Question

我试图使用log4net在两个不同的表中创建日志。第一个adonetappender将登录一个名为＆＃39; log＆＃39;并且应该是标准的id，日期，线程，级别等等。第二个adonetappender需要登录到一个表，其中包含三个名为＆＃39; usageLog＆＃39;并且只需要记录日期/时间和两个额外的字符串值。我不能为我的生活弄清楚。我需要做什么？到目前为止，下面是我的配置。我不确定它是否正确，我不知道如何在程序中使用它。

<log4net>
<logger additivity="false" name="Log">
  <level value="INFO"/>
  <appender-ref ref="LogAppender" />
</logger>
<logger additivity="false" name="UsageLog">
  <level value="INFO"/>
  <appender-ref ref="UsageLogAppender" />
</logger>

<appender name="LogAppender" type="log4net.Appender.AdoNetAppender">
  <bufferSize value="1" />
  <!-- Causes errors to be written immediately - default is 100 -->
  <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
  <connectionString value="data source=dummy;initial catalog=dummy;integrated security=false;persist security info=True;User ID=dummy;Password=dummy" />

在我看来，您希望将相同的消息记录到具有不同列的两个不同表中。如果这是真的，您似乎错过了根记录器：

<root>
  <level value="INFO" />
  <appender-ref ref="LogAppender" />
  <appender-ref ref="UsageLogAppender" />
</root>

但是，如果您在代码中声明这样的记录器，并且只希望那些特定的记录器记录到这些不同的故事表：

private readonly static ILog log = LogManager.GetLogger("Log");
private readonly static ILog log = LogManager.GetLogger("UsageLog");

通过在代码中以这种方式声明您的记录器，您的上述配置仍应有效。如果您没有以这种方式声明日志，则不会记录任何内容。打开log4net日志记录总是有帮助的：
