File.Delete() versus FileInfo.Delete()

Is there much of a difference between using the static methods of the File object as opposed to creating a new FileInfo object and calling those methods?

Almost there are no difference. Both delete the file if exists and throw an exception if it doesn't exist.

It depends. If you are performing a single operation use the File class and if you are performing multiple operations on the same file, use FileInfo.

EDIT: I made this point as my understanding is that the File class's static methods will always check for the security. But if you are re-using the instance of FileInfo, the methods will do the security check only for the first time and not on each subsequent calls.

Nope, they're basically the same thing.

The only difference is that File must resolve the specified path (assuming it is relative), while the FileInfo should have already have the resolved path.

i hope this will helps you ...

IO.FileInfo provides instance methods for the creation, copying, deletion, moving, and opening of files, and aids in the creation of System.IO.FileStream objects. This class cannot be inherited.

that means, you need to create instance/object of FileInfo to accomplish this processes.
