问题 I know that in ASP.NET people typically put a protected method called "Application_Error" in their global.asax file inorder to handle say, logging of exceptions.

Is it an ASP.NET MVC best practice or not? 回答1: You should be using the Exception Filter to handle exceptions in your controllers. You do this by adding the [HandleError] attribute to the controller action. Further information can be found at:

问题 I've created a small C# winforms application, as an added feature I was considering adding some form of error logging into it. Anyone have any suggestions for good ways to go about this? This is a feature I've never looked into adding to previous projects, so I'm open to suggestions from Developers who have more experience. I was considering something along the lines of writing exceptions to a specified text file, or possibly a database table. This is an application that will be in use for a

This is to avoid duplicating messages like: mylogger.critical("something failed") print "something failed" 回答1: All logging output is handled by the handlers; just add a logging
