I often need to obtain the name of the current property of method, and I have historically used reflection for this. However, I recently ran across the CallerMemberName attribute. This lead me to create the following utility function:
Public Shared Function GetMethodOrPropertyName( <CallerMemberName> Optional memberName As String = Nothing) As String
The key here is that I do not specify the memberName parameter when I call the function, so the compiler fills it in for me. (That's what the attribute is for.) Now I can call this function whenever I need the current method's name. NO custom reflection code required.
