1、创建队列

cs 复制代码

namespace Testmain
{
    public class StackQueue
    {
        QNode Front = new QNode(-1);
        QNode Rear = new QNode(-1);
        QNode curNode;
        public StackQueue(int data)
        {
            curNode = new QNode(data);
            if (Front.next == null)
            {
                Front.next = curNode;
                Rear = curNode;
            }
        }
        public StackQueue()
        {

        }

        public void enQueue(int data)
        {
            curNode = new QNode(data);
            if (Front.next == null)
            {
                Front.next = curNode;
                Rear = curNode;
            }
            else
            {
                Rear.next = curNode;
                Rear = curNode;
            }
        }

        public int deQueue()
        {

            if (Front.next == Rear)
            {
                Front.next = Rear.next;
                Rear.Data = -1;
                Rear = Front;
                return -1;
            }
            else
            {
                int data = Front.next.Data;
                Front.next = Front.next.next;
                return data;
            }


        }
    }
}

2、队列节点

cs 复制代码

namespace Testmain
{
    public class QNode
    {
        public int Data;
        public QNode? next;
        public QNode(int data)
        {
            this.Data = data;
            next = null;
        }
    }
}

3、程序入口

cs 复制代码

using System;
namespace Testmain
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                StackQueue stackQueue = new StackQueue(1);
                stackQueue.enQueue(2);
                stackQueue.enQueue(3);
                stackQueue.enQueue(4);
                stackQueue.enQueue(5);
                Console.WriteLine(stackQueue.deQueue());
                Console.WriteLine(stackQueue.deQueue());
                Console.WriteLine(stackQueue.deQueue());
                Console.WriteLine(stackQueue.deQueue());
                Console.WriteLine(stackQueue.deQueue());

            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

        }

    }
}
