泛型集合List（C#）

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

 namespace ListDemo
 {
 class Program
 {
 static void Main(string[] args)
 {
 //泛型集合的基本使用
 List<int> scoreList = new List<int>();
 scoreList.Add();
 scoreList.Add();
 scoreList.Add();
 scoreList.Add();
 scoreList.Add();
 //List<string> nameList = new List<string>();
 scoreList.Insert(, );
 //获取元素总数
 Console.WriteLine("获取元素总数:"+scoreList.Count );
 Console.WriteLine("_________________");
 //Console.ReadLine();
 //遍历集合
 Console.WriteLine("遍历输出在第一种方法:");
 foreach (int score in scoreList)
 {
 Console.WriteLine(score);
 }
 Console.WriteLine("_________________");
 Console.WriteLine("遍历输出在第二种方法:");
 for (int i = ; i < scoreList.Count; i++)
 {
 Console.WriteLine(scoreList[i]);
 }
 //删除一个元素
 Console.WriteLine("_________________");
 Console.WriteLine(" 删除一个元素");
 scoreList.Remove();
 scoreList.Remove();
 for (int i = ; i < scoreList.Count; i++)
 {
 Console.WriteLine(scoreList[i]);
 }
 Console.WriteLine("_________________");
 Console.WriteLine("清除所有元素");
 scoreList.Clear();
 Console.WriteLine("获取元素总数:" + scoreList.Count);
 Console.ReadLine();
 }
 }
 }
