Checking if an arbitrary (remote) URL is a file attachment, and extracting it if it is? [Answered]
If I'm given an arbitrary URL (I don't have control over it), how can I check if it appears to be a direct link to a file, and if it is, extract the filename + extension? It's been a little while so I don't remember why I stopped using it, but I tried using
Path.GetFileName()http://example.com/image.png?width=420&height=69image.pngimage.png?width=420&height=69
