.net MVC Nlog使用

1、NLog dll 引用

2、添加 NLog.config 配置文件

<?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">

  <!-- 
  See http://nlog-project.org/wiki/Configuration_file 
  for information on customizing logging rules and outputs.
   -->

  <targets>
    <!-- add your targets here -->
    <!-- 记录一般INFO文本日志(启用异步) -->
    <target name="file" xsi:type="AsyncWrapper" queueLimit="5000" overflowAction="Discard">
      <!--<target xsi:type="File" fileName="${basedir}/logs/${shortdate}/${level}.log"  layout="${longdate} ${uppercase:${level}} ${message}"  maxArchiveFiles="100" />-->
      <target xsi:type="File" fileName="${basedir}/logs/${shortdate}.log"  layout="${longdate} ${uppercase:${level}} ${message}"  maxArchiveFiles="100" />

    </target>

    <!-- 发生错误异常记录数据库日志 -->
    <target name="database" xsi:type="Database"  useTransactions="true" connectionString="Data Source=xxxxxxxx;Initial Catalog=Log;Persist Security Info=True;User ID=sa;Password=123456"  commandText="insert into NLogException_HomeinnsInterface([CreateOn],[Origin],[LogLevel], [Message], [Exception],[StackTrace]) values (getdate(), @origin, @logLevel, @message,@exception, @stackTrace);">
      <!--日志来源-->
      <parameter name="@origin" layout="${callsite}"/>
      <!--日志等级-->
      <parameter name="@logLevel" layout="${level}"/>
      <!--日志消息-->
      <parameter name="@message" layout="${message}"/>
      <!--异常信息-->
      <parameter name="@exception" layout="${exception}" />
      <!--堆栈信息-->
      <parameter name="@stackTrace" layout="${stacktrace}"/>
    </target>


  </targets>
  <rules>
    <!-- add your logging rules here -->
    <logger name="*" minlevel="Trace" writeTo="console" />
    <logger name="*" minlevel="Info" writeTo="file" />
    <logger name="*" minlevel="Error" writeTo="database"/>
    <logger name="*" minlevel="Fatal" writeTo="email" />
    <logger name="*" minlevel="Debug" writeTo="f" />
  </rules>
</nlog>

3、程序使用

 private Logger Logger = LogManager.GetCurrentClassLogger();
        public ActionResult Index()
        {

            Logger.Info("testlog记录");
            Logger.Error("222testlog记录");
            return View();
        }
