    Private Sub Page_Load(sender As Object, e As EventArgs)

        ' Create a string to contain the paramaters'
        ' information.
        Dim paramInfo As String = ""

        Dim i, j As Integer

        ' Obtain a reference to the Request.Params
        ' collection.
        Dim pColl As NameValueCollection = Request.Params

        ' Iterate through the collection and add
        ' each key to the string variable.
        For i = 0 To pColl.Count - 1

            paramInfo += "Key: " + pColl.GetKey(i) + "<br>"

            ' Create a string array that contains
            ' the values associated with each key.
            Dim pValues() As String  = pColl.GetValues(i)

            ' Iterate through the array and add
            ' each value to the string variable.
            For j = 0 To pValues.Length - 1

                paramInfo += "Value:" + pValues(j) + "<br><br>"

            Next j
        Next i

        ' Set a Label's Text property to the values
        ' contained in the string variable.
        lblValues.Text = paramInfo
    End Sub

    <form runat="server">
