Question

我的AdoNetAppender出现问题 - 它只是没有记录。我已经阅读了log4net手册和各种其他链接，但看不出我做错了什么。以下是我的配置文件以及我如何调用它，所以任何帮助都将非常感谢！

您正在尝试使用存储过程将Log4Net日志存储在数据库中。从你拥有的，我只能想到可能导致问题的这两件事。

1）conversionPattern的值不正确。见下文：

   <parameter>
    <parameterName value="@HTTPMethod" />
    <dbType value="String" />
    <size value="10" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%message" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@URI" />
    <dbType value="String" />
    <size value="512" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{URI}" /> <- here use property instead of "UserID"
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@RequestData" />
    <dbType value="String" />
    <size value="1024" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{RequestData}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@UserID" />
    <dbType value="int" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{UserID}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@UserToDealerID" />
    <dbType value="int" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{UserToDealerID}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@AdminID" />
    <dbType value="String" />
    <size value="256" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{AdminID}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@SessionID" />
    <dbType value="String" />
    <size value="256" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{SessionID}" />
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@BrowserInfo" />
    <dbType value="String" />
    <size value="1024" />
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%property{BrowserInfo}" />
    </layout>
  </parameter>

2）如果您更改为上面的代码，它仍然无效。考虑log4Net参数是否匹配存储过程中的参数。您可以尝试使用虚假数据并执行存储过程在Logger.Debug（）之前的任何地方。如果它有效，问题是，

 Logger.Debug(auditModel.Method);

希望这有帮助。
