由于版本更新需要，研究了下调用WinRAR软件进行解压缩。

1. 获取WinRAR应用程序路径：通过注册表，获取exe路径；我的Win10是"SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\WinRAR.exe"。其他系统不知道有没有变化，可以自己打开注册表去检查下。
2. 创建Process类操作WinRAR应用程序：配置好ProcessStartInfo参数（在ProcessStartInfo参数中可以对Arguments 的赋值，传入RAR命令符）
3. RAR命令符说明：随意打开WinRAR后可以查看相应的命令符说明
   以下是封装的类
