Way to get unique filename if specified filename already exists (.NET)

Question

Is there a built in .NET function to get a unique filename if a filename already exists? So if I try and save MyDoc.doc and it already exists, the file will sav

Answer 1

I don't know, but it's not hard to build one yourself:

if filename does not exists then 
    save file as filename
else
n = 1
while filename(n) exists: 
    n += 1
save file as filename(n)
