使用winform程序控制window服务的操作

继上篇

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：
