WinRAR(WinZip)压缩与解压实现（C#版Window平台）
本文的原理是借助Windows平台安装的WinRAR(WinZip)实现C#程序的调用（注：WinRAR压缩解压WinZip同样适用）。
先来看WinRAR（WinZip）自身的支持调用命令：
压缩命令：a {0} {1} -r 【{0}：压缩后文件名|{1}：待压缩的文件物理路径】
ex:"a 你妹.rar f:\\MM -r" （含义为将f盘下MM的文件夹压缩为"你妹.rar"文件）
解压命令：x {0} {1} -y 【{0}：待解压文件名称|{1}：待解压文件物理路径】
ex:"x 幺妹.rar f:\\幺妹 -y"（待压缩文件物理路径："f:\\幺妹\\幺妹.rar"）
参数说明
| 参数 |
含义 |
| a |
添加文件到压缩包 |
| x |
以完整路径从压缩包解开压缩 |
