如何通过dateTimePicker ValueChanged c#计算年龄、年、月和日

using System;
using System.Windows.Forms;

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

        private void dateTimePicker1_ValueChanged(object sender, EventArgs e)
        {
            DateTime selectedDate = dateTimePicker1.Value;
            DateTime currentDate = DateTime.Now;

            TimeSpan difference = currentDate - selectedDate;

            int ageInYears = (int)(difference.TotalDays / 365.25);
            int ageInMonths = (int)(difference.TotalDays / 30.436875);
            int ageInDays = (int)difference.TotalDays;

            // 输出计算结果
            MessageBox.Show($"年龄：{ageInYears}岁\n年：{ageInYears}年\n月：{ageInMonths}个月\n日：{ageInDays}天");
        }
    }
}
