C# How to get a QueryString value from the UrlReferrer

To get a QueryString value from the previous pages URL (aka: the UrlReferrer) you can use HttpUtility.ParseQueryString.

Like this!

NameValueCollection nameValueCollection = HttpUtility.ParseQueryString(Request.UrlReferrer.Query);
string keyword = nameValueCollection["kw"];

“And that’s all I have to say about that.”
