In order to return a value from a VB.NET function one can assign a value to the ‘Functions Name’ or use ‘return value.’
I sometimes see these inter-mixed in the same function. Personally, I prefer the return.
My question is, what is the internal difference, if any, between the two?
There is probably no difference. IIRC, the compiler generated IL converts them both into Return statements unless there is additional usage of a _returnValue variable.
The readability of the FunctionName assignment is poor in my opinion, and an example of a bad VB6 habit. I prefer the _returnValue (NOT RETVAL) variable method also.
