Questions about AuthorizationRules.AllowExecute

FrankM posted on Thursday, October 02, 2008

Does this syntax only work for instance method? If yes, what's the suggested way to if I want to do the similar thing to protect static method?
I have to call CanExecuteMethod(methodName) in my instance method to take advantage of the role setting set by AllowExecute() earlier. Is this kind of unnecessary?
What's the reason the old CanExecuteMethod() (no methodName in parms) become obsolete?

Thanks.

For #3 - it is probably the same reason that the no parameter version of CanReadProperty was made obsolete. They relied on walking a stack trace to locate the property name for you. It turns out that is unreliable. So you have to provide the name in your code.

Thanks Joe, that means the code shown in another post is not stable?

string methodName = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod().Name.Substring(4);

Correct, this code is not reliable. It may work most of the time, but not 100 % of the time.
