log4.net 配置-控制台輸出帶顏色的日志

一般對控制台輸入的日志我們使用的 Appender 為 ConsoleAppender ，日志為白色文字。

當我們想到 DEBUG,INFO,WARN,ERROR  每種日志設置一種顏色時我們需要將 Appender 改為 ColoredConsoleAppender 

然后增加相應的顏色配置

 <appender name="ConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
      <mapping>
        <level value="ERROR" />
        <foreColor value="Red, HighIntensity" />
      </mapping>
      <mapping>
        <level value="Warn" />
        <foreColor value="Yellow,HighIntensity" />
      </mapping>
      <mapping>
        <level value="Info" />
        <foreColor value="White" />
      </mapping>
      <mapping>
        <level value="Debug" />
        <foreColor value="Purple, HighIntensity" />
      </mapping>
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
      </layout>
    </appender>

顏色的值可以為

Yellow
Purple
