c#之添加window服务(定时任务)

基础之上，

这篇文章主要讲述，使用winform程序来控制window服务的安装，启动，停止，卸载等操作

1.在同一个解决方案添加winform项目，如图

2.在winform设计器中添加按钮

修改按钮名称依次为：安装服务、启动服务、停止服务、卸载服务

3.向winform项目中添加引用：System.Configuration.Install 和 System.ServiceProcess 两个程序集(其中涉及window服务的一些操作)

4.把之前创建的window服务也引入winform中

5.编写代码

 public partial class Form1 : Form

    {

        public Form1()

        {

            InitializeComponent();

        }

        //安装及卸载路径

        string serviceFilePath = $"{Application.StartupPath}\\WindowService_HelloWorld.exe";

        //服务名称

        string serviceName = "MyService";

        /// <summary>

        /// 事件：安装服务

        /// </summary>

        /// <param name="sender"></param>

        /// <param name="e"></param>

        private void button1_Click(object sender, EventArgs e)

        {

            if (IsServiceExisted(serviceName)) this.UninstallService(serviceName);

            this.InstallService(serviceFilePath);

        }

        /// <summary>

        /// 事件：启动服务

        /// </summary>

        /// <param name="sender"></param>

        /// <param name="e"></param>

        private void button2_Click(object sender, EventArgs e)

        {

            if (IsServiceExisted(serviceName)) this.ServiceStart(serviceName);

        }

        /// <summary>

        /// 停止服务

        /// </summary>

        /// <param name="sender"></param>

        /// <param name="e"></param>

        private void button3_Click(object sender, EventArgs e)

        {

            if (IsServiceExisted(serviceName)) this.ServiceStop(serviceName);

        }

        /// <summary>

        /// 卸载服务

        /// </summary>

        /// <param name="sender"></param>

        /// <param name="e"></param>

        private void button4_Click(object sender, EventArgs e)

        {

            if (IsServiceExisted(serviceName))

            {

                this.ServiceStop(serviceName);

                this.UninstallService(serviceFilePath);

            }

        }

        /// <summary>

        /// 判断服务是否存在

        /// </summary>

        /// <param name="serviceName"></param>

        /// <returns></returns>

        private bool IsServiceExisted(string serviceName)

        {

            ServiceController[] services = ServiceController.GetServices();

            foreach(ServiceController sc in services)

            {

                if (sc.ServiceName.ToLower() == serviceName.ToLower())

                {

                    return true;

                }

            }

            return false;

        }

        /// <summary>

        /// 安装服务

        /// </summary>

        /// <param name="serviceFilePath"></param>

        private void InstallService(string serviceFilePath)

        {

            using(AssemblyInstaller installer=new AssemblyInstaller())

            {

                installer.UseNewContext = true;

                installer.Path = serviceFilePath;

                IDictionary saveState = new Hashtable();

                installer.Install(saveState);

                installer.Commit(saveState);

            }

        }

        /// <summary>

        /// 卸载服务

        /// </summary>

        /// <param name="serviceFilePath"></param>

        private void UninstallService(string serviceFilePath)

        {

            using(AssemblyInstaller installer=new AssemblyInstaller())

            {

                installer.UseNewContext = true;

                installer.Path = serviceFilePath;

                installer.Uninstall(null);

            }

        }

        /// <summary>

        /// 启动服务

        /// </summary>

        /// <param name="serviceName"></param>

        private void ServiceStart(string serviceName)

        {

            using(ServiceController controller=new ServiceController(serviceName))

            {

                if (controller.Status == ServiceControllerStatus.Stopped)

                {

                    controller.Start();

                }

            }

        }

        /// <summary>

        /// 停止服务

        /// </summary>

        /// <param name="serviceName"></param>

        private void ServiceStop(string serviceName)

        {

            using(ServiceController controller=new ServiceController(serviceName))

            {

                if (controller.Status == ServiceControllerStatus.Running)

                {

                    controller.Stop();

                }

            }

        }

    }

结构如下：

6.在项目winform中，右击项目，添加->新建项，在弹出的菜单中选择应用程序清单文件，如图

7.打开该文件，并将<requestedExecutionLevel level="asInvoker" uiAccess="false" />改为<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />，如下图所示：

8.重新生成解决方案，并运行(winform自己不知道自己是谁)

点击安装，打开window服务管理器，发现MyService安装上了，后续几个按钮依次实验，正常

另外还有一些调试技巧，这里就不多说了
