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);}}
}
