use Helper Classes to simplify you network programming

C# Sockets Helper Classes是用来简化.net Socket网络编程的一组辅助类,主要有:(1)TcpListener (2)TcpClient (3)UdpClient。(1)(2)用来简化tcp编程。(3)用来简化Udp编程。采用这些Helper Classes能够带来很多便利。

1)省去了tcp,udp编程的一些步骤,缩减编写代码的长度。比如以前建立一个Tcp Server需要如下步骤:
IPAddreess addr=IPAddreess.Parse("127.0.0.1");
IPEndPoint ipep=new IPEndPoint (addr,8004);
Socket serverSocket=new Socket("略");
serverSocket.bind(ipep);
serverSocket.listen(10);
现在只需要如下几步:
TcpListener listener=new TcpListener(8004);
listener.Start();

2)把Socket编程封装,暴露高级接口,使利于交互。比如Tcp编程可以通过流的形式在一个连接上交互,容易读写和确定消息的边界。比如Udp编程,以前如果提供的接收消息的buffer小于消息的长度的话,会抛出异常,此条消息就丢失了,现在通过UdpClient就不会有这种现象发生,UdpClient的Receive函数会自动返回更大的buffer的数据。
