在使用CsvHelper时，如何从C#动态对象中获取属性名和属性值？

using CsvHelper;
using System;
using System.Collections.Generic;
using System.Dynamic;
using System.IO;

public class Program
{
    public static void Main()
    {
        // 创建一个动态对象
        dynamic person = new ExpandoObject();
        person.Name = "John";
        person.Age = 30;
        person.Email = "john@example.com";

        // 使用CsvHelper将属性名和属性值写入CSV文件
        using (var writer = new StreamWriter("output.csv"))
        using (var csv = new CsvWriter(writer))
        {
            // 获取动态对象的属性信息
            var properties = person.GetType().GetProperties();

            // 写入属性名
            foreach (var property in properties)
            {
                csv.WriteField(property.Name);
            }
            csv.NextRecord();

            // 写入属性值
            foreach (var property in properties)
            {
                csv.WriteField(property.GetValue(person));
            }
            csv.NextRecord();
        }
    }
}
