OpenFileDialog: Filter specific number pattern?

[jasonp45]

I want to set the OpenFileDialog filter to something like "info.9999", where the 9999 can be any 4 numbers. Is there a wildcard or formatting option to allow this?

I don't want the filter to be "info.*", because I'm looking specifically for files with four numbers after the period.

Thanks.

I don't think you can do this. If you must have this functionality, you'll probably need to create your own form that you can use like an OpenFileDialog, that uses regular expressions to apply filters.

If the users will know what four numbers they are looking for up front, then I would just filter for *.1234 or *.5678 based on whatever their input is.

Hope this helps,

Alex

I finally found a reference to it (link)...there is an additional wildcard character available: ?. It allows you to look for "zero or one character", so I can do something like "info.????". However this won't differentiate between numbers and any other type of character.
