Using Request.QueryString
 
Posted 15 years ago on 7/17/2007 and updated 12/29/2008
Take Away: Although you can use the generic request collection, as in Request("SomeValue"), for either Request.Form("SomeValue") or Request.QueryString("SomeValue"), it's best to avoid the generic request collection until it's really needed. Use a For Each loop to loop through elements.

Request.QueryString("x") vs. Request("x")

Although you can use the generic request collection, as in Request("SomeValue"), for either Request.Form("SomeValue") or Request.QueryString("SomeValue"), it's best to avoid the generic request collection until it's really needed. The generic request collection causes problems in some circumstances. For example, you cannot call the generic request collection after a BinaryRead.

Looping Through Request.QueryString

Here's an example of looping through the QueryString writing out each key and value pair:

Dim Key
 
For each Key in Request.QueryString
 Response.Write Key & "=" & Request.QueryString(Key)
Next

Display First QueryString Value

The following code snippte will display the first query string value:

If Len(Request.QueryString) > 0 Then
 Response.Write "First value is " & Request.QueryString(1)
Else
 Response.Write "No query string."
End If
