C# 集合、字典、栈和队列

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            // 定义可变数据组类型
            List<Dog> list = new List<Dog>();
            // 添加数组元素
            list.Add(new Dog("A"));
            list.Add(new Dog("B"));
            list.Add(new Dog("C"));
            list.Add(new Dog("D"));
            list.Add(new Dog("E"));
            list.RemoveAt(1);  // 删除第二个，1表示的是下标
            for (int i = 0; i < list.Count; ++i)
            {
                list[i].ShowName();
            }
        }
        public class Dog
        {
            private string Name;
            public Dog(string name)
            {
                Name = name;
            }
            public void ShowName()
            {
                Console.WriteLine("狗的名字是:" + Name);
            }
        }
    }
}

字典的使用形式：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            // 字典的定义
            Dictionary<string, Dog> dog1 = new Dictionary<string, Dog>();
            // 添加形式
            dog1.Add("A", new Dog("A"));
            dog1.Add("B", new Dog("B"));
            dog1.Add("C", new Dog("C"));
            dog1.Add("D", new Dog("D"));
            // 访问形式
            dog1["B"].ShowName();
        }
        public class Dog
        {
            private string Name;
            public Dog(string name)
            {
                Name = name;
            }
            public void ShowName()
            {
                Console.WriteLine("狗的名字是:" + Name);
            }
        }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            // 调用栈
            Stack<Dog> stack1 = new Stack<Dog>();
            // push进栈操作
            stack1.Push(new Dog("A"));
            stack1.Push(new Dog("B"));
            stack1.Push(new Dog("C"));
            // peek() 查看当前栈顶元素
            stack1.Peek().ShowName();  // 显示"C"
            // 弹出栈顶指针
            stack1.Pop();  // 弹出"C"
            stack1.Peek().ShowName();  // 此时应该显示"B",因为"C"已经被pop()弹出
        }
        public class Dog
        {
            private string Name;
            public Dog(string name)
            {
                Name = name;
            }
            public void ShowName()
            {
                Console.WriteLine("狗的名字是:" + Name);
            }
        }
    }
}

队列的使用:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            // 队列的使用
            Queue<Dog> dog1 = new Queue<Dog>();
            // 进队操作
            dog1.Enqueue(new Dog("A"));
            dog1.Enqueue(new Dog("B"));
            dog1.Enqueue(new Dog("C"));
            // 出队列操作
            dog1.Dequeue().ShowName();  // 先进先出，所以弹出的是"A"
        }
        public class Dog
        {
            private string Name;
            public Dog(string name)
            {
                Name = name;
            }
            public void ShowName()
            {
                Console.WriteLine("狗的名字是:" + Name);
            }
        }
    }
}

栈的使用
