Is there any way to get the file extension from a URL

Question

I want to know that for make sure that the file that will be download from my script will have the extension I want.

The file will not be at URLs like:

Answer 1

Here is my solution:

if (Uri.TryCreate(url, UriKind.Absolute, out var uri)){
    Console.WriteLine(Path.GetExtension(uri.LocalPath));
}

First, I verify that my url is a valid url, then I get the file extension from the local path.
