Nlog从下载到使用例子

第一、首先下载nlog.dll 下载地址：http://pan.baidu.com/s/1i3DQsV7

第二、添加nlog.ll的引用

第三、代码

private static Logger log = LogManager.GetCurrentClassLogger();



        protected void Page_Load(object sender, EventArgs e)

        {



            //记录错误日志

            log.Error("发生了一个异常");

            //记录严重错误

            log.Fatal("发生了一个致命错误");

            //记录一般信息

            log.Info("info");

            //记录调试信息

            log.Debug("debug");

            //记录警告信息

            log.Warn("warn");



            try

            {

                throw new Exception("未将。。。");

            }

            catch (Exception ex)

            {

                log.Error("发生异常{0}", ex);

            }

        }

第四、config配置

<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      throwExceptions="true" internalLogFile="e:\nlog1.txt" internalLogLevel="DEBUG">



  <!-- 

  See http://nlog-project.org/wiki/Configuration_file 

  for information on customizing logging rules and outputs.

   -->

  <targets>

    <!-- add your targets here -->

    <target name="file" xsi:type="File"  fileName="E:\bzylog/${shortdate}.txt"

            layout="${longdate} ${level}:${message} ${stacktrace}" />

    <target name="fi" xsi:type="File" fileName="App_Data/Log ${shortdate}.txt"

           layout="${longdate} ${level}:${message} ${stacktrace}" />

    <!--<target type="Database" name="database" connectionstring="Data Source=.;Initial Catalog=ReportServerTempDB;Integrated Security=True">

      <commandText>

        insert into DevLog ([AppName],[ModuleName],[ProcName],[LogLevel],[LogTitle],[LogMessage],[LogDate],[StackTrace]) values (@appName, @moduleName, @procName, @logLevel, @logTitle, @logMessage,@logDate,@stackTrace);

      </commandText>

      <parameter name="@appName" layout="${event-context:item=appName}"/>

      <parameter name="@moduleName" layout="${event-context:item=moduleName}"/>

      <parameter name="@procName" layout="${event-context:item=procName}"/>

      <parameter name="@logDate" layout="${longdate}"/>

      <parameter name="@stackTrace" layout="${stacktrace}"/>

    </target>-->

    <!--

    <target xsi:type="File" name="f" fileName="${basedir}/logs/${shortdate}.log"

            layout="${longdate} ${uppercase:${level}} ${message}" />

    -->

  </targets>



  <rules>

    <!-- add your logging rules here -->



    <logger name="*"   writeTo="file"/>

    <!--<logger name="*"  levels="Debug,Error" writeTo="fi"/>-->

    <!--<logger name="Log" minlevel="Info" appendTo="database"/>-->

    <!--

    <logger name="*" minlevel="Trace" writeTo="f" />

    -->

  </rules>

</nlog>
