Windows服务安装与控制

 

1、建立服务

  (1)定义一个ServiceInstaller

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace WindowService
{
    [System.ComponentModel.RunInstaller(true)]
    public class ServiceInstaller : System.Configuration.Install.Installer
    {
        System.ServiceProcess.ServiceProcessInstaller processInstaller;
        System.ServiceProcess.ServiceInstaller serviceInstaller;
        public ServiceInstaller()
        {
            processInstaller = new System.ServiceProcess.ServiceProcessInstaller();
            processInstaller.Account = System.ServiceProcess.ServiceAccount.LocalSystem;
            Installers.Add(processInstaller);

            serviceInstaller = new System.ServiceProcess.ServiceInstaller();
            serviceInstaller.DisplayName = "000000000";
            serviceInstaller.ServiceName = "000000000";
            serviceInstaller.StartType = System.ServiceProcess.ServiceStartMode.Automatic;
            
            Installers.Add(serviceInstaller);
        }
        protected override void OnAfterInstall(System.Collections.IDictionary savedState)
        {
            base.OnAfterInstall(savedState);

        }
    }
}

(2)定义一个服务

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Diagnostics;
using System.Linq;
using System.ServiceProcess;
using System.Text;

namespace WindowService
{
    partial class Service : ServiceBase
    {
        public Service()
        {
            InitializeComponent();
        }
        
        protected override void OnStart(string[] args)
        {
            
            // TODO:  在此处添加代码以启动服务。
        }

        protected override void OnStop()
        {
            // TODO:  在此处添加代码以执行停止服务所需的关闭操作。
        }
    }
}

(3)定义自己的安装方式:

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Reflection;
using System.Text;

namespace WindowService
{
    public class ServiceMaster
    {
        static string appPath = Assembly.GetExecutingAssembly().Location;
        public static void Main(string[] args)
        {
            if (args != null && args.Length > 0)
            {
                if (args[0] == "-i")
                {
                    InstallService();
                }
                else if (args[0] == "-u")
                {
                    UninstallService();
                }

            }
            else
            {
                var s = new Service() { ServiceName = "aaaaa" };
                Service.Run(s);
            }
        }
        public static void InstallService()
        {
            System.Configuration.Install.ManagedInstallerClass.InstallHelper(new string[] { appPath });
        }

        public static void UninstallService()
        {
            System.Configuration.Install.ManagedInstallerClass.InstallHelper(new string[] { "-u", appPath });
        }
    }
}

安装时,使用管理员权限运行cmd,输入程序带参数”-i”执行即可安装。这是使用的ManagedInstallerClass类的安装。接下来对上面这个服务使用另一种安装方式。

 

2、Windows Api安装方式。

(1)辅助类的设计

using System;
using System.ComponentModel;
using System.Runtime.ConstrainedExecution;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading;

namespace Yihe.Service
{
    #region 异常定义

    /// 服务不存在异常
    /// </summary>
    public class ServiceNotExistException : ApplicationException

        public ServiceNotExistException() : base("服务不存在!") { }

        public ServiceNotExistException(string message) : base(message) { }
    }

    #endregion

    #region 枚举定义

    /// <summary>

    }

    /// <summary>

    public enum ServiceAccount

    }

    #endregion

            }
            finally
