c# - 如何更新Web.config以通过C#通过电子邮件发送错误？

Question

我正在使用Visual Studio 2013，Web服务器正在运行.NET 4，并且在实时服务器上的Web窗体上出现错误，该代码可以在localhost上正常运行。

当我通过本地主机调试我的Web应用程序时，当前是通过电子邮件发送错误，我希望它在运行时(如果可能，还可以在我的本地主机上)向我发送错误。它曾经向我发送来自生产服务器的错误，但是当我开始调试时，它更改了一些设置，但现在不再。

我假设问题出在某个地方，任何人都可以就在哪里寻找问题给出一些一般性想法吗？这是我的web.config中的一些用于异常处理的代码，还有其他一些代码可以帮助您解决问题吗？

如果没有看到更多的配置文件和/或发送电子邮件通知的错误处理代码，我们将无法对您的特定问题提供太多帮助。但是，解决您的问题的另一种方法可能是错误处理/记录/通知框架，例如:
