C#调用Rar文件及获取Rar返回值的方法

System.Diagnostics.Process process;private void btnRAR_Click(object sender, EventArgs e){ if (System.IO.File.Exists("Rar.exe")) {  try  {   process = new System.Diagnostics.Process();   process.StartInfo.FileName = "Rar.exe";   process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Minimized;   process.EnableRaisingEvents = true;   //m<0..5>  设置压缩级别(0-存储...3-默认...5-最大)   //rar a -m5 -ag[yyyy年mm月dd日_hh点mm分-ss] MyLuoLuo   process.StartInfo.Arguments = string.Format(@"a -m{0} -ag[yyyy年mm月dd日_hh点mm分-ss] {1}//MyLuoLuo.rar {2}", this.SaveRank.ToString(),this.FileName,this.RarPath); //@"a -m5 -ag[yyyy年mm月dd日_hh点mm分-ss] MyLuoLuo.rar D:/Txt";   process.Exited += new EventHandler(RarStop);   process.Start();  }  catch (Exception ex)  {   MessageBox.ShowError("发生错误!错误信息:/n" + ex.Message);  } }}

private void RarStop(object sender, System.EventArgs e){ switch (process.ExitCode) {  case 0:   MessageBox.ShowInformation("压缩成功！");   break;  case 1:   MessageBox.ShowInformation("有错误但没有发生致命错误！");   break;  case 2:   MessageBox.ShowError("发生一个致命错误！");   break;  case 3:   MessageBox.ShowError("解压缩时发生一个 CRC 错误！");   break;  case 4:   MessageBox.ShowError("试图修改先前使用 'k' 命令锁定的压缩文件！");   break;  case 5:   MessageBox.ShowError("写入磁盘错误！");   break;  case 6:   MessageBox.ShowError("打开文件错误！");   break;  case 7:   MessageBox.ShowError("命令行选项错误！");   break;  case 8:   MessageBox.ShowError("没有足够的内存进行操作！");   break;  case 9:   MessageBox.ShowError("创建文件错误！");   break;  case 255:   MessageBox.ShowError("用户中断操作");   break;  default:   MessageBox.ShowError("未知错误！");   break; }}
