尝试以下操作：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            List<Person> people = new List<Person>();

            DataTable dt = new DataTable();
            dt.Columns.Add("firstname", typeof(string));
            dt.Columns.Add("lastname", typeof(string));
            dt.Columns.Add("age", typeof(int));

            foreach (Person person in people)
            {
                dt.Rows.Add(new object[] { person.firstName, person.lastName, person.age });
            }

        }
    }
    class Person
    {
        public string firstName { get; set; }
        public string lastName { get; set;  }
        public int age { get; set; }

        public Person(string firstName, string lastName, int age)
        {
            this.firstName = firstName;
            this.lastName = lastName;
            this.age = age;
        }
    }
}
