C#调用winrar进行解压缩 求助！

Question

我用c#调用winrar进行解压缩，然后winrar提示诊断错误：对于 ZIP 压缩文件来说文件尺寸太大了。使用 RAR 代替代码是：
public string Unrar(string unZipPath,string strzipPath)
        {
            Process Process1 = new Process();
          //解压缩后文件保存的路径
             //解压的文件
            //启动进程并调用Winrar  
            Process1.StartInfo.FileName = "WinRAR.exe";
            Process1.StartInfo.CreateNoWindow = true;
            Process1.StartInfo.Arguments = " a -r " + unZipPath + " " + strzipPath;
            Process1.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; //隐藏压缩窗口
            Process1.Start();
            Process1.WaitForExit();
            Process1.Close();
            return unZipPath;
        }
        

Answer 1

有没人知道  C++ 带命令行调用EXE 的代码怎么写？

Answer 2

是winrar提示的错误么？你确认Process1.StartInfo.FileName = "WinRAR.exe";相对路径就调用成功了？

Answer 3

谢谢大家了，参数写错了呵呵" a -r "是压缩， " e -y "是解压缩
