How to copy multiple files with same extension in .NET


In VB 6, I was able to copy all files from a folder with a .txt extension to a backup folder.  I used CopyFile and the *.txt to do it.  I do not believe you can use the wildcard symbol with the System.IO.File Copy member.

I'm sure there is a simple way to do this, but I have not discovered it.

I use GetFiles method of Directory Object with wildcard, and loop thru it.
