C# 把数字转换成链表

例如：123456转换成 1 -> 2 -> 3-> 4-> 5-> 6

        static LinkedList<int> CovertIntToLinkedList(int num){Stack<int> stack = new Stack<int>();LinkedList<int> result = new LinkedList<int>();while (num!=0){stack.Push(num % 10);num = num / 10;}while (stack.Count>0){result.AddLast(stack.Pop());}return result;}static LinkedList<int> CovertIntToLinkedList2(int num){LinkedList<int> result = new LinkedList<int>();int[] intArr = new int[num.ToString().Length];int i = 0;while (num!=0){intArr[i] = num% 10;num /=10;i++;}for (int j = intArr.Length-1; j >=0; j--){result.AddLast(intArr[j]);}return result;}
