Selenium c# https://baseurl/config/dteg/vt2k/standard/vt2k-dev-standard.txt I want to extract vt2k-dev-standard.txt

when I press an icon in my application, it automatically generates a file and opens its contents in the url in a new tab or current tab whichever way you look at it

https://BASEURL/config/dteg/vt2k/standard/vt2k-dev-standard.txt

I want to read in the full url and extract the last filename and store it in a string. Can you please help me?

Thank you

I haven't tried anything yet. Anything I have tried either gets the previous url in old tab or just simply gets the base url.
