以下代码在文件夹无空格时可压缩String the_rar;
        RegistryKey the_Reg;
        Object the_Obj;
        String the_Info;
        ProcessStartInfo the_StartInfo;
        Process the_Process;
        try
        {
            the_Reg = Registry.ClassesRoot.OpenSubKey(@"Applications\WinRAR.exe\Shell\Open\Command");
            the_Obj = the_Reg.GetValue("");
            the_rar = the_Obj.ToString();
            the_Reg.Close();
            the_rar = the_rar.Substring(1, the_rar.Length - 7);
            the_Info = " a " + " " + DRARName.ToString() + " " + DFilePath.ToString() + " -ep1"; //命令 + 压缩后文件名 + 被压缩的文件或者路径
            the_StartInfo = new ProcessStartInfo();
