WinRAR(WinZip)壓縮與解壓實現（C#版Window平台）

本文的原理是借助Windows平台安裝的WinRAR(WinZip)實現C#程序的調用（注：WinRAR壓縮解壓WinZip同樣適用）。

 

先來看WinRAR（WinZip）自身的支持調用命令：

壓縮命令：a {0} {1} -r 【{0}：壓縮后文件名|{1}：待壓縮的文件物理路徑】

ex:"a 你妹.rar f:\\MM -r" （含義為將f盤下MM的文件夾壓縮為"你妹.rar"文件）

解壓命令：x {0} {1} -y 【{0}：待解壓文件名稱|{1}：待解壓文件物理路徑】

ex:"x 幺妹.rar f:\\幺妹 -y"（待壓縮文件物理路徑："f:\\幺妹\\幺妹.rar"）

 

參數說明

參數	含義
a	添加文件到壓縮包
x	以完整路徑從壓縮包解開壓縮

調用方法

WinRARCSharp win = new WinRARCSharp();

win.RAR("F:\\aaa\\", "f:\\", "a.rar")； // 壓縮（將“f:\\aaa\\”目錄文件壓縮到“f:\\a.rar”）

win.UnRAR("f:\\呦M.zip", "f:\\MM", "GG"); // 解壓（將“f:\\呦M.zip”解壓到“f：\\MM\\GG”目錄下）
