I think, this code is a result of Reflector disassembling :-D

Yeah! Like he said. Yet another .NET feature I've not encountered before, good to know. Henry Minute Do not read medical books! You could die of a misprint. - Mark Twain Girl: (staring) "Why do you need an icy cucumber?" “I want to report a fraud. The government is lying to us all.”

If you see the code, this part stackTrace = new StackTrace(); stackFrame = stackTrace.GetFrame(2); is in a try-catch block that catchs all the exceptions, also, methodBase is checked for null, so the exception is not thrown there. Also, the exception is a null reference generated in the posted method, not in any method called by it, meaning that we tried to call methods on some variable or property that was null.
