Random Number from value list returned by a DataReader

Hi

My datareader is generating a list of numbers (integers) and I want to randomly pick one of the UserID values from the list and assign it to a label control.  I've placed the values for dr("UserID") into an ArrayList thinking this might be the best approach (maybe not) and now I just need to randomly pick one from the ArrayList, myList.  

Dim myList As New ArrayList
       
        Try
            con.Open()
            cmd.Connection = con
            dr = cmd.ExecuteReader()
           
            With dr
                If .HasRows Then
                    While .Read
                        myList.Add(dr("UserId"))                      
                    End While
                End If
            End With
