首先

一、创建Windows服务

修改项目名称

重命名Service名称

右键在空白区域点击 添加安装程序

此时软件会生成两个组件，分别为“serviceInstaller1”及“serviceProcessInstaller1”，如下图所示：

首先设置serviceProcessInstaller1 User改为LocalSystem

点击“servicestaller1”，在“属性”窗体将ServiceName改为MyService，Description改为我的服务，StartType保持为Manual，如下图所示：

F7进入代码编辑页面 Service页面 编辑好生成一下

code

public partial class MyService : ServiceBase
{
	public MyService()
    {
        InitializeComponent();
    }
    /// <summary>
    /// 开始服务
    /// </summary>
    string filePath = @"E:\MyServiceLog.txt";

    protected override void OnStart(string[] args)
    {
        using (FileStream stream = new FileStream(filePath, FileMode.Append))
        using (StreamWriter writer = new StreamWriter(stream))
        {
            writer.WriteLine($"{DateTime.Now},服务启动！");
        }
        System.Timers.Timer timer = new System.Timers.Timer();
        timer.Elapsed += new System.Timers.ElapsedEventHandler(TimedEvent);//每隔自定的间隔时间就会触发一次事件，若不暂停将无限循环触发，相当于一个计时器。
        timer.Interval = 1000 * 5;     //每5秒执行一次
        timer.Enabled = true;           //是否启用
    }

    private void TimedEvent(object sender, System.Timers.ElapsedEventArgs e)
    {
        Task.Run(() =>
        {
            //封装好的方法
            GetAllOrder getAllOrder = new GetAllOrder();
            getAllOrder.GetAll();
        });
    }
    /// <summary>
    /// 停止服务
    /// </summary>
    protected override void OnStop()
    {
        using (FileStream stream = new FileStream(filePath, FileMode.Append))
        using (StreamWriter writer = new StreamWriter(stream))
        {
            writer.WriteLine($"{DateTime.Now},服务停止！");
        }
    }
}

在bin根目录文件夹下会出现 MyWindowsService.exe文件

在MyWindowsService的App.config里设置数据库链接

二、创建安装、启动、停止、卸载服务的Windows窗体

在WinForm应用程序添加新建项 添加应用程序清单文件app.manifest

设置app.manifest 把level="asInvoker"设置成level="requireAdministrator"

设置控件

F7进入代码编辑页面

code

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    string serviceFilePath = $"{AppDomain.CurrentDomain.BaseDirectory}\\MyWindowsService.exe";
    string serviceName = "MyService";

    //事件:安装服务
    private void Install_Click(object sender, EventArgs e)
    {
        if (this.IsServiceExisted(serviceName)) this.UninstallService(serviceFilePath);
        this.InstallService(serviceFilePath);
    }

    //事件:启动服务
    private void StartUp_Click(object sender, EventArgs e)
    {
        if (this.IsServiceExisted(serviceName)) this.ServiceStart(serviceName);
    }

    //事件:停止服务
    private void StopOff_Click(object sender, EventArgs e)
    {
        if (this.IsServiceExisted(serviceName)) this.ServiceStop(serviceName);
    }

    //事件:卸载服务
    private void UnInstall_Click(object sender, EventArgs e)
    {
        if (this.IsServiceExisted(serviceName))
        {
            this.ServiceStop(serviceName);
            this.UninstallService(serviceFilePath);
        }
    }

    //判断服务是否存在
    private bool IsServiceExisted(string serviceName)
    {
        ServiceController[] services = ServiceController.GetServices();
        foreach (ServiceController sc in services)
        {
            if (sc.ServiceName.ToLower() == serviceName.ToLower())
            {
                return true;
            }
        }
        return false;
    }

    //安装服务
    private void InstallService(string serviceFilePath)
    {
        using (AssemblyInstaller installer = new AssemblyInstaller())
        {
            installer.UseNewContext = true;
            installer.Path = serviceFilePath;
            IDictionary savedState = new Hashtable();
            installer.Install(savedState);
            installer.Commit(savedState);
        }
    }

    //卸载服务
    private void UninstallService(string serviceFilePath)
    {
        using (AssemblyInstaller installer = new AssemblyInstaller())
        {
            installer.UseNewContext = true;
            installer.Path = serviceFilePath;
            installer.Uninstall(null);
        }
    }
    //启动服务
    private void ServiceStart(string serviceName)
    {
        using (ServiceController control = new ServiceController(serviceName))
        {
            if (control.Status == ServiceControllerStatus.Stopped)
            {
                control.Start();
            }
        }
    }

    //停止服务
    private void ServiceStop(string serviceName)
    {
        using (ServiceController control = new ServiceController(serviceName))
        {
            if (control.Status == ServiceControllerStatus.Running)
            {
                control.Stop();
            }
        }
    }
}

引用我们要执行的服务

使用WIN+R的方式打开运行窗体，并在窗体内输入services.msc后打开服务，如下图所示：

点击窗体内的“安装服务”按钮，将会在服务中出现MyService，如下图所示：

点击“运行服务”按钮，将启动并运行服务，如下所示：
