title: How can I find a variable or specific parts of the sourcecode from websites in C#
body: <p>I want to try something out and for that I would want to get a variable / part of the sourcecode in C# and display it. For example on a youtube page every ** seconds get the sourcecode of the page and display the subscriber count.
  I don't know if it works, but if, then how? I looked through many different pages on the internet and never found something :/
  Thanks!</p>
