If all you want is a ReadOnly DataTable for reporting or web, try this:

  conn = new SqlConnection(connString);
  string query = "SELECT * FROM Customers";
  SqlCommand cmd = new SqlCommand(query, conn);
  conn.Open();
  SqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
  DataTable dt = new DataTable();
  dt.Load(dr);
