求助,为何我的程序无法自动运行关闭系统服务的指令

Question

public void callApp(string filename)
{
    ServiceController service = new ServiceController("Pronto Data Server");
    if (service.Status.Equals(ServiceControllerStatus.Stopped))
    {
        service.Start();
        service.WaitForStatus(ServiceControllerStatus.Running);
    }
    Process process = new Process();
    process.StartInfo.FileName = filename;
    process.Start();
    while (process.HasExited)
    {
        service.Stop();
        service.WaitForStatus(ServiceControllerStatus.Stopped);
        Environment.Exit(0);
    }
}在程序中调用了以上的方法,服务及外部程序及执行成功,就是While循环里的语句在DEBUG时可执行,到真正应用起码却并没有执行,请问各位是什么问题呢?

完整的代码如下using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using System.IO;
using System.ServiceProcess;
using System.Threading;namespace ProntoDataServerCall
{
    public partial class Form1 : Form
    {
        public string filename="ProntoEdit Professional 2.0.exe";
        public Form1()
        {
            InitializeComponent();
            FileInfo file = new FileInfo(filename);
            if (!file.Exists)
            {
                MessageBox.Show("Plesse locate the file", "Tips", MessageBoxButtons.OK);
                openFileDialog1.ShowDialog();
                filename = openFileDialog1.FileNames[0];
                if (filename.Contains("ProntoEdit Professional"))
                {
                    try
                    {
                        openFileDialog1.OpenFile();
                        callApp(filename);
                    }
                    catch
                    {
                        Environment.Exit(0);
                    }
                }
            }
            else
                callApp(filename);
            
        }
        public void callApp(string filename)
        {
            ServiceController service = new ServiceController("Pronto Data Server");
            if (service.Status.Equals(ServiceControllerStatus.Stopped))
            {
                service.Start();
                service.WaitForStatus(ServiceControllerStatus.Running);
            }
            Process process = new Process();
            process.StartInfo.FileName = filename;
            process.Start();
            while (process.HasExited)
            {
                service.Stop();
                service.WaitForStatus(ServiceControllerStatus.Stopped);
                Environment.Exit(0);
            }
        }
    }
}

WHILE语句重新修改了一下就OK了
while (true)
{
    if(process.HasExited)
    {
        service.Stop();
        service.WaitForStatus(ServiceControllerStatus.Stopped);
        Environment.Exit(0);
    }
    else
    {
        Thread.Sleep(2000);
    }
}
