In tools/exceptions, I've set the option that the debugger stops when an exception is thrown. Whether it is caught or not .
How do I exclude an exception of that rule? Somewhere in my code there is a caught exception that is part of the program logic. So I obviously don't want that exception to stop the debugger each time it is hit.
Example: I want to ignore the nullreference exception (which is caught) on line 344 . I want to stop at all other exceptions
In Visual Studio you can specify exactly which exceptions you want to halt on. Go to Debug > Exceptions and fold out the relevant branch. From here you can check/uncheck the exceptions you want.
You are not able to single out an exception thrown at a specific place in your code. You are however able to disable exeptions of a specific type.
If your own code throws the exception in question, i would make it a custom exception, derived from whatever fits, and then disable debug breaking on this derived type.
Disabling system exeptions as NullReferenceException will affect the entire system, which of course isnt desirable during development.
Note that there is two kinds of break-behaviors for exceptions:
You could remove the check in 'Thrown' for the NullReferenceException which will give you the benefit of not breaking each time your system passes the line in question in your code, but still breaking if you have some unhandled NullReference expection occuring in other parts of the system.
If I recall correctly you can use a DebuggerStepThrough attribute on the method that contains the code you don't want exception to fire. I suppose you can isolate the code that fires the annoying exception in a method and decorate it with the attribute.

That don't work Chris. Tested with VS2008. DebuggerStepThrough works only when stepping into method/class, exception catching ignore them.
