如何查看log4net日志路径？

Question

我的配置文件是:

<log4net  xsi:noNamespaceSchemaLocation="http://csharptest.net/downloads/schema/log4net.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <appender name="InfoFileAppender" type="log4net.Appender.RollingFileAppender">
            <file value="D:/" />
            <appendToFile value="true" />
            <param name="DatePattern" value="yyyyMMdd&quot;.txt&quot;" />
            <rollingStyle value="Date" />
            <maxSizeRollBackups value="100" />
            <datePattern value="YYYY-MM-DD'.log'"/>
            <maximumFileSize value="1024KB" />
            <staticLogFileName value="false" />
            <encoding value="utf-8"/>           
            <filter type="log4net.Filter.LevelRangeFilter">
                <param name="LevelMin" value="INFO" />
                <param name="LevelMax" value="INFO" />
            </filter>
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%date %-5level %logger  - %message%newline" />
            </layout>
        </appender>
        <appender name="ErrorFileAppender" type="log4net.Appender.RollingFileAppender">
            <file value="D:/" />
            <appendToFile value="true" />
            <rollingStyle value="Size" />
            <maxSizeRollBackups value="100" />
            <maximumFileSize value="10240KB" />
            <datePattern value="YYYY-MM-DD'.log'"/>
            <staticLogFileName value="true" />
            <encoding value="utf-8"/>
            <filter type="log4net.Filter.LevelRangeFilter">
                <param name="LevelMin" value="WARN" />
                <param name="LevelMax" value="FATAL" />
            </filter>
            <layout type="log4net.Layout.PatternLayout">
                <conversionPattern value="%date %-5level %logger - %message%newline" />
            </layout>
        </appender>
        <root>
            <level value="INFO" />
            <appender-ref ref="InfoFileAppender" />
            <appender-ref ref="ErrorFileAppender" />
        </root>
    </log4net>

在app.config中.

但它在磁盘D中没有日志文件:!!!!

刚验证了你的配置 - 工作正常.您可能没有正确初始化log4net.您应该添加到AssemblyInfo.cs文件中:

[assembly: XmlConfigurator(Watch = true)]

或者您可以使用XmlConfigurator.ConfigureAndWatch方法或简单地使用

XmlConfigurator.Configure();

与NLog不同,log4net无法初始化.

注意:您应该将日期模式更改为yyyy-MM-dd'.log'- 年和日应为小写字母.你也可以用单个appender写几个级别.无需创建两个写入同一文件的appender.
