EF查询分页

static List<T> GetPageList(Func<T,bool> whereLambda,Func<T,object> orderLambda,int pageSize,int pageIndex)
        where T:class
    {
        EFEntities context=new EFEntities();//实例化上下文
        var list=context.Set<T>().where(whereLambda).orderByDescending(orderLambda).Skip((pageIndex-1)*pageSize).Take(pageSize).Select(s=>s);
        return list.ToList(); 
    }
