Matching file names

| Hi,
I was looking to figure out if .Net had a built in class for matching
files extensions. For example, the user will specify the accepted file
extensions as follow: "*.pdf;*.doc;*.wp". My code needs to verify that
the file format meets the criteria.
How can I do this? Thank you....

| I wrote a small utility method that changed traditional file patterns
into Regex regular expressions. For example:
*.pdf becomes .*\.pdf
Allowing several file extensions can also be expressed in Regex. Once
you've translated the file pattern into a regular expression, just use
the Regex classes to match it against user input, or whatever.
