No but I will think they will generate the same IL code, but never checked, I use the CINT(), CDATE() and all the other C functions instead of convert, but that just cause I got use to.
I know that they say that DirecCast can yeld better performance then CTYPE funtion when converting from and to objects.
you know that you have also a TryCast function that what it does is instead of raising an error if the conversion can't be perform it returns nothing instead can be usefull is some case when you want to return nothing if a conversion can't be perform.
