[dba-VB] Parsing strings

I am trying to parse a string.  I notice that the string object has many 
methods but it does not seem to have the left, mid and right functions 
that vba has.

If I want to split a file name into name and extension how would you do 
it?  I am just use the existing string functions that we all know and 
love but am wondering if there is a better (.Net) way.

Thanks,
