Unity3D启动外部程序并传递参数的实现

public void StartEXE()
    {
        ProcessStartInfo processStartInfo = new ProcessStartInfo();
        processStartInfo.FileName = "C:/Users/Administrator/Desktop/Test/Demo.exe";
        processStartInfo.Arguments = "启动 程序 1 2  3";
        Process.Start(processStartInfo);
    }

private void Start()
    {
        string[] args = Environment.GetCommandLineArgs();
        text.text = args.Length.ToString();
        for (int i = 0; i < args.Length; i++)
        {
            text.text += "\n" + "Arg" + i + ":  " + args[i];
        }
    }
