伙计们

我正在尝试将LogCallHandler用于拦截,如下所示:

<interception>
        <policy name="policyLogCallHandler">
          <matchingRule name="LogsMachingRule" type="NamespaceMatchingRule">
            <constructor>
              <param name="namespaceName" value="NetTcpContracts" />
            </constructor>
          </matchingRule>
          <callHandler type="Microsoft.Practices.EnterpriseLibrary.Logging.PolicyInjection.LogCallHandler, Microsoft.Practices.EnterpriseLibrary.PolicyInjection, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="callHandlerLog">
            <constructor>
              <param name="eventId" value="9002"/>
              <param name="logBeforeCall" value="true"/>
              <param name="logAfterCall" value="true"/>
              <param name="beforeMessage" value="--- begin"/>
              <param name="afterMessage" value="--- end"/>
              <param name="includeParameters" value="true"/>
              <param name="includeCallStack" value="true"/>
              <param name="includeCallTime" value="true"/>
              <param name="priority" value="1"/>
              <param name="order" value="1"/>
            </constructor>            
          </callHandler>
        </policy>        
      </interception>

此配置引发异常:"尚未为Logger静态类设置LogWriter.设置它调用Logger.SetLogWriter方法."

我使用运行时配置找到了解决此问题的方法:

IConfigurationSource configurationSource = ConfigurationSourceFactory.Create();
LogWriterFactory logWriterFactory = new LogWriterFactory(configurationSource);
Logger.SetLogWriter(logWriterFactory.Create());
LogEntry entry = new LogEntry();
entry.Message = "I am …
