现在我收到错误“无法在应用程序的.config
文件中找到配置部分'log4net'。这是log4net.config
文件中的代码:
<?xml version="1.0" encoding="utf-8" ?>
<log4net>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
</configSections>
<root>
<level Value="Info"/>
<level Value="Error"/>
<appender-ref ref="ColoredFileAppender" />
</root>
<appender name="ColoredFileAppender" type="log4net.Appender.RollingFileAppender" >
<file type="log4net.Util.PatternString"/>
<file value="C:\CL2.html" />
<encoding value="utf-8" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<appendToFile value="false" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%CC" />
<converter>
<name value="CC" />
<type value="Cluster2.ColoredMessageConverter" />
</converter>
<mapping>
<level value="Info" />
<foreColor value="Green" />
</mapping>
<mapping>
<level value="ERROR" />
<backColor value="Red, HighIntensity" />
</mapping>
</layout>
</appender>
</configuration>
</log4net>
我已将此声明包含在程序集中:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
我已在程序中包含此声明:
protected void Application_start(Object Sender, EventArgs e)
{
log4net.Config.XmlConfigurator.Configure();
}
我不知道是什么问题。请帮忙。

您必须使用自定义模式布局来实现此目的,然后将其连接到log4net.config文件中。 您的代码如下:
public class ColoredMessageConverter : PatternLayoutConverter
{
protected override void Convert(TextWriter writer, LoggingEvent loggingEvent)
{
string color = "";
switch (loggingEvent.Level.Name)
{
case "DEBUG":
color = "green";
break;
case "WARN":
case "INFO":
color = "white";
break;
case "ERROR":
color = "pink";
break;
case "FATAL":
color = "red";
break;
}
string logToRender = string.Format(" <p style='color:{0}'>{1}</p>", color, loggingEvent.RenderedMessage);
//Add logToRender to file
writer.Write(logToRender);
}
}
在你的log4net.config中,连接这个转换器,如下所示。用正确的名称替换“你的命名空间”。
<log4net>
<root>
<level value="DEBUG" />
<appender-ref ref="ColoredFileAppender" />
</root>
<appender name="ColoredFileAppender" type="log4net.Appender.RollingFileAppender" >
<file type="log4net.Util.PatternString" value="c:\test.html" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%CC" />
<converter>
<name value="CC" />
<type value="<<Your namespace>>.ColoredMessageConverter" />
</converter>
</layout>
</appender>

建议添加以上内容,这是添加日期/级别/方法以及该信息的代码
公共类LoggerColoredMessageConverter:PatternLayoutConverter {
protected override void Convert(TextWriter writer, LoggingEvent loggingEvent)
{
string color = "";
switch (loggingEvent.Level.Name)
{
case "DEBUG":
color = "#383d41";
break;
case "WARN":
color = "#856404";
break;
case "INFO":
color = "#0c5460;";
break;
case "ERROR":
case "FATAL":
color = "#721c24";
break;
}
string logToRender = string.Format(" <p style='color:{0}'>{1} {2} {3}" +
" - {4}</p>", color, loggingEvent.TimeStamp, loggingEvent.Level.Name,
loggingEvent.LoggerName,
loggingEvent.RenderedMessage);
//Add logToRender to file
writer.Write(logToRender);
}
}
以这种方式记录它:
