C#创建windows服务

一、创建一个Windows Service

1.新建项目 Windows服务

 

2.服务命名，进入编辑

贴代码

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 AirLogService
{
    public partial class AirLogService : ServiceBase
    {
        /// <summary>
        /// Init
        /// </summary>
        public AirLogService()
        {
            InitializeComponent();
        }

        /// <summary>
        /// 操作日志
        /// </summary>
        string filePath = @"D:AirLogServiceLog.txt";

        /// <summary>
        /// 启动
        /// </summary>
        /// <param name="args"></param>
        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！");
            }
            this.Do();
        }

        /// <summary>
        /// 停止
        /// </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！");
            }
        }

        private void Do()
        {
        }
    }
}

3.双击项目“MyWindowsService”进入“MyService”设计界面，在空白位置右击鼠标弹出上下文菜单，选中“添加安装程序”

 

4.点击“serviceInstaller1”，修改属性

这里的“ServiceName”将来会做为服务的唯一名称

5.点击“serviceProcessInstaller1”，在“属性”窗体将Account改为LocalSystem（服务属性系统级别）

二、创建安装、启动、停止、卸载服务的Windows窗体

1.新建一个Windows Form项目

2.在窗体内添加四个按钮，分别为安装服务、启动服务、停止服务及卸载服务

 

3.添加引用“System.ServiceProcess”及“System.Configuration.Install”

4.贴代码，窗体控制程序的代码

using System;
using System.Collections;
using System.Windows.Forms;
using System.ServiceProcess;
using System.Configuration.Install;

namespace AirServiceForm
{
    public partial class AirServiceForm : Form
    {
        /// <summary>
        /// 关联服务文件
        /// </summary>
        string serviceFilePath = $"{Application.StartupPath}\AirLogService.exe";
        /// <summary>
        /// 服务名
        /// </summary>
        string serviceName = "AirLogService";

        /// <summary>
        /// Init
        /// </summary>
        public AirServiceForm()
        {
            InitializeComponent();

            if (this.IsServiceExisted(serviceName))
            {
                this.btnInstall.Enabled = false;
                this.btnUnInstall.Enabled = true;
                if (this.IsServiceStarted(serviceName))
                {
                    this.btnStart.Enabled = false;
                    this.btnStop.Enabled = true;
                }
                else
                {
                    this.btnStart.Enabled = true;
                    this.btnStop.Enabled = false;
                }
            }
            else
            {
                this.btnInstall.Enabled = true;
                this.btnUnInstall.Enabled = false;
                this.btnStart.Enabled = false;
                this.btnStop.Enabled = false;
            }
        }

        /// <summary>
        /// 安装 按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnInstall_Click(object sender, EventArgs e)
        {
            if (!this.IsServiceExisted(serviceName))
            {
                this.btnInstall.Enabled = false;
                this.btnUnInstall.Enabled = true;
                this.btnStart.Enabled = true;
                this.InstallService(serviceFilePath);
            }
        }

        /// <summary>
        /// 启动 按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnStart_Click(object sender, EventArgs e)
        {
            if (this.IsServiceExisted(serviceName))
            {
                this.btnStart.Enabled = false;
                this.btnStop.Enabled = true;
                this.ServiceStart(serviceName);
            }
        }

        /// <summary>
        /// 暂停 按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnStop_Click(object sender, EventArgs e)
        {
            if (this.IsServiceExisted(serviceName))
            {
                this.btnStart.Enabled = true;
                this.btnStop.Enabled = false;
                this.ServiceStop(serviceName);
            }
        }

        /// <summary>
        /// 卸载 按钮
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void btnUnInstall_Click(object sender, EventArgs e)
        {
            if (this.IsServiceExisted(serviceName))
            {
                this.btnInstall.Enabled = true;
                this.btnUnInstall.Enabled = false;
                this.btnStart.Enabled = false;
                this.btnStop.Enabled = false;
                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>
        /// 判断服务是否启动
        /// </summary>
        /// <param name="serviceName"></param>
        /// <returns></returns>
        private bool IsServiceStarted(string serviceName)
        {
            using (ServiceController control = new ServiceController(serviceName))
            {
                if (control.Status == ServiceControllerStatus.Running)
                {
                    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 savedState = new Hashtable();
                installer.Install(savedState);
                installer.Commit(savedState);
            }
        }

        /// <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 control = new ServiceController(serviceName))
            {
                if (control.Status == ServiceControllerStatus.Stopped)
                {
                    control.Start();
                }
            }
        }

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

5.将已生成的MyWindowsService.exe引用到本Windows窗体

6.由于需要安装服务，故需要使用UAC中Administrator的权限

7.将<requestedExecutionLevel level="asInvoker" uiAccess="false" />改为<requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />

8.IDE启动后，将会弹出如下所示的窗体（有的系统因UAC配置有可能不显示），需要用管理员权限打开

 三、调试

1.界面操作服务，同时打开服务列表进行监控（services.msc）

2.点击安装之后，就会有服务了

四、运行调试

同调试iis进程w3wp类似，直接附加到进程即可
