Connecting To Sql2005 Using C#

Help...  I am new to C# and .net and I am trying to build a insert page with a couple of drop down controls where I pull a categoryID and subcategoryID to populate my dropdown controls from a MS sql2005 express database.  I am using a book that only shows how to build the script and access a access database and I am getting this error when trying to pull up the page:

Compiler Error Message: CS0246: The type or namespace name 'OleDbConnection' could not be found (are you missing a using directive or an assembly reference?)

Below is my code and I am not sure what the syntax needs to be when connecting to a ms sql datasource.  Thanks in advanced :)

 

MYCODE:

<%@ Page Language="C#" MasterPageFile="~/main.master" Title="Untitled Page" %>

   
<script runat="server" language="C#">
      OleDbConnection objConn = newOleDbConnection(
        "Server=SIMBA\NETSDK;" +
        "Database=btuniverse;" +
        "User ID=sa;Password=password");
    OleDbCommand objCmd;
    OleDbDataReader objRdr;
   
    void Page_Load() {
        if (!IsPostBack) {
            objConn.Open();
           
            objCmd = new OleDbCommand("SELECT * FROM dbo.tblNewsCategories", objConn);
            objRdr = objCmd.ExecuteReader();
            ddlCategory.DataSource = objRdr;
            ddlCategory.DataValueField = "CategoryID";
            ddlCategory.DataTextField = "CategoryName";
            ddlCategory.DataBind();
            objRdr.Close();
           
            objCmd = new OleDbCommand("SELECT * FROM dbo.tblSubCategories", objConn);
            objRdr = objCmd.Executereader();
            ddlSubCategory.DataSource = objRdr;
            ddlSubCategory.DataValueField = "SubCategoryID";
            ddlSubCategory.DataTextField = "SubCategoryName";
            ddlSubCategory.DataBind();
            objRdr.Close();
           
            objConn.Close();
        }
    }
