在unity中，StartCoroutine不能在process.Exited中工作

using UnityEngine;
using System.Diagnostics;

public class MyScript : MonoBehaviour
{
    private Process externalProcess;

    private void Start()
    {
        externalProcess = new Process();
        externalProcess.StartInfo.FileName = "your_external_process.exe";
        externalProcess.Exited += OnProcessExited;

        externalProcess.Start();

        // 等待进程退出后再执行协程
        StartCoroutine(WaitForProcessExit());
    }

    private void OnProcessExited(object sender, System.EventArgs e)
    {
        // 外部进程已退出
    }

    private System.Collections.IEnumerator WaitForProcessExit()
    {
        while (!externalProcess.HasExited)
        {
            yield return null;
        }

        // 执行协程相关的操作
    }
}

using UnityEngine;
using System.Diagnostics;
using System.Threading.Tasks;

public class MyScript : MonoBehaviour
{
    private Process externalProcess;

    private void Start()
    {
        externalProcess = new Process();
        externalProcess.StartInfo.FileName = "your_external_process.exe";
        externalProcess.Exited += OnProcessExited;

        externalProcess.Start();

        // 启动一个异步任务来监控进程状态
        Task.Run(() => MonitorProcessStatus());
    }

    private void OnProcessExited(object sender, System.EventArgs e)
    {
        // 外部进程已退出
        // 执行相应的操作
    }

    private async Task MonitorProcessStatus()
    {
        await Task.Delay(100); // 等待一段时间，确保进程已经启动

        while (!externalProcess.HasExited)
        {
            await Task.Delay(100); // 每隔一段时间检查一次进程状态
        }

        // 进程已退出
        // 执行相应的操作
    }
}
