What is the difference between File and FileInfo in C#?

Question

I\'ve been reading that the static methods of the File Class are better used to perform small and few tasks on a file like checking to see if it exists and that

Answer 1

Recently I faced problem with File.Exist, I hate this function. After than I've used Fileinfo class Exist function then my program works correct.

Actually what happen in development enviornment File.Exist works well but when it goes to live environment this function is blocking the file object due to that reason I am getting the error access denied and not able to use the file.

This is my learning. I will never used File.Exist method best is to create the object and then use it. Be aware to use static methods.
