原文：https://www.cnblogs.com/donaldtdz/p/8213440.html

一、说明

NLog介绍和使用说明官网：http://nlog-project.org/
NLog和Log4net对比：https://www.cnblogs.com/qinjin/p/5134982.html

二、NLog集成步骤

下载模板项目，下载地址：https://aspnetboilerplate.com/Templates 选择.Net Core项目
新建一个.NET Standard类库项目Abp.Castle.NLog
添加NuGet包Castle.Core, Castle.LoggingFacility, NLog

参考abp log4net（ABP源码）添加class NLogLogger继承MarshalByRefObject并实现接口Castle.Core.Logging.ILogger

  1 using System;
  2 using System.Globalization;
  3 using ILogger = Castle.Core.Logging.ILogger;
  4 using NLogCore = NLog;
  5 
  6 namespace Abp.Castle.Logging.NLog
  7 {
  8     [Serializable]
  9     public class NLogLogger :
 10         MarshalByRefObject,
 11         ILogger
 12     {
 13         protected internal NLogCore.ILogger Logger { get; set; }
 14         //protected internal NLogLoggerFactory Factory { get; set; }
 15 
 16         public NLogLogger(NLogCore.ILogger logger)
 17         {
 18             Logger = logger;
 19         }
 20 
 21         internal NLogLogger()

212             Logger.Warn(exception, formatProvider, format, args);
213         }
214     }
215 }

添加工厂类NLogLoggerFactory并实现抽象类Castle.Core.Logging.AbstractLoggerFactory

 1 using Castle.Core.Logging;
 2 using System;
 3 using System.IO;
 4 using NLogCore = NLog;
 5 
 6 namespace Abp.Castle.Logging.NLog
 7 {
 8 
 9     public class NLogLoggerFactory : AbstractLoggerFactory
10     {
11         internal const string DefaultConfigFileName = "nlog.config";
12         //private readonly ILoggerRepository _loggerRepository;
13 
14         public NLogLoggerFactory()
15        : this(DefaultConfigFileName)
16         {
17 
18         }
19 
20         public NLogLoggerFactory(string configFileName)
21         {
22             if (!File.Exists(configFileName))
23             {
24                 throw new FileNotFoundException(configFileName);
25             }
26             NLogCore.LogManager.Configuration = new NLogCore.Config.XmlLoggingConfiguration(configFileName);
27         }
28 
29         public override ILogger Create(string name)
30         {
31             if (name == null)
32             {
33                 throw new ArgumentNullException(nameof(name));
34             }
35             return new NLogLogger(NLogCore.LogManager.GetLogger(name));
36         }
37 
38         public override ILogger Create(string name, LoggerLevel level)
39         {
40             throw new NotSupportedException("Logger levels cannot be set at runtime. Please review your configuration file.");
41         }
42     }
43 }

添加LoggingFacility的扩展方法UseAbpNLog

 1 using Castle.Facilities.Logging;
 2 
 3 namespace Abp.Castle.Logging.NLog
 4 {
 5     public static class LoggingFacilityExtensions
 6     {
 7         public static LoggingFacility UseAbpNLog(this LoggingFacility loggingFacility)
 8         {
 9             return loggingFacility.LogUsing<NLogLoggerFactory>();
10         }
11     }
12 }

移除Abp.Castle.Log4Net包，添加Abp.Castle.NLog到Host项目

添加配置文件nlog.config

 1 <?xml version="1.0" encoding="utf-8" ?>
 2 <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
 3       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 4       autoReload="true"
 5       internalLogLevel="Warn"
 6       internalLogFile="App_DataLogs
logs.txt">
 7 
 8   <variable name="logDirectory" value="${basedir}log"/>
 9 
10   <!--define various log targets-->
11   <targets>
12 
13     <!--write logs to file-->
14     <target xsi:type="File" name="allfile" fileName="${logDirectory}
log-all-${shortdate}.log"
15                  layout="${longdate}|${logger}|${uppercase:${level}}|${message} ${exception}" />
16 
17     <target xsi:type="File" name="ownFile-web" fileName="nlog-my-${shortdate}.log"
18                  layout="${longdate}|${logger}|${uppercase:${level}}|${message} ${exception}" />
19 
20     <target xsi:type="Null" name="blackhole" />
21 
22   </targets>
23 
24   <rules>
25     <!--All logs, including from Microsoft-->
26     <logger name="*" minlevel="Trace" writeTo="allfile" />
27 
28     <!--Skip Microsoft logs and so log only own logs-->
29     <logger name="Microsoft.*" minlevel="Trace" writeTo="blackhole" final="true" />
30     <logger name="*" minlevel="Trace" writeTo="ownFile-web" />
31   </rules>
32 </nlog>

修改Startup, 将原来的日志组件log4net替换为nlog

注释using Abp.Castle.Logging.Log4Net; 添加using Abp.Castle.Logging.NLog;

1 //using Abp.Castle.Logging.Log4Net;
2 using Abp.Castle.Logging.NLog;

修改ConfigureServices方法

 1 　// Configure Abp and Dependency Injection
 2  return services.AddAbp<AbpBasicWebHostModule>(
 3      // Configure Log4Net logging
 4      //options => options.IocManager.IocContainer.AddFacility<LoggingFacility>(
 5      //    f => f.UseAbpLog4Net().WithConfig("log4net.config")
 6      //)
 7 
 8      // Configure Nlog Logging
 9       options => options.IocManager.IocContainer.AddFacility<LoggingFacility>(
10       f => f.UseAbpNLog().WithConfig("nlog.config")
11       )
12   );

测试

 1 public IActionResult Index()
 2 {
 3       //nlog test
 4        Logger.Info("信息日志");
 5        Logger.Debug("调试日志");
 6        Logger.Error("错误日志");
 7        Logger.Fatal("异常日志");
 8        Logger.Warn("警告日志");
 9        return Redirect("/swagger");
10 }
