Unity与外部exe交互

个人插眼学习：
1.打开关闭exe程序

using UnityEngine;
using System.Collections;
using System.Diagnostics;
using System.Collections.Generic;
using System;
 
public class CallApplication : MonoBehaviour
{
 
    // Use this for initialization
    private static string outputPath = @"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe";
    private int x = 0, y = 0;
    private bool isOn = false;
    private int minute = 0;
 
    // Use this for initialization
    void Start()
    {
        //ListAllAppliction();
        UnityEngine.Debug.Log("当前应用：" + Process.GetCurrentProcess().ProcessName + " 进程ID: " + Process.GetCurrentProcess().Id);
    }
    void OnGUI()
    {
        if (GUI.Button(new Rect(10, 10, 200, 50), "打开外部应用"))
        {
            if (CheckProcess("chrome"))
                return;
            else
                StartProcess(outputPath);
        }
        if (GUI.Button(new Rect(10, 60, 200, 50), "杀死应用进程"))
        {
            KillProcess("chrome");
        }
        if (GUI.Button(new Rect(10, 110, 200, 50), "开启定时关闭"))
        {
            minute = System.DateTime.Now.Minute + 1;
            isOn = true;
        }
        if (isOn)
        {
            GUI.contentColor = Color.red;
            GUI.Label(new Rect(10, 160, 160, 30), "\t倒计时:" + (60 - System.DateTime.Now.Second));
            if (System.DateTime.Now.Minute == minute)
            {
                UnityEngine.Debug.Log("自动关闭应用....");
                KillProcess("chrome");
                isOn = false;
            }
        }
    }
    ///

        foo.Start();
    }
 
    ///
