Question

Asp.net has turned out to be alot easier to use than PHP (so far). However, I have been searching for a while and simply cannot figure this out. How do I get the variables that are contained in the url of my page (that originate from a form that had the method ‘GET’) and utilize them?

For example, my page would be http://www.example.com/index.asp?somevariable=something

How would I get the value of somevariable?

You can use what ybo stated, but it isn’t complete (for VB at least). That alone could leave to a null reference exception being thrown. You want to cast (i.e. TryParse) the values, and handle any empty parameters that your expected to contain a value:

Dim itemId As Integer Dim itemType as String  If Not Integer.TryParse(Request.QueryString('i').ToString, itemId) Then     itemId = -1 ' Or whatever your default value is Else     ' Else not required. Variable itemId contains the value when Integer.TryParse returns True. End If  itemType = Request.QueryString('t').ToString ' <-- ToString important here!
