//獲取商品分類信息返回    public static DataTable GetSortList()    {        string strsql = "select * from sort_info";        return db.ds(strsql);    }在加載頁(yè)面直接用類名調(diào)用GetSortList()綁定到gridview控件做法：DataTable dt=Sort.GetSortList();            this.gridview.datasoucre=dt;            this.gridview.databind(); 問(wèn)題：為啥在調(diào)用方法時(shí),Sort.下面沒(méi)有g(shù)etSortList()方法呢？
