C# 如何初始化对象数组

Answer 1

namespace Test{
   
    using System;
    using System.Collections.Generic;
    
    internal class Person {
        public Person() {}
        public Person(string n,int a) {
            this.Name = n;
            this.Age = a;
        }
        public string Name { get; set; }
        public int Age { get; set; }
    }
    
    class Program{
        static void Main(string[] args){
           
            // 方案一：泛型集合初始化器
            var person = new List<Person>
            {
                new Person{Name="张三",Age=18},
                new Person{Name="李四",Age=19}
            };

            foreach (Person p in person)
            {
                Console.WriteLine("{0},{1}",p.Name,p.Age);
            }
            Console.WriteLine();

            // 方案二：直接初始化对象数组

            Person[] person2 = new Person[]{
                new Person("张三2",18),
                new Person("李四2",19)
            };

            Console.ReadKey();
        }
    }
}
