Get HTML Code from a website after it completed loading

Question

I am trying to get the HTML Code from a specific website async with the following code:

var response = await httpClient.GetStringAsync("url");

But the problem is that the website usually takes another second to load the other parts of it. Which I need, so the question is if I can load the site first and read the content after a certain amount of time.

Sorry if this question already got answered, but I didn't really know what to search for.

Thanks, Twenty

Edit #1

If you want to try it yourself the URL is http://iloveradio.de/iloveradio/, I need the Title and the Artist which do not immediately load.

You are on the wrong direction. The referenced site has playlist api which returns json. you can get information from :

http://iloveradio.de/typo3conf/ext/ep_channel/Scripts/playlist.php

Edit: Chome Inspector is used to find out Playlist link
