息并进行处理 3.服务端的Socket对象继续监听其他客户端的连接 4.服务器端每监听到一个连接,就创建一个线程为该连接进行处理实现Socket监听多个连接理解上面的思路如果你对一定基础,应该就能自己写出来了阅读详情

Thread.Sleep(1000);//10000单位是毫秒，系统在运行过程中，稍微有点停顿，个人感觉会更好一点。

那行代码出现了问题，提示由于套接字没有连接并且(当使用一个 sendto 调用发送数据报套接字时)没有提供地址，发送或接收数据的请求没有被接受。我很纳闷，查了半天网上，都没有解决，求各位大神帮忙看看
