A convenient wrapper class to get file info

If you have worked with file information in .NET, you have surely run into the fact that SOME of the information is gotten from the FILE class and some from the FILEINFO class, which can get a little confusing. To simplify access to file information, I created this wrapper class called FileStats: the code shows you how to create a new object by sending a full path and name (e.g. "C:\try\test.txt") and then you have an object with parameters that give you the information you need most about files: PathAndName, Name, SizeInBytes, Extension, CreationDateTime, and LastModifiedDateTime. If the file does not exist, then an FileNotFoundException is thrown. This code sample shows how to handle it as well. Enjoy.
