這篇想要來寫鏈表～因為一開始看到不知道是甚麼

原來是鏈表ＬＩＳＴ
感覺很專業～那就來了解一下

先聲明裏面有四個整數:

using System;
using System.Collections.Generic;

namespace HelloWorld2
{
     class Program
    {
        public static void Main(string[] args)
        {
            List <int> userAgeList = new List <int> { 11,21,31,41};

        }
    }
}

當要選第一個就是0時，

using System;
using System.Collections.Generic;

namespace HelloWorld2
{
     class Program
    {
        public static void Main(string[] args)
        {
            List <int> userAgeList = new List <int> { 11,21,31,41};

            userAgeList[0];

        }
    }
}

當要第2個位置加入51

using System;
using System.Collections.Generic;

namespace HelloWorld2
{
     class Program
    {
        public static void Main(string[] args)
        {
            List <int> userAgeList = new List <int> { 11,21,31,41};

            userAgeList.Insert(2,51);

            Console.WriteLine(userAgeList);

        }
    }
}

把裡面有51的取出來

using System;
using System.Collections.Generic;

namespace HelloWorld2
{
     class Program
    {
        public static void Main(string[] args)
        {
            List <int> userAgeList = new List <int> { 11,21,31,41};

            userAgeList.Insert(2,51);

            userAgeList.Remove(51);

            Console.WriteLine(userAgeList);

        }
    }
}

把裡面有第3個位置取出來

using System;
using System.Collections.Generic;

namespace HelloWorld2
{
     class Program
    {
        public static void Main(string[] args)
        {
            List <int> userAgeList = new List <int> { 11,21,31,41};

            userAgeList.Insert(2,51);

            userAgeList.RemoveAt(2);

            Console.WriteLine(userAgeList);

        }
    }
}
