Open up visual studio and then open up this file.

Put a breakpoint in and run the code.

Hoover over the various variables to determine what that illegal character is.

try : if(File.Exists(Server.MapPath ("~/Images/") + "\" + oldFileName))

Programming to simplify, dont look for hard way

Problem solved! oldFileName was empty! Database was empty! It was checking for old filename which didnt return any value, so File.Exists searched for NULL!

heres a code ! Check it if it is correct and my above answer makes sense!
