Substitute for Microsoft Data Access ApplicationBlocks obsolete SqlHelper class

问题

It looks that the old SqlHelper class from the Microsoft Enterprise Library has been mostly replaced by the Database class which is included in the new Enterprise Library version 5.

I have a very simple and trivial example:

using Microsoft.ApplicationBlocks.Data;

private void PopulateCheckBoxGroup()
 {
     const string strConnTxt = "Server=(local);Database=DataBindTests;Integrated Security=True;";
     const string strlSql = "select Technology from PreferredTechnology where ParentId = 1";
     CheckBoxList1.DataSource = SqlHelper.ExecuteReader(strConnTxt, CommandType.Text, strlSql);
     CheckBoxList1.DataTextField = "Technology";
     CheckBoxList1.DataBind();

 }

Can you give me just a hint in order to do the same using the new Database abstract class that replaced the SQLHelper? I have looked into the Enterprise Library 5 "Hands On Labs" and there is no mention about it.

thanks in advance.

It's pretty much the same, just varies in its construction, e.g.:

var database = new SqlDatabase("<connection>");
using (var reader = database.ExecuteReader(...))
{

}
