使用Topshelf创建Windows服务

Topshelf是一个开源的跨平台的宿主服务框架，支持Windows和Mono，只需要几行代码就可以构建一个很方便使用的服务宿主。

1. 新建一个控制台项目，引用Topshelf和Log4net：

Install-Package Topshelf
Install-Package Topshelf.Log4Net

2. 修改相关文件。
Program.cs：

using System;
using System.IO;
using System.Timers;
using log4net;
using log4net.Config;
using Topshelf;

namespace TopshelfDemo
{
    public class TownCrier
    {
        readonly Timer _timer;
        readonly ILog _log = LogManager.GetLogger(typeof(TownCrier));

        public TownCrier()
        {
            _timer = new Timer(5000) { AutoReset = true };
            _timer.Elapsed += (sender, eventArgs) => 
            {
                _log.Info(DateTime.Now);
            };
        }
        public void Start() { _timer.Start(); }
        public void Stop() { _timer.Stop(); }
    }

    class Program
    {
        public static void Main()
        {
            var logCfg = new FileInfo(AppDomain.CurrentDomain.BaseDirectory + "log4net.xml");
            XmlConfigurator.ConfigureAndWatch(logCfg);

            HostFactory.Run(x =>
            {
                x.Service<TownCrier>(s =>
                {
                    s.ConstructUsing(name => new TownCrier());
                    s.WhenStarted(tc => tc.Start());
                    s.WhenStopped(tc => tc.Stop());
                });
                x.RunAsLocalSystem();

                x.SetDescription("Sample Topshelf Host");
                x.SetDisplayName("Stuff");
                x.SetServiceName("Stuff");
            });
        }
    }
}

log4net.xml：

<?xml version="1.0" encoding="utf-8" ?>
<log4net>
  <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
    <!--日志路径-->
    <param name= "File" value= "Logs\"/>
    <!--是否是向文件中追加日志-->
    <param name= "AppendToFile" value= "true"/>
    <!--log保留天数-->
    <param name= "MaxSizeRollBackups" value= "10"/>
    <!--日志文件名是否是固定不变的-->
    <param name= "StaticLogFileName" value= "false"/>
    <!--日志文件名格式为:2008-08-31.log-->
    <param name= "DatePattern" value= "yyyy-MM-dd&quot;.log&quot;"/>
    <!--日志根据日期滚动-->
    <param name= "RollingStyle" value= "Date"/>
    <layout type="log4net.Layout.PatternLayout">
      <param name="ConversionPattern" value="[%d] [%p] [%c] - %m%n" />
    </layout>
  </appender>

  <!-- 控制台前台显示日志 -->
  <appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
    <mapping>
      <level value="ERROR" />
      <foreColor value="Red, HighIntensity" />
    </mapping>
    <mapping>
      <level value="Info" />
      <foreColor value="Green" />
    </mapping>
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%n%date{HH:mm:ss,fff} [%-5level] %m" />
    </layout>

    <filter type="log4net.Filter.LevelRangeFilter">
      <param name="LevelMin" value="Info" />
      <param name="LevelMax" value="Fatal" />
    </filter>
  </appender>

  <root>
    <!--(高) OFF > FATAL > ERROR > WARN > INFO > DEBUG > ALL (低) -->
    <level value="all" />
    <appender-ref ref="ColoredConsoleAppender"/>
    <appender-ref ref="RollingLogFileAppender"/>
  </root>
</log4net>

3. 执行，在控制台和日志文件中每5秒钟显示一条时间信息：

4. 服务相关操作：
安装：TopshelfDemo.exe install
启动：TopshelfDemo.exe start
卸载：TopshelfDemo.exe uninstall
