可调试Windows服务框架

参考：

Build A Windows Service Framework

新建ServiceFramework类库，项目中需引用：

using System.Configuration.Install;
using System.ServiceProcess;

三个类BasicServiceStarter、BasicServiceInstaller、BasicService的代码：

class BasicService<T> : ServiceBase where T : IDisposable, new()
    {
        private IDisposable _service;

        protected override void OnStart(string[] args)
        {
            try
            {
                _service = new T();
            }
            catch
            {
                ExitCode = ;
                throw;
            }
        }

        protected override void OnStop()
        {
            _service.Dispose();
        }
    }

static class BasicServiceInstaller
    {
        public static void Install(string serviceName)
        {
            CreateInstaller(serviceName).Install(new Hashtable());
        }

        public static void Uninstall(string serviceName)
        {
            CreateInstaller(serviceName).Uninstall(null);
        }

        private static Installer CreateInstaller(string serviceName)
        {
            var installer = new TransactedInstaller();
            installer.Installers.Add(new ServiceInstaller
            {
                ServiceName = serviceName,
                DisplayName = serviceName,
                StartType = ServiceStartMode.Manual
            });
            installer.Installers.Add(new ServiceProcessInstaller
            {
                Account = ServiceAccount.LocalSystem
            });
            var installContext = new InstallContext(
                serviceName + ".install.log", null);
            installContext.Parameters["assemblypath"] =
                Assembly.GetEntryAssembly().Location;
            installer.Context = installContext;
            return installer;
        }
    }

public static class BasicServiceStarter
    {
        public static void Run<T>(string serviceName) where T : IDisposable, new()
        {
            AppDomain.CurrentDomain.UnhandledException += (s, e) =>
            {
                if (EventLog.SourceExists(serviceName))
                {
                    EventLog.WriteEntry(serviceName,
                        "Fatal Exception : " + Environment.NewLine +
                        e.ExceptionObject, EventLogEntryType.Error);
                }
            };

            if (Environment.UserInteractive)
            {
                var cmd =
                    (Environment.GetCommandLineArgs().Skip().FirstOrDefault() ?? "")
                    .ToLower();
                switch (cmd)
                {
                    case "i":
                    case "install":
                        Console.WriteLine("Installing {0}", serviceName);
                        BasicServiceInstaller.Install(serviceName);
                        break;
                    case "u":
                    case "uninstall":
                        Console.WriteLine("Uninstalling {0}", serviceName);
                        BasicServiceInstaller.Uninstall(serviceName);
                        break;
                    default:
                        using (var service = new T())
                        {
                            Console.WriteLine(
                                "Running {0}, press any key to stop", serviceName);
                            Console.ReadKey();
                        }
                        break;
                }
            }
            else
            {
                ServiceBase.Run(new BasicService<T> { ServiceName = serviceName });
            }
        }
    }

新建控制台应用程序MyWindowsService，引用ServiceFramework

新建服务应用类，在默认构造函数中执行服务的代码：

class MyService:IDisposable
    {
        public MyService()
        {
            Console.WriteLine("服务启动");
            //do something
        }

        public void Dispose()
        {
            Console.WriteLine("服务停止");
        }
    }

在Main中调用服务：

class Program
    {
        private const string Name = "我的服务";
        static void Main(string[] args)
        {
            BasicServiceStarter.Run<MyService>(Name);
        }
    }

服务的调试及安装与上一篇

使用Topshelf部署Windows服务

相同，这里可以在快捷方式中直接加“i"和”u"即可。

依然可以使用log4net来记录日志：

引用log4net：

install-package log4net

加入log4net.config配置文件，主要此文件一定要始终复制到输出目录

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
  </configSections>
  <log4net>
    <!--定义输出到文件中-->
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <!--定义文件存放位置-->
      <file value="log\\"/>
      <!--是否追加到文件,默认为true，通常无需设置-->
      <appendToFile value="true"/>
      <!--多线程时采用最小锁定-->
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
      <!--变换的形式为日志大小-->
      <!--这种情况下MaxSizeRollBackups和maximumFileSize的节点设置才有意义-->
      <!--<rollingStyle value="Size"/>-->
      <!--每天记录的日志文件个数，与maximumFileSize配合使用-->
      <!--<MaxSizeRollBackups value="/>-->
      <!--每个日志文件的最大大小-->
      <!--可用的单位:KB|MB|GB-->
      <!--不要使用小数,否则会一直写入当前日志-->
      <!--<maximumFileSize value="2MB"/>-->

      <!--变换的形式为日期，这种情况下每天只有一个日志-->
      <!--此时MaxSizeRollBackups和maximumFileSize的节点设置没有意义-->
      <rollingStyle value="Date"/>

      <!--每分钟写一个文件-->
      <!--<datePattern value="yyyyMMdd-HHmm" />-->
      <!--日期的格式，每天换一个文件记录，如不设置则永远只记录一天的日志，需设置-->

      <datePattern value="yyyyMMdd\\HH'.txt'"/>
      <staticLogFileName value="false"/>
      <param name="/>
      <layout type="log4net.Layout.PatternLayout">

      </layout>
    </appender>

    <!--定义输出到MySql中-->

      <appender-ref ref="RollingLogFileAppender"/>

    </root>
  </log4net>
</configuration>

更新后的Main：

    class Program
    {
        private const string Name = "我的服务";
        static void Main(string[] args)
        {
            FileInfo fi = new FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.config");
            XmlConfigurator.ConfigureAndWatch(fi);
            BasicServiceStarter.Run<MyService>(Name);
        }
    }

这里用Path.Combine方法更好：

FileInfo fi = new FileInfo(Path.Combine(AppDomain.CurrentDomain.BaseDirectory , "log4net.config"));
            XmlConfigurator.ConfigureAndWatch(fi);

更新后的MyService：

class MyService:IDisposable
    {
        readonly Timer _timer;
        readonly ILog _log = LogManager.GetLogger(typeof(MyService));
        public MyService()
        {
            Console.WriteLine("服务启动");
            _log.Info("Service is Started");
            //do something
            _timer = ) { AutoReset = true };
            _timer.Elapsed += new ElapsedEventHandler(OnTick);
            _timer.Elapsed += (sender, eventArgs) => Console.WriteLine("It is {0} and all is well", DateTime.Now);
            _timer.Start();
        }
        protected virtual void OnTick(object sender, ElapsedEventArgs e)
        {
            _log.Debug("Tick:" + DateTime.Now.ToLongTimeString());
        }
        public void Dispose()
        {
            Console.WriteLine("服务停止");
            _log.Info("Service is Stopped");
        }
    }
