黄聪：用ForEach方法对List<T>中对每一个项目调用同一个方法

输

对一个List<T>中每一个对象都进行一个函数操作

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Person graham = new Person("Graham", "Hill");
            Person emerson = new Person("Emerson", "Fittipaldi");

            List<Person> Persons = new List<Person>() { graham, emerson };

            //对Persons中每个对象都执行Action方法
            Persons.ForEach(Action);
        }

        static void Action(Person p)
        {
            Console.WriteLine(p.FirstName + " " + p.LastName);
        }
    }

    public class Person
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }

        public Person(string first, string last)
        {
            FirstName = first;
            LastName = last;
        }
    }
}
