用c#写windows服务 怎么写

Answer 1

1.创建Windows Service项目
从Visual C# 工程中选取 Windows 服务（Windows Service）选项，给工程一个新文件名，然后点击 确定。

2.向服务中函数功能实现
OnStart函数在启动服务时执行，OnStop函数在停止服务时执行。在这里，当启动和停止服务时，向一个文本文件中写入一些文字信息，代码如下:

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.Threading.Tasks;

namespace MyService
{
public partial class Service1 : ServiceBase
{
public Service1()
{
InitializeComponent();
}

protected override void OnStart(string[] args)
{
FileStream fs = new FileStream(@"d:\xx.txt", FileMode.OpenOrCreate, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);
sw.BaseStream.Seek(0, SeekOrigin.End);
sw.WriteLine("WindowsService: Service Started" + DateTime.Now.ToString() + "\n");

sw.Flush();
sw.Close();
fs.Close();
}

//protected override void OnContinue()
//{
// base.OnContinue();
//}

//protected override void OnPause()
//{
// base.OnPause(); // father class method inherit
//}

//protected override void OnShutdown()
//{
// base.OnShutdown();
//}

protected override void OnStop()
{
FileStream fs = new FileStream(@"d:\xx.txt", FileMode.OpenOrCreate, FileAccess.Write);
StreamWriter sw = new StreamWriter(fs);
sw.BaseStream.Seek(0, SeekOrigin.End);
sw.WriteLine("WindowsService: Service Stopped" + DateTime.Now.ToString() + "\n");
sw.Flush();
sw.Close();
fs.Close();

}
}
}

4.回到设计窗口点右键选择-添加安装程序 -生成serviceInstaller1和 serviceProcessInstaller1两个组件
把serviceInstaller1的属性ServiceName改写为你的服务程序名，并把启动模 式设置为AUTOMATIC
把serviceProcessInstaller1的属性account改写为 LocalSystem

5.编译链接生成服务程序
通过从生成菜单中选择生成来生成项目。

6.安装服务
用.net framework工具INSTALLUTIL安装服务程序即可。
用项目的输出作为参数，从命令行运行 InstallUtil.exe。在命令行中输入下列代码：
installutil yourproject.exe
Hint: a windows service must first be installed using installutil.exe and then started with the serviceExplorer, windows Services Administrative tool or the NET START command.

7.卸载服务
