get parameters from referrer

Question

Is there any easy way to extract the parameters of the referrer url as contained in Request.UrlReferrer? Is there another way to get the parameters used by the referrer?

Query?blahID=3&name=blah

I am refering to getting blahID and name from the url. It can be done with a bunch of string manipulations, but was hoping there was an easier way.

Answer 1

Use HttpUtility.ParseQueryString from System.Web. Something like this should work:

string blahID = string.Empty;
if(Request.UrlReferrer != null)
{
    var q = HttpUtility.ParseQueryString(Request.UrlReferrer.Query);
    blahID = q["blahID"];
}
