新邮件，嘿，有点简单，容易

很多人都有过使用网络蚂蚁或网络快车软件下载互联网文件的经历，这些软件的使用可以大大加速互联网上文件的传输速度，减少文件传输的时间。这些软件为什么有如此大的魔力呢？其主要原因是这些软件都采用了多线程下载和断点续传技术。如果我们自己来编写一个类似这样的程序，也能够快速的在互联网上下载文件，那一定是非常愉快的事情。下面我就讲一讲如何利用C#语言编写一个支持多线程下载文件的程序，你会看到利用C#语言编写网络应程序是多么的容易，从中也能体会到C#语言中强大的网络功能。 -many people use the Internet, they had ants Network Express software or download files over the Internet experience, the use of such software can greatly speed up the documents on the Internet speeds, reduce file transfer time. These software Why is there so much magic? Its main reason is the software used to download and multithreading technology HTTP. If we prepare ourselves to a similar case in the process and to quickly download on the Internet, it must be a very pleasant thing. Now, I would talk about how to use C# language support for a multi-threaded download procedures, you will see the use of C# language network should procedure is how easy from can understand C# Language powerful networking capabilities.

信使小精灵,是一个简易的聊天工具。主要是演示了网络编程的主要步骤。本程序使用封装好的函数库，使得应用层不需要考虑网络消息是如何被接受和发送的，也不需要考虑数据粘包和丢包的刺手问题，你只要调用相应的函数就可以了。函数库为你做好了这些工作。你只需要定义自己的协议头和消息结构体，定义好网络消息的回调函数就可以了。-Messenger elf is a simple chat tool. Mainly to demonstrate the major steps in network programming. This procedure using the package a good library, making the application layer does not need to consider how the network news is accepted and sent, nor need to consider the data packet and packet loss sticky hands of the Spurs, you simply call the corresponding function can be a . Function library for you to do a good job in those efforts. You only need to define your own protocol header and message structure, the definition of good network news can be a callback function.

Client程序同样分别创建一个TCP socket 和一个UDP socket，首先client使用TCP socket连接TCP Server。 连接成功后显示提示信息； 然后client端向TCP Server发送“GET UDP PORT”字符串，Server收到后向client回送自己的UDP Server 端口号（即Client端仅知道TCP Server的端口号而不知道UDP Server的端口号）； client在收到UDP Server的端口号后, 为用户显示3个选项： 1．“Get current time（TCP）”服务器时间 2．“Echo Mode（UDP）”回显6 3．“Exit the program”. -Client program also creates a TCP socket, respectively, and a UDP socket, the first client to use TCP socket connection TCP Server. After a successful connection displays a prompt message and then client-side to the TCP Server sends " GET UDP PORT" string, Server receipt back to the client to send their UDP Server port number (ie, Client-side only to know the TCP Server" s UDP port number do not know Server" s port number) client received UDP Server port number, in order to the user three options: 1. " Get current time (TCP)" server time 2. " Echo Mode (UDP)" echo 63. " Exit the program" .
