带Gmail的Log4Net SMTP Appender

Question

我正在使用此代码。虽然我启用了Log4Net调试，但它没有错误。我也没有收到电子邮件。有任何想法吗？

我替换了登录凭据，并使用占位符替换了/。

<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
      <authentication value="Basic" />
      <to value="to" />
      <from value="from" />
      <subject value="Log message" />
      <username value="myusername" />
      <password value="mypass" />
      <smtpHost value="smtp.gmail.com" />
      <port value="587"/>
      <bufferSize value="1" />
      <EnableSsl value="true"/>
      <lossy value="true" />
      <threshold value="FATAL"/>
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date{ABSOLUTE} [%logger]%newlineUsername: %property{username}%newline%level - %message%newline%exception" />
      </layout>
</appender>

Answer 1

我知道它已经晚了但是更换了

 <threshold value="FATAL"/>

同

<evaluator type="log4net.Core.LevelEvaluator">
        <threshold value="ERROR" />
      </evaluator>

Answer 2

我建议将以下内容放入appSettings节点。

<appSettings>
  <add key="log4net.Internal.Debug" value="true"/>
</appSettings>

然后它将输出诊断信息，例如
