将数组中指定数量的元素移动数组后面的实现代码

如下所示：

        static void main()
        {
            int[] array = { 1, 2, 3, 4, 5, 6, 7 };
            movenumberarraytoend(array, 3);
        }
        static void movenumberarraytoend<t>(ilist<t> arraylist, int num)
        {
            if (arraylist.count < = 0 || arraylist.count < num)
            {
                throw new rankexception();
            }
            var query = (from number in arraylist
                         orderby number descending
                         select number).take(arraylist.count - num).concat(arraylist.take(num));
            query.tolist().foreach(q => console.writeline("{0}", q));
        }
