Queue和Stack的区别(队列和栈)

Queue有两个口,那么就是先进新出,而Stack只有一个口,后进先出.

举两个例子说明;

namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            Queue queue1 = new Queue();
            queue1.Enqueue(1);
            queue1.Enqueue("Hello");
            int[] newArr = {9,4,5};
            for (int i = 0; i < newArr.Length;i++ )
            {
                queue1.Enqueue(newArr[i]);
            }
            while (queue1.Count > 0)
            {
                Console.WriteLine(queue1.Dequeue());
            }
            Console.ReadKey();
        }
    }
}

输出结果:
1
Hello
9
4
5

再看用Stack的例子

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            Stack stack = new Stack();
            stack.Push(1);
            stack.Push("Hello");
            int[] newArr = { 9, 4, 5 };
            for (int i = 0; i < newArr.Length; i++)
            {
                stack.Push(newArr[i]);
            }
            while (stack.Count > 0)
            {
                Console.WriteLine(stack.Pop());
            }
            Console.ReadKey();
        }
    }
}

输出结果:
5
4
9
