using (var db = new ExpenseDataClassesDataContext(ConfigurationManager.ConnectionStrings["ExpenseConnStr"].ToString()))
{
    var records =
    from rc in db.ClaimHeader
    where rc.UserName == Session["UserName"].ToString() && rc.Status != "De"
    select new
    { rc.指定項目1, rc.指定項目2
    };

   //
  foreach (var r in records)
  {
     Response.BinaryWrite("");
  }
}
