Name

Params

Synopsis

NameValueCollection = Request.Params

The Params collection returns an instance of the NameValueCollection class containing key/value pairs for the QueryString, Form, ServerVariables, and Cookies collections. You can use the Params collection to dump all of these collections to a file or to the browser and to troubleshoot an application or track the form values your application receives, regardless of whether they come via GET (QueryString collection) or POST (Form collection).

Parameters

NameValueCollection

An Object variable of type NameValueCollection.

Example

The example writes the keys and values contained in the Params collection to the browser: 

Sub Page_Load(  )
   Dim Counter1, Counter2 As Integer
   Dim Keys(), subKeys(  ) As String
   Dim ParamColl As NameValueCollection
  
   ' Load Params into NameValueCollection
   ParamColl=Request.Params
   ' Get keys into an array
   Keys = ParamColl.AllKeys
   For Counter1 = 0 To Keys.GetUpperBound(0)
      Message.Text &= "Key: " & Keys(Counter1) & "<br/>"
      ' Get all values under this key
      subKeys = ParamColl.GetValues(Counter1) 
      For Counter2 = 0 To subKeys.GetUpperBound(0)
         Message.Text &= "Value " & CStr(Counter2) & ": " & _
            subKeys(Counter2) & "<br/>"
      Next Counter2
      Message.Text &= "<br/>"
   Next Counter1
End Sub
