Retrieve GET variables from URL in ASPX

Question

What's the easiest / standard way to retrieve the GET (in URL) variables passed to a .aspx (VB) page?

Here is an example from SO on looping through the GET postback values. [http://stackoverflow.com/questions/562943/looping-through-a-request-querystring-in-vb-net](http://stackoverflow.com/questions/562943/looping-through-a-request-querystring-in-vb-net) — Zachary, Jun 23 '09 at 16:08

You can use the following:

string value = Request.QueryString("hello");

Value will be goodbye

or

foreach(string key in Request.QueryString)
{
    Response.write(Request.QueryString(key))
}

I get a syntax error when using [ ] but not when using ( ) – Clay Nichols Nov 23 '15 at 17:08

@ClayNichols same here. `Request.QueryString["hello"]` doesn't work. `Request.QueryString("hello")` does. – tresf Dec 22 '16 at 16:09
I took the liberty to change [ ] to ( ). The latter is VB.NET syntax which the question is about. – Paul B. Jan 16 '20 at 09:18
Dec 2020 and this is not working for me. Just getting a blank line when trying to log value. Should this still work? – Cole Perry Dec 14 '20 at 14:44

Look at the Request.QueryString collection

if you have a path :

www.stackoverEvan.com/question/directory-lookup.asp?name=Evan&age=16

If you do :

Hi ,  <%= Request.QueryString("name") %>.  
Your age is  <%= Request.QueryString("age") %>.

Output :

Welcome, Evan. Your age is 16

But as your specifying it's in VB the optimal way would be like :

Path :

http://localhost/script/directory/NAMES.ASP?Q=Evan&Q=Bhops

Code :

--- Names.asp --- 
<% 
  For Each item In Request.QueryString("Q") 
    Response.Write Request.QueryString("Q")(item) & "<BR>" 
  Next 
%>

Output :

Evan
Bhops
