使用C#执行bat文件和结束某个端口号

1级标题

启动bat

    private string _start; //bat路径
    private void Awake()
    {
        _start = @"C:\test\test.bat";
        RunBat(_start);
    }
    //启动bat
    public void RunBat(string filename)
    {
       
        Process pro = new Process();
        FileInfo file = new FileInfo(filename);
        pro.StartInfo.WorkingDirectory = file.Directory.FullName;
        pro.StartInfo.FileName = filename;
        pro.StartInfo.CreateNoWindow = false;
        //pro.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;  //隐藏启动窗口
        pro.Start();
        //pro.WaitForExit();  //等待启动完毕离开
    }

    //结束端口号的占用
