Question

C# 编写的windows service, 安装正常， 就是不能启动

using System;

using System.Collections.Generic;

using System.ComponentModel;
using System.Data;

using System.Diagnostics;

using System.IO;

using System.Linq;

using System.ServiceProcess;

using System.Text;

using System.Timers;

using System.Runtime.InteropServices;

namespace Protecter

{

public partial class Service1 : ServiceBase

{

public Service1()

{

InitializeComponent();

}

protected override void OnStart(string[] args)

{

writeStartTime();

Timer runningTimer = new Timer();

runningTimer.Elapsed += new ElapsedEventHandler(writeRunningTime);

runningTimer.Interval = 5000;

runningTimer.Enabled = true;

GC.KeepAlive(runningTimer);

}

protected override void OnStop()

{

}

private void writeStartTime()

{

string logPath = @"C:\EthanCui\protecter.txt";

FileStream logStream = File.Open(logPath, FileMode.Append, FileAccess.ReadWrite);

StreamWriter logStreamWriter = new StreamWriter(logStream, Encoding.GetEncoding("gb2312"));

DateTime startTime = DateTime.UtcNow;

logStreamWriter.Write("Start at:" + startTime.ToString());

logStreamWriter.Close();

logStream.Close();

}

private static void writeRunningTime(object source, ElapsedEventArgs e)

{

string logPath = @"C:\EthanCui\protecter.txt";

FileStream logStream = File.Open(logPath, FileMode.Append, FileAccess.ReadWrite);

StreamWriter logStreamWriter = new StreamWriter(logStream, Encoding.GetEncoding("gb2312"));

DateTime startTime = DateTime.UtcNow;

logStreamWriter.Write("Running at:" + startTime.ToString());

logStreamWriter.Close();

logStream.Close();

}

}

}
我把OnStart() 里面的代码删掉，发现可以启动了，在网上搜，有人说启动方法里面的代码执行如果时间太长就会报错。那我应该怎么调整代码呢，我就是想每隔五秒钟，就将当前日期时间写入log文件中。

Answer 1

请检查一下writeStartTime();这个方法 ；

还有GC.KeepAlive(runningTimer);

大概是writeStartTime(); 方法引起的
加上日志 ，看看是否执行了此方法

Answer 2

看看错误日志，如果没有 把错误日志输出来，看下具体什么错误才能调试。

追问

没有使用event log，小白第一次写服务，能安装，启动不了好像不能调试吧
