c#数组成员数量的问题

Question

class Program
    {
        public struct scoreInformation
        {
            public int number;
            public int time;
            public int counter;
        }
        static void Main(string[] args)
        {
            scoreInformation[] scoreStatistic = new scoreInformation[]
            {
                new scoreInformation(){ number=1, time=2, counter=3 },
                new scoreInformation(){ number=2, time=2, counter=3 },
                new scoreInformation(){ number=3, time=2, counter=3 },
            };            var result = scoreStatistic.FirstOrDefault(x => x.number == 1);
            Console.WriteLine(result.number);//输出1
        }
    }

Answer 1

1：达到未知成员数量而可以使用的目的  —>      使用ArrayList
2：遍历集合，object  as 变量类型，赋值；

Answer 2

List<scoreInformation> L=new List<scoreInformation>();
L.Add(new scoreInformation() {number=1,time=1,counter=1 })
