c# - 为什么 log4net 不写入文件？

Question

我已经添加了 log4net 的所有部分，但是它没有写入文件。
我正在处理 VS2012 LoadTest 项目。

在运行 LoadTest 项目时，System.Console.WriteLine 或 Debug.WriteLine() 都不起作用。

我添加了装配信息行:

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "web.config", Watch = true)]   //For log4net 1.2.10.0

我已经:
- 添加了 webconfig 部分
- 初始化并配置了一个 XML 初始化器
- 使用正确的日志初始化新的 log4net

我的应用程序配置:

  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  </configSections>

  <log4net debug="true">
    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
      <file value="Settings_CacheExplosion.txt" />
      <appendToFile value="true" />
      <rollingStyle value="Size" />
      <maxSizeRollBackups value="10" />
      <maximumFileSize value="10MB" />
      <staticLogFileName value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%-5p %d %5rms %-22.22c{1} %-18.18M - %m%n" />
      </layout>
    </appender>

    <root>
      <level value="DEBUG" />
      <appender-ref ref="RollingLogFileAppender" />
    </root>
  </log4net>

</configuration>

如果您希望 log4net 从 app.config 中读取，您必须将其添加到您的 AssemblyInfo.cs 文件中:

[assembly: log4net.Config.XmlConfigurator(Watch = true)]
