WinRAR(WinZip)压缩与解压实现（C#版Window平台）

傷城~ 2023-10-17 20:23 122阅读 0赞

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

<table style="float: left;"> 
 <tbody> 
 <tr> 
 <td style="text-align: center;"> 参数 </td> 
 <td style="text-align: center;"> 含义 </td> 
 </tr> 
 <tr> 
 <td> a </td> 
 <td> 添加文件到压缩包 </td> 
 </tr> 
 <tr> 
 <td> x </td> 
 <td> 以完整路径从压缩包解开压缩 </td> 
 </tr> 
 </tbody> 
</table>
