Send an Email When an Error Occurs
提问by swade1987
Currently my application is using log4net to log errors, the web.config for this is as followed:
目前我的应用程序正在使用 log4net 来记录错误，为此的 web.config 如下：
<log4net>
<appender name="FileAppender" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="../../logs/gateway_%date{yyyyMMdd}.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] – %message%newline" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="RollingLogFileAppenderOutput" />
</root>
</log4net>
However, the client now wants each error to be emailled to them.
但是，客户现在希望通过电子邮件将每个错误发送给他们。
What is the easiest way to do this, can you do it within the web.config file?

You should use SmtpAppender
你应该使用 SmtpAppender
<appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">
<to value="[email protected]" />
<from value="[email protected]" />
<subject value="test logging message" />
<smtpHost value="SMTPServer.domain.com" />
<bufferSize value="512" />
<lossy value="true" />
<evaluator type="log4net.Core.LevelEvaluator">
<threshold value="WARN"/>
</evaluator>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%newline%date [%thread] %-5level %logger [%property{NDC}] - %message%newline%newline%newline" />
</layout>
</appender>
<logger name="ErrorLogger">
<level value="Error" />
<appender-ref ref="FileAppender" />
</logger>
<logger name="EmailLogger">
<level value="Error" />
<appender-ref ref="SmtpAppender" />
</logger>
In order to send emails only for an specific error you could do something like this
为了仅针对特定错误发送电子邮件，您可以执行以下操作
try
{
// your logic
}
catch (MySpecificException ex)
{
// I only send emails for exception of type MySpecificException
LogManager.GetLogger("EmailLogger").Error(ex);
}
catch (Exception ex)
{
// Just log to a file for the rest
LogManager.GetLogger("ErrorLogger").Error(ex);
}
