C# 对象到数组

将C#对象转换为数组的简介

csharp
using System;
using System.Collections.Generic;
using System.Linq;
class Program
{
    static void Main()
    {
        // 创建一个对象集合
        List people = new List
        {
            new Person { Name = "John", Age = 30 },
            new Person { Name = "Jane", Age = 25 },
            new Person { Name = "Bob", Age = 40 }
        };
        // 使用LINQ将对象集合中的年龄提取为数组
        int[] ages = people.Select(p => p.Age).ToArray();
        // 打印数组元素
        foreach (var age in ages)
        {
            Console.WriteLine(age);
        }
    }
}
// 定义一个简单的Person类
class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}
