using QueryString Property using VB.net

[anoop]

Hello,
I want to write the VB code to extract value from QueryString
property using ASP.Net, the following code should be written in The Form's
Action property.
Dim loop1, loop2 As Integer
Dim arr1(), arr2() As String
Dim coll As NameValueCollection

' Load Form variables into NameValueCollection variable.
coll=Request.QueryString
' Get names of all keys into a string array.
arr1 = coll.AllKeys
For loop1 = 0 To arr1.GetUpperBound(0)
Response.Write("Key: " & Server.HtmlEncode(arr1(loop1)) & "<br>")
' Get all values under this key.
arr2 = coll.GetValues(loop1)
For loop2 = 0 To arr2.GetUpperBound(0)
Response.Write("Value " & CStr(loop2) & ": " &
Server.HtmlEncode(arr2(loop2)) & "<br><br>")
Next loop2
Next loop1
How do I go about.Please hepl me, I am new to .Net.

Thank you
