Just to clarify:
The values you want are on a website and you do not have access to their data.
You are using C# and you want a way to "scrape" the site for values?

Is that correct?

Not always a trivial task!
Have a look at some of the existing articles on the subject: Google "Site Scraping c# site:codeproject.com"[^]

Please see the comment to the question by Andy Lanng. It looks like his assumptions are correct.
What you need called Web scraping: http://en.wikipedia.org/wiki/Web_scraping[^].

Basically, you may need two things: HttpWebRequest and, pretty usually, something to parse HTML you download. Please see my past answers:
How to get the data from another site[^],
get specific data from web page[^],
Performing a some kind of Web Request and getting result[^].

I would add another advice for HTML parsing: use HTML Agility Pack:

Solution 3

Try this one....

C#

string _getUri = HttpContext.Current.Request.Url.AbsoluteUri;
          string[] strArray = _getUri.Split('/');
          string ReqValue = strArray[3];
