客户：

Client:

    {
        System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();

        public Form1()

MSDN上有一些很好的入门示例。

套接字代码示例 [ ^ ]



你***先看看那里，忘记你到目前为止所编写的代码。

特别是在异步服务器套接字示例中查看>。

（这就是谢尔盖所说的）

客户可以是或者，根据您的需要。

There are some good "getting-started" examples on MSDN.
Socket Code Examples[^]

It is better that you start looking there and kind of forget about the code you have written so far.
Especially look in the the Asynchronous Server Socket Example.
(This is what Sergey is talking about)
The client can be either or, depending on your needs.
