How to catch ALL exceptions/crashes in a .NET app [duplicate]

Answer 1

The Global.asax class is your last line of defense. Look at:

protected void Application_Error(Object sender, EventArgs e)

method

Answer 2

I think you should rather not even catch all Exception but better let them be shown to the user. The reason for this is that you should only catch Exceptions which you can actually handle. If you run into some Exception which causes the program to stop but still catch it, this might cause much more severe problems. Also read FAQ: Why does FxCop warn against catch(Exception)?.

Answer 3

it doesn't hurt to use both AppDomain.CurrentDomain.UnhandledException Application.ThreadException

but keep in mind that exceptions on secondary threads are not caught by these handlers; use SafeThread for secondary threads if needed

Answer 4

This article in codeproject by our host Jeff Atwood is what you need. Includes the code to catch unhandled exceptions and best pratices for showing information about the crash to the user.

Answer 5

You can use the AppDomain.CurrentDomain.UnhandledException to get an event.
