1. 首先下载Raknet的源代码，我用的是4.0的，不是最新的，解压后编译DLL工程，编译完成后进入解压的根目录下，进入Lib文件夹下找到RakNet_DLL_Debug_Win32.dll， RakNet_DLL_Debug_Win32.lib这两个库文件，并将其关联到工程中。
2. 将解压目录下Source文件夹下的资源也管理到你的工程中
进行完上面两步就将网络库配置完成，下面便开始服务器端与客户端的程序编写
// 服务器端程序

ps: 下面是将网络库关联到你的工程中
1.右键工程--》属性--》c/c++ --》常规--》"附加包含目录"，将源文件和上面的两个文件包含进去
2.右键工程--》属性--》链接器 --》常规--》"附加包含目录"，将源文件和上面的两个文件包含进去
3.右键工程--》属性--》链接器 --》输入--》"附加依赖项"，添加 RakNet_DLL_Debug_Win32.lib 库
