Question

我在asp.net中使用Microsoft Enterprise Library 3.1进行异常处理，错误存储在系统的事件查看器中。

我需要使用Enterprise Library将这些错误存储在日志文件中，而不是事件查看器。

亲爱的2:30，您将以下代码粘贴在app.config或web.config文件

的配置部分中

  <configSections>
    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" />
    <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" />
  </configSections>
  <loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="Tracing" logWarningsWhenNoCategoriesMatch="true">
    <listeners>
      <add fileName="AppLog.log" rollSizeKB="1024" timeStampPattern="yyyy-MM-dd" rollFileExistsBehavior="Increment" rollInterval="None" formatter="Text Formatter" header="" footer="" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.RollingFlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" traceOutputOptions="LogicalOperationStack" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" name="AppLog" />
      <add fileName="Exception.log" rollSizeKB="1024" timeStampPattern="MM-dd-yyyy" rollFileExistsBehavior="Increment" rollInterval="None" formatter="Text Formatter" header="" footer="" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.RollingFlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" traceOutputOptions="Callstack" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" name="Exception" />
      <add fileName="trace.log" rollSizeKB="1024" timeStampPattern="yyyy-MM-dd" rollFileExistsBehavior="Increment" rollInterval="Month" formatter="Text Formatter" header="----------------------------------------" footer="----------------------------------------" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.RollingFlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" traceOutputOptions="None" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" name="Trace" />
    </listeners>
    <formatters>
      <add template="{timestamp} : {message}" type="Microsoft.Practices.EnterpriseLibrary.Logging.Formatters.TextFormatter, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=null" name="Text Formatter" />
    </formatters>
    <categorySources>
      <add switchValue="All" name="AppLog">
        <listeners>
          <add name="AppLog" />
        </listeners>
      </add>
      <add switchValue="Verbose" name="ExceptionHandling">
        <listeners>
          <add name="Exception" />
        </listeners>
      </add>
      <add switchValue="Information" name="Tracing">
        <listeners>
          <add name="Trace" />
        </listeners>
      </add>
    </categorySources>
    <specialSources>
      <allEvents switchValue="All" name="All Events" />
      <notProcessed switchValue="All" name="Unprocessed Category" />
      <errors switchValue="Off" name="Logging Errors &amp; Warnings" />
    </specialSources>
  </loggingConfiguration>

可以使用以下语句将应用程序日志记录到applog.log文件中

Logger.Write("Application Started", "AppLog");

可以使用以下语句将应用程序异常记录到Exception.log文件中

Logger.Write("Error: Invalid information you passed", "ExceptionHandling");

注意：您可以在Microsoft.Practices.EnterpriseLibrary.Logging中找到Logger类;

AppLog.log和Exception.log文件将自动在bin文件夹中创建。

在Entlib中，类别连接到侦听器，然后侦听器确定日志信息的写入位置。要使用平面文件侦听器登录文件。

<listeners>
  <add fileName="..\..\logfiles\BusinessActivity.log" rollSizeKB="10000" timeStampPattern="yyyy-MM-dd" rollFileExistsBehavior="Increment" rollInterval="None" formatter="Text Formatter" header="----------------------------------------" footer="----------------------------------------" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.RollingFlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" traceOutputOptions="None" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.RollingFlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" name="Rolling Flat File BusinessActivity Listener" />
</listeners>
<formatters>

</formatters>
<categorySources>
  <add switchValue="All" name="BusinessActivityLog">
    <listeners>
      <add name="Rolling Flat File BusinessActivity Listener" />
    </listeners>

您需要阅读有关平面文件跟踪侦听器/滚动平面文件跟踪侦听器和Trace Listeners的一般信息。
