Unity3D C#打开外部应用程序，并检测应用程序是否关闭退出实现代码：

using UnityEngine;
using System.Collections;
using System.Diagnostics;
using System;
 
public class StartOtherApp : MonoBehaviour {
 
    private Process pc;
    void Start () {
        StartCoroutine(StartApp());
    }
 
    IEnumerator StartApp()
    {
        yield return new WaitForSeconds(2);
        pc = Process.Start(\"C:/Users/Lee/Desktop/Flash VideoPlayer/VRPlayer/VRPlayer.app/VRPlayer.exe\");
 
        pc.EnableRaisingEvents = true;
        pc.Exited += new EventHandler(myProcess_Exited);
    }
 
    void myProcess_Exited(object sender, EventArgs e)
    {
        Application.Quit();
    }
}
