[转载]WinRAR(WinZip)压缩与解压实现(C#版Window平台) – Stone_W – 博客园.

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

win.RAR("F:\\aaa\\", "f:\\", "a.rar"); // 压缩(将“f:\\aaa\\”目录文件压缩到“f:\\a.rar”)

win.UnRAR("f:\\呦M.zip", "f:\\MM", "GG"); // 解压(将“f:\\呦M.zip”解压到“f:\\MM\\GG”目录下)
