windows服务开发

学然后知不足 教然后知困。

没做过windows service开发时，感觉很难，无从下手。再网看了些例子，加上自己的理解，写下开发步骤。

开发步骤

1. 新建windows service
   

2. 添加服务，发表后将再自己的电脑的 服务管理 查看到
   

    partial class MyService : ServiceBase
    {
        Timer timer1;

        public MyService()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            // TODO: Add code here to start your service.

            using (StreamWriter sw = File.AppendText(@"D:\\log2.txt"))
            {
                sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + " Start.");
            }

            timer1 = new Timer();
            timer1.Interval = 2000;
            timer1.Elapsed += (sender, e) =>
            {
                using (StreamWriter sw = File.AppendText(@"D:\\log2.txt"))
                {
                    sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + " Countue...");
                }
            };
            timer1.Start();
        }

        protected override void OnStop()
        {
            // TODO: Add code here to perform any tear-down necessary to stop your service.
            using (StreamWriter sw = File.AppendText(@"D:\\log2.txt"))
            {
                sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + " Stop.");
            }
        }
    }

1. 添加服务安装程序（这是vs给提供的方便操作），可以发表多个服务。
   

右击，点击Add Installer，自动生成类ProjectInstaller。大家可以看下vs自动生成的类ProjectInstaller.Designer.cs文件

private void InitializeComponent()
        {
            this.serviceProcessInstaller1 = new System.ServiceProcess.ServiceProcessInstaller();
            this.serviceInstaller1 = new System.ServiceProcess.ServiceInstaller();
            //设置服务安装信息
            this.serviceProcessInstaller1.Account = System.ServiceProcess.ServiceAccount.LocalService;
            this.serviceProcessInstaller1.Password = null;
            this.serviceProcessInstaller1.Username = null;
            //要安装的服务（保证与你的服务名一致，可添加多个）
            this.serviceInstaller1.ServiceName = "MyService";
            //服务加入
            this.Installers.AddRange(new System.Configuration.Install.Installer[] {
            this.serviceProcessInstaller1,
            this.serviceInstaller1});

        }

注意将服务安装设置为:手动安装

1. 服务安装卸载脚本
   Install.bat 文件：

   %SystemRoot%\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe "%~dp0%WindowsServiceTest.exe"
   pause

   Uninstall.bat文件：

   %SystemRoot%\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe -u "%~dp0%WindowsServiceTest.exe"
   pause
