Deleting files using wildcards

I know I can use code like follows to delete a file:

My.Computer.FileSystem.DeleteFile(File123.TAB",
FileIO.UIOption.OnlyErrorDialogs,
FileIO.RecycleOption.DeletePermanently)

How can I delete all files matching text including wildcard(s)? For
example, how can I delete all files beginning with "File123" -->
"File123.*"

If you recursively search the directory you could quite easily use a regular
expression to identify each file and then use DeleteFile to delete it.

DirectoryInfo.GetFiles will do the first part of this for you (I only
know this by looking at Reflector's output for Kill, mind...)

Shell """%comspec%"" /c del ""File123.*"""

Or try Kill("File123*.*")
