c#创建windows服务

任务:本例中我们做一个定时向本地文件写记录的功能。 

一、创建windows服务

创建成功后如图:

右键点击Service1.cs查看代码

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 MyFirstWindowsService
{
    public partial class Service1 : ServiceBase
    {
        public Service1()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
        }

        protected override void OnStop()
        {
        }
    }
}

  三、添加一个FileOperation类文件

四、编写代码到File Operation类

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

namespace MyFirstWindowsService
{
    public class FileOpetation
    {
        /// <summary>
        /// 保存至本地文件
        /// </summary>
        /// <param name="ETMID"></param>
        /// <param name="content"></param>
        public static void SaveRecord(string content)
        {
            if (string.IsNullOrEmpty(content))
            {
                return;
            }

            FileStream fileStream = null;

            StreamWriter streamWriter = null;

            try
            {
                string path = Path.Combine(System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase, string.Format("{0:yyyyMMdd}", DateTime.Now));

                using (fileStream = new FileStream(path, FileMode.Append, FileAccess.Write))
                {
                    using (streamWriter = new StreamWriter(fileStream))
                    {
                        streamWriter.Write(content);

                        if (streamWriter != null)
                        {
                            streamWriter.Close();
                        }
                    }

                    if (fileStream != null)
                    {
                        fileStream.Close();
                    }
                }
            }
            catch { }
        }
    }
}

  五、在Service.cs类中调用代码

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

namespace MyFirstWindowsService
{
    public partial class Service1 : ServiceBase
    {
        System.Threading.Timer recordTimer;

        public Service1()
        {
            InitializeComponent();
        }

        protected override void OnStart(string[] args)
        {
            IntialSaveRecord();
        }

        protected override void OnStop()
        {
            if (recordTimer != null)
            {
                recordTimer.Dispose();
            }
        }

        private void IntialSaveRecord()
        {
            TimerCallback timerCallback = new TimerCallback(CallbackTask);

            AutoResetEvent autoEvent = new AutoResetEvent(false);

            recordTimer = new System.Threading.Timer(timerCallback, autoEvent, 10000, 60000 * 10);
        }

        private void CallbackTask(Object stateInfo)
        {
            FileOpetation.SaveRecord(string.Format(@"当前记录时间:{0},状况:程序运行正常!", DateTime.Now));
        }
    }
}

  六、右键点击添加安装程序

七、右键serviceInstaller1点属性

八,同理,右键serviceProcessInstaller1点属性

这样一个服务就写好了,剩下的就是如何把服务添加到windows服务中。后面就是用代码实现把服务添加到windows服务中。

1)上面写好的服务会在..\Service\MyFirstWindowsService\MyFirstWindowsService\bin\Debug生成

安装程序安装时需要用到这个exe的路径,所以方便起见,将这个生成的exe文件拷贝至安装程序的运行目录下

把exe文件复制在安装程序的bin\Debug下:如..\Service\MyInstallFirstWindowsService\MyInstallFirstWindowsService\bin\Debug

2)新建一个控制台应用程序

3)添加下图两个引用和应用程序配置文件

4)在app.config中添加如下代码

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup useLegacyV2RuntimeActivationPolicy="true">
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
    </startup>
</configuration>

  5)最后在Program.cs中添加安装代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;
using System.Threading;
using System.IO;
using System.Windows.Forms;
using System.ServiceProcess;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Application.EnableVisualStyles();

            Application.SetCompatibleTextRenderingDefault(false);

            string sysDisk = System.Environment.SystemDirectory.Substring(0, 3);

            string dotNetPath = sysDisk + @"WINDOWS\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe";//因为当前用的是4.0的环境

            string serviceEXEPath = Application.StartupPath + @"\MyFirstWindowsService.exe";//把服务的exe程序拷贝到了当前运行目录下,所以用此路径

            string serviceInstallCommand = string.Format(@"{0}  {1}", dotNetPath, serviceEXEPath);//安装服务时使用的dos命令

            string serviceUninstallCommand = string.Format(@"{0} -U {1}", dotNetPath, serviceEXEPath);//卸载服务时使用的dos命令

            try
            {
                if (File.Exists(dotNetPath))
                {
                    string[] cmd = new string[] { serviceUninstallCommand };


                    string ss = Cmd(cmd);

                    CloseProcess("cmd.exe");
                }

            }
            catch
            {
            }

            Thread.Sleep(1000);

            try
            {
                if (File.Exists(dotNetPath))
                {
                    string[] cmd = new string[] { serviceInstallCommand };

                    string ss = Cmd(cmd);

                    CloseProcess("cmd.exe");
                }

            }
            catch
            {

            }

            try
            {
                Thread.Sleep(3000);

                ServiceController sc = new ServiceController("MyFirstWindowsService");

                if (sc != null && (sc.Status.Equals(ServiceControllerStatus.Stopped)) ||

                          (sc.Status.Equals(ServiceControllerStatus.StopPending)))
                {
                    sc.Start();
                }
                sc.Refresh();
            }
            catch
            {
            }
        }

        /// <summary>
        /// 运行CMD命令
        /// </summary>
        /// <param name="cmd">命令</param>
        /// <returns></returns>
        public static string Cmd(string[] cmd)
        {
            Process p = new Process();
            p.StartInfo.FileName = "cmd.exe";
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true;
            p.Start();
            p.StandardInput.AutoFlush = true;
            for (int i = 0; i < cmd.Length; i++)
            {
                p.StandardInput.WriteLine(cmd[i].ToString());
            }
            p.StandardInput.WriteLine("exit");
            string strRst = p.StandardOutput.ReadToEnd();
            p.WaitForExit();
            p.Close();
            return strRst;
        }

        /// <summary>
        /// 关闭进程
        /// </summary>
        /// <param name="ProcName">进程名称</param>
        /// <returns></returns>
        public static bool CloseProcess(string ProcName)
        {
            bool result = false;
            System.Collections.ArrayList procList = new System.Collections.ArrayList();
            string tempName = "";
            int begpos;
            int endpos;
            foreach (System.Diagnostics.Process thisProc in System.Diagnostics.Process.GetProcesses())
            {
                tempName = thisProc.ToString();
                begpos = tempName.IndexOf("(") + 1;
                endpos = tempName.IndexOf(")");
                tempName = tempName.Substring(begpos, endpos - begpos);
                procList.Add(tempName);
                if (tempName == ProcName)
                {
                    if (!thisProc.CloseMainWindow())
                        thisProc.Kill(); // 当发送关闭窗口命令无效时强行结束进程
                    result = true;
                }
            }
            return result;
        }
    }
}

  

直接运行程序,运行完成后;

除了代码添加windows服务外,也可以用管理员的身份运行Visual Studio 命令提示(2010),

安装输入:installutil  ..\Service\MyFirstWindowsService\MyFirstWindowsService\bin\Debug\MyFirstWindowsService.exe

卸载输入:installutil -u  ..\Service\MyFirstWindowsService\MyFirstWindowsService\bin\Debug\MyFirstWindowsService.exe

1、服务效果如图

 

这就是我们新创建的服务,点击启动

2、在查看安装路径下的记录文件。

 

 这样一个服务就运行完成了。

 

 

注意,运行vs时一定要用管理员的身份运行
