全局处理应用程序中的多个try catch块 [英] Handle multiple try catch blocks across the application globally

问题描述

我有一个asp.net c＃应用程序，在生产中运行得非常好。这是一个庞大的项目，几乎每个方法都尝试使用catch块而没有异常处理（catch中没有代码），现在如果发生任何错误而不是调试所有代码并发现异常，我想全局处理它。有什么建议？

I have an asp.net c# application, running pretty good in production. It's a vast project and almost every method has try catch block with no exception handling(no code in catch), now if any error occurs instead of debugging all code and find exception, I want to handle it globally. Any suggestions?

Do not use try-catch without good reason!!! Never!!! Try-catch is very expensive and for that it intended for exceptional errors only...Do not use it as a solution for input validation for instance or to overcome problems of missing files and so on...

If you want to handle all unhandledexceptions in one place utilize the Application_Error method in Global.asax...
