The type or namespace name 'DataSet' could not be found

I found my error below: <%@Import!!!!!!!
this question will be left for reference.
sorry,


The type or namespace name 'DataSet' could not be found (are you missing a using directive or an assembly reference?)

WHY WHY WHY? I have copied out a simple example from a book,

<%@ Page language = "C#"  runat="server" %>
<%Import Namespace = "System.Data" %>
<%Import Namespace = "System.Data.OleDb" %>
<%Import Namespace = "System.Xml" %>


<script language = "C#"  runat="server">
     void Page_Load()
     {

               string xmlfile = @"C:\inetpub\wwwroot\begaspnet\ch02\artists.xml";
               DataSet DataSet1 = new DataSet();
               DataSet1.ReadXml(xmlfile);
               DataGrid1.DataSource= DataSet1;
               DataGrid1.DataBind();
     }  
</script>

<html>
  <head>
    <title></title>
  </head>
  <body>
  <asp:DataGrid id = "Datagrid1" runat = "server" />
  </body>
</html>

Qualify it with the full namespace.. System.Data.DataSet .. and to answer Andrews Q.. yes c# is using System.Data and vb is Imports System.Data .. but try using the full namespace.. that might help
