如果在特定程序集中抛出异常，Serilog会发送邮件

Question

我正在开发一个包含多个程序集的asp.net core（2.2）应用程序。对于日志记录，我使用serilog for asp.net core。现在需要在抛出异常时发送邮件。关键是：只有在特定程序集中抛出异常时才会发送电子邮件。有没有办法通过serilog电子邮件接收器实现这一目标？谢谢。

Answer 1

它不是特定于电子邮件接收器，而是任何记录器配置。有很多例子，请参阅这个答案。也可以过滤类和命名空间，并且可以通过其他接收器记录来自其他程序集的异常。喜欢滚动文件。 Filter Serilog logs to different sinks depending on context source?

以下是满足要求的appsettings.json的配置：
