string - Filename pattern matching within .NET

[Sea Sharper]

Hi,

C#, from a FileSystemWatcher I would like to catch all files with a *.*
filter but then inside the event handler compare against a list of wildcards
(eg '*.abc;*.def')

Is there anywhere inside the Framework where I can do something like

Pattern x = new Pattern("*.abc");
if ( x.Matches(strFilename) )
{
//do something
}

Obviously I could just assume the file extensions were being used (and use
Path.GetExtension accordingly), but if a wildcard such as 'xyz??.*' is used
then I havent a hope.

Hope you can help, thanks.

Paul

Hi Sea,

Check out Regex (regular expressions) class.

Thanks Miha,

I had forgotten about Regex, but the Regex syntax is different from filename
wildcards.

I could write a conversion from filename wildcard to regex syntax (eg. ? to
..?) but it would be fragile to change and possibly buggy.

Is there any other system?

Thanks.
