Decode and RequestQueryString

My URL is 

www.domainname.com/default.aspx?l=en&t=32600483-1618-4f09-9a86-c12de4dafc7b

I would love to read the QueryString value of t. So i can parse it as GUID.

Unfortunatelly that & thing, seems to mess things up.

How can i parse the value of the t Query string?

My URL is

I hope you realize that this is not a valid URL. This is a HTML encoded string. Do not confuse with an URL. URLs should be properly URL encoded, not HTML encoded. And since you start with something invalid your only chance is to use some ugly string parsing/regex to extract the necessary information. Since this looks like an HTML encoded string you could HTML decode it first:

var myUrl = "http://www.domainname.com/default.aspx?l=en&t=32600483-1618-4f09-9a86-c12de4dafc7b";
myUrl = HttpUtility.HtmlDecode(myUrl);
var values = HttpUtility.ParseQueryString(myUrl);
var t = values["t"];

But I repeat once again: don't do this: tackle the problem at its root. And the root of your problem is the origin of this URL. So if you have control over the generation of this URL then fix it so that you can have a valid URL that you could easily work with with the built-in methods. If you don't have control over the generation of the URL then notify the author of the code that he has a bug in it and ask him to fix it because he has provided you a non-properly encoded URL and you are obliged to use some ugly string parsing mechanisms to extract the information from it.
