List <T>是C#中的集合,并且是通用集合。C#列表中使用add和remove方法添加和删除元素。
让我们看看如何Add()

using System; using System.Collections.Generic; class Program { static void Main() { List<string> sports = new List<string>(); sports.Add("Football"); sports.Add("Tennis"); sports.Add("Soccer"); foreach (string s in sports) { Console.WriteLine(s); } } }
输出结果

让我们看看如何Remove()
在C#中使用方法。
using System; using System.Collections.Generic; class Program { static void Main() { List<string> sports = new List<string>(); sports.Add("Football"); // add method sports.Add("Tennis"); sports.Add("Soccer"); Console.WriteLine("Old List..."); foreach (string s in sports) { Console.WriteLine(s); } Console.WriteLine("New List..."); sports.Remove("Tennis"); // remove method foreach (string s in sports) { Console.WriteLine(s); } } }
