ASP.NET VB Page Generation Time

I'm trying to incorporate into my web pages who long the server took to generate the requested information. So far, I have had no luck on Google or any other developer forums. Below is some code I am working on but I am getting the error message BC30002: Type 'System.Diagnostics.Stopwatch' is not defined.

Code:

---


<%@ Page Language="vb" %>
<%@ Import Namespace="System.Data" %>
<%@ Import Namespace="System.Web.UI.Page" %>
<%@ Import Namespace="System.Diagnostics.Stopwatch" %>

<script runat="server">

dim sw as System.Diagnostics.Stopwatch =
System.Diagnostics.Stopwatch.StartNew()

Protected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)

Me.Label1.Text = sw.ElapsedSeconds
MyBase.Render(writer)

End Sub

</script>

System.Timers.Timer

I tried to import System.Timers into the Namespace but still no go. Could you please provide some example code?

Do you actually get any intellisense when you code like that? Why aren't you using a codebehind?

I've amended my post. It should be System.Timers.Timer. If you can't find it, add a reference to your project and see if there's a DLL called System.Timers, because I think it should be there by default anyways.
