零基础WPF使用NLog记录日志

使用步骤：

1、NuGet安装NLog.conf包即可，这个包会同时安装其他的依赖包；

2、修改NLog.conf的配置，配置参数参考：NLog详解-CSDN博客

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
      autoReload="true"
      throwExceptions="false"
      internalLogLevel="Off" internalLogFile="c:\temp\nlog-internal.log">

  <variable name="myvar" value="myvalue"/>
  <targets>
  <!-- 写入文件的配置 -->
	<target name="info_file" xsi:type="File"
				fileName="${basedir}/logs/info_file.txt"
				archiveFileName="${basedir}/logs/info_file.{###}.txt"
				archiveEvery="Day"
				archiveNumbering="DateAndSequence"
				archiveAboveSize="10000000"
				maxArchiveFiles="90"
				keepFileOpen="true"
				layout="${longdate} ${uppercase:${level}} ${message} ${exception:stacktrace}" />
				
	

  </targets>

  <rules>
      <!-- 记录的级别 -->
    <logger name="*" minlevel="Info" writeTo="info_file" />
   
  </rules>
</nlog>

3、新建一个日志的类，后续方便统一使用打印

using System;
using System.Collections.Generic;
using NLog;

namespace XXX项目的命令空间XXX
{
    internal class LoggerHelper
    {
        public static Logger logger = LogManager.GetCurrentClassLogger(); //初始化日志类

       /// <summary>
       /// 
       /// </summary>
       /// <param name="errorFile">错误源文件</param>
       /// <param name="errorMsg">错误消息</param>
       /// <param name="errorFunc">错误函数</param>
        public static void Logger_Debug(string errorFile,string errorMsg ,string errorFunc="")
        {
            string errorStr="调试源文件：《"+errorFile+"》，调试源函数：["+errorFunc+ "]，调试信息：" + errorMsg;
            logger.Debug(errorStr);
        }

        /// <summary>
        /// 
        /// </summary>
        /// <param name="errorFile">错误源文件</param>
        /// <param name="errorMsg">错误消息</param>
        /// <param name="errorFunc">错误函数</param>
        public static void Logger_Info(string errorFile, string errorMsg, string errorFunc = "")
        {
            string errorStr = "源文件：《" + errorFile + "》，源函数：[" + errorFunc + "]，信息：" + errorMsg;
            logger.Info(errorStr);
        }

        /// <summary>
        /// 
        /// </summary>
        /// <param name="errorFile">错误源文件</param>
        /// <param name="errorMsg">错误消息</param>
        /// <param name="errorFunc">错误函数</param>
        public static void Logger_Warn(string errorFile, string errorMsg, string errorFunc = "")
        {
            string errorStr = "警告源文件：《" + errorFile + "》，警告源函数：[" + errorFunc + "]，警告信息：" + errorMsg;
            logger.Warn(errorStr);
        }

        /// <summary>
        /// 
        /// </summary>
        /// <param name="errorFile">错误源文件</param>
        /// <param name="errorMsg">错误消息</param>
        /// <param name="errorFunc">错误函数</param>
        public static void Logger_Error(string errorFile, string errorMsg, string errorFunc = "")
        {
            string errorStr = "错误源文件：《" + errorFile + "》，错误源函数：[" + errorFunc + "]，错误信息：" + errorMsg;
            logger.Error(errorStr);
        }
    }
}
