我的配置有问题EmailTraceListener。我收到ActivationException此消息的内部异常：

无法构造类型 TraceListener。您必须配置容器以提供此值。

这是我的 app.config 日志记录配置代码：

<configuration>
  <configSections>

  </configSections>
  <loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="" logWarningsWhenNoCategoriesMatch="true">
    <listeners>
      <add 
        name="Email Trace Listener"

        formatter="Text Formatter"/>
    </listeners>
    <formatters>

{dictionary([P]: {key}{tab}= {value}
)}"
        name="Text Formatter" />
    </formatters>
    <specialSources>
      <allEvents switchValue="All" name="All Events">
        <listeners>
          <add name="FlatFile TraceListener"/>
        </listeners>
      </allEvents>
      <notProcessed switchValue="All" name="Unprocessed Category"/>
      <errors switchValue="All" name="Logging Errors &amp; Warnings"/>
    </specialSources>
  </loggingConfiguration>
</configuration>

如果我用平面文件侦听器配置替换电子邮件侦听器配置 - 一切正常。电子邮件侦听器配置的错误在哪里？

问题是您的所有事件类别仍然连接到不再存在的 FlatFile TraceListener。您的文件还有其他几个可能应该解决的错误。我建议使用配置控制台而不是手动编写配置代码，或者至少在完成验证后在配置控制台中打开您的配置。
