asp.net - 如何在 SQL Server 的 log4net 配置中使用存储过程进行日志记录

Question

如何更新存储过程的 commandText 和参数部分，以便可以通过 log4net 将错误记录到 SQL Server 中？

我使用的是 SQL Server 2008，我的附加程序配置如下所示:

<appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
  <bufferSize value="100"/> 
  <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/> 
  <connectionString value="server=MYSERVER; uid=MYUSER; pwd=MYPASS; database=MYDB"/> 
  <commandText 
    value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)"

    />
  <parameter>
    <parameterName value="@log_date"/> 
    <dbType value="DateTime"/> 
    <layout type="log4net.Layout.RawTimeStampLayout"/>
  </parameter>
  <parameter>
    <parameterName value="@thread"/> 
    <dbType value="String"/> <size value="255"/> 
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%thread"/>
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@log_level"/> 
    <dbType value="String"/> 
    <size value="50"/> 
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%level"/>
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@logger"/> 
    <dbType value="String"/> 
    <size value="255"/> 
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%logger"/>
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@message"/> 
    <dbType value="String"/> 
    <size value="4000"/> 
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%message"/>
    </layout>
  </parameter>
  <parameter>
    <parameterName value="@exception"/> 
    <dbType value="String"/> 
    <size value="2000"/> 
    <layout type="log4net.Layout.ExceptionLayout"/>
  </parameter>
</appender>

尝试一下:

 <commandText value="StorProcName" />
 <commandType value="StoredProcedure" />

 <parameter>
    <parameterName value="@log_date" />
    <dbType value="DateTime" />
    <layout type="log4net.Layout.RawTimeStampLayout" />
 </parameter>
 ... all parameters ...

log4net online config examples page :

The CommandText is either a prepared statement or a stored procedure. Each parameter to the prepared statement or stored procedure is specified with its name, database type and a layout that renders the value for the parameter.
