将对象从对象数组输出到windows窗体中的标签。

using System;
using System.Windows.Forms;

namespace ObjectArrayToLabel
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            // 定义对象数组并初始化对象的属性
            Person[] persons = new Person[]
            {
                new Person("John", 25),
                new Person("Alice", 30),
                new Person("Bob", 35)
            };

            // 遍历对象数组，将属性值拼接成字符串
            string output = "";
            foreach (Person person in persons)
            {
                output += $"Name: {person.Name}, Age: {person.Age}\n";
            }

            // 将拼接好的字符串赋值给标签控件的Text属性
            label1.Text = output;
        }
    }

    // 定义一个Person类，用于存储人员信息
    public class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }

        public Person(string name, int age)
        {
            Name = name;
            Age = age;
        }
    }
}
