C# 编写Windows Service（windows服务程序）
- Windows Service简介:
一个Windows服务程序是在Windows操作系统下能完成特定功能的可执行的应用程序。Windows服务程序虽然是可执行的，但是它不像一般的可执行文件通过双击就能开始运行了，它必须有特定的启动方式。这些启动方式包括了自动启动和手动启动两种。对于自动启动的Windows服务程序，它们在Windows启动或是重启之后用户登录之前就开始执行了。只要你将相应的Windows服务程序注册到服务控制管理器（Service Control Manager）中，并将其启动类别设为自动启动就行了。而对于手动启动的Windows服务程序，你可以通过命令行工具的NET START 命令来启动它，或是通过控制面板中管理工具下的服务一项来启动相应的Windows服务程序。
同样，一个Windows服务程序也不能像一般的应用程序那样被终止。因为Windows服务程序一般是没有用户界面的，所以你也要通过命令行工具或是下面图中的工具来停止它，或是在系统关闭时使得Windows服务程序自动停止。因为Windows服务程序没有用户界面，所以基于用户界面的API函数对其是没有多大的意义。为了能使一个Windows服务程序能够正常并有效的在系统环境下工作，程序员必须实现一系列的方法来完成其服务功能。Windows服务程序的应用范围很广，典型的Windows服务程序包含了硬件控制、应用程序监视、系统级应用、诊断、报告、Web和文件系统服务等功能。
和Windows服务程序相关的命名空间涉及到以下两个：System.ServiceProcess 和System.Diagnostics。
- 用C#创建Windows服务的步骤:
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
用项目的输出作为参数，从命令行运行 InstallUtil.exe。
installutil /u yourproject.exe
如上服务程序运行结果截图：
- 补充：
1.Service启动属性：
Manual 服务安装后，必须手动启动。
Automatic 每次计算机重新启动时，服务都会自动启动。
Disabled 服务无法启动。
2.新建的Service项目，其中各属性的含义（设计视图->右键属性）：
Autolog 是否自动写入系统的日志文件
CanHandlePowerEvent 服务时候接受电源事件
CanPauseAndContinue 服务是否接受暂停或继续运行的请求
CanShutdown 服务是否在运行它的计算机关闭时收到通知，以便能够调用 OnShutDown 过程
CanStop 服务是否接受停止运行的请求
ServiceName 服务名
3. 也可以在系统服务管理器中，设置相应Service的属性或启动方式等
计算机管理 -> 服务和应用程序 -> 服务 -> ...
给WINDOWS服务加上描述
当我们创建一个WINDOWS服务后，却发觉我们所创建的服务没有相关的描述。（你可以打开服务管理器程序查看）。而System.ServiceProcess.ServiceBase这些相关的类都没有提供这方面的信息。同样如果我们需要给我们的服务加上恰当的描述，我们也只能通过非托管代码来处理。

}
}在安装完成后，我们对服务进行。这里可以修改的内容包括服务的描述，服务的故障处理等.
如果你在安装时，需要对服务进行自动处于运行状态，或卸载时需要自动将服务也卸载，你只要注册
this.BeforeUninstall+=new InstallEventHandler(ProjectInstaller_BeforeUninstall);
this.Committed+=new InstallEventHandler(ProjectInstaller_Committed);这二个事件
Committed事件，在这里可以将安装的服务进行调整到运行状态
BeforeUninstall事件，您可以在这里将服务自动卸载掉
