Route constraints call the controller method if its not any image

Question

I'm terrible at regex, but anybody can help here. We have redirect all path to one method but we don't want it if path has any images extension.

I have tried but current code is totally fail.

           routes.MapRoute(
                name: "DefaultCMS",
                url: "{*paths}",
                defaults: new
                {
                    controller = "Home",
                    action = "Index",
                    paths = UrlParameter.Optional
                },
                constraints: new { paths = @".*\.(jpeg|gif|jpg|png)(/.)?)" } // this regex only allow if path has this extension.
            );

Edit: to match the opposite of a pattern refer to this SO question

This regex should match any string that ends with ".{extension}" where {extension} is placeholder for one of the extensions you listed:

^.*\.(jpeg|gif|jpg|png)$

Hi elder S, Thank for answer but what if I dont want to match any string if it has .{extension} – Kd Nimavat Sep 03 '21 at 05:28
So you want to match all strings that don't follow the pattern? – Eldar S Sep 03 '21 at 13:50
Yes right, Match all string that doesn't follow the pattern. – Kd Nimavat Sep 04 '21 at 12:00
