C#编程-100：List泛型学习

集合与数组比较：

（1）长度可以改变

（2）添加数据时，不必考虑具体类型

using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace GenericTest
{
    class Program
    {
        static void Main(string[] args)
        {
            List<</span>int> list = new List<</span>int>();
            list.Add(1);
            list.Add(2);
            list.Add(3);
            list.AddRange(new int[]{4,5,6,7,8});
            list.AddRange(list);//将自身作为参数添加到列表
 
            Console.WriteLine("======输出=======");
            for(int i=0;i
                Console.WriteLine(list[i]);
             
            Console.WriteLine("======反转=======");
            list.Reverse();
            for (int i = 0; i < list.Count; i++)
                Console.WriteLine(list[i]);
             
            Console.WriteLine("======排序大到小=======");
            list.Sort();
            for (int i = 0; i < list.Count; i++)
                Console.WriteLine(list[i]);
             
            Console.WriteLine("======插入=======");
            list.Insert(3,100);
            for (int i = 0; i < list.Count; i++)
                Console.WriteLine(list[i]);
 
            Console.WriteLine("======删除=======");
            list.Remove(3);
            for (int i = 0; i < list.Count; i++)
                Console.WriteLine(list[i]);
 
            Console.WriteLine("======数组与列表互转=======");
            int[] nums = list.ToArray();
            List<</span>int> list2 = nums.ToList();
            Console.ReadKey();
        }
    }
}
