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 |
