About C # socket communication, is divided into synchronous and asynchronous communication, this brief synchronous communication.
Ends of the communication are client (Client) and a server (Server):
(1)Cient:
1: Create a Socket on the image;
2: () method of the above image EndPoint established as a parameter, a connection request to the server socket with the image of Connect;
3: If the connection is successful, a socket () method sends the information to the server on the Send image;
4: receive information sent from the server with the image of the Receive socket () method;
5: After the communication must remember to close Socket;

The client returns the result:
(2)Server:
1: Create a Socket on the image;
2: the image of the socket with the Bind () method of binding the EndPoint;
3: The socket on the image Listen () method starts listening;
4: received client connections, create a new socket with the socket of the image the Accept () method is used as the client and the requested communication;
5: receiving new socket object (the Receive) and a transmission (the Send) message.

关于C#socket通信，分为同步和异步通信，本文简单介绍一下同步通信。
通信两端分别为客户端（Client）和服务器(Server):
(1)Cient:
1：建立一个Socket对像；
2：用socket对像的Connect()方法以上面建立的EndPoint对像做为参数，向服务器发出连接请求；
3：如果连接成功，就用socket对像的Send()方法向服务器发送信息；
4：用socket对像的Receive()方法接受服务器发来的信息 ;
5：通信结束后一定记得关闭socket；

客户端返回结果:
(2)Server:
1：建立一个Socket对像；
2：用socket对像的Bind()方法绑定EndPoint；
3：用socket对像的Listen()方法开始监听；
4：接受到客户端的连接，用socket对像的Accept()方法创建新的socket对像用于和请求的客户端进行通信;
5：用新的socket对象接收（Receive）和发送（Send）消息。
