我是新手，我看了C#的一些教程，可是我不太懂类，有没有可以给我讲解下~

看书吧

这个好说，变量，构造函数和成员函数，还有注意静态与非静态的区别就好！

給你一個最簡單的:

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

namespace LINQ_EX1
{
    class Program
    {
        static void Main(string[] args)
        {
              // CREATE ARRAY TO FOR TESTING
              Person[] people = {
              new Person { Name="Allen Frances", Age=11},
              new Person { Name="Burke Madison", Age=50},
              new Person { Name="Connor Morgan", Age=59},
              new Person { Name="David Charles", Age=33},
              new Person { Name="Everett Frank", Age=16}
            };

            foreach (var newPeople in people)
            {
                Console.WriteLine("{0} is {1} years old",
                   newPeople.Name,
                   newPeople.Age
                   );
            }

            Console.ReadLine();
        }
    }

    /*================================
    *
    *           NEW DATA OBJECT CLASS PERSON FOR SYSTEM TEST
    *
   ================================ */
    public class Person
    {
        public string Name{get; set;}
        public int Age{get; set;}
    }
}

再來,為它加點意義:

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

namespace LINQ_EX1
{
    class Program
    {
        static void Main(string[] args)
        {
              // CREATE ARRAY TO FOR TESTING
              PersonB[] people = {
              new PersonB { Name="Allen Frances", Age=11},
              new PersonB { Name="Burke Madison", Age=50},
              new PersonB { Name="Connor Morgan", Age=59},
              new PersonB { Name="David Charles", Age=33},
              new PersonB { Name="Everett Frank", Age=16}
            };

            // USE LINQ TO CHECK THE ITEMS WHICH NEEDED TO UPDATE
            var query = from myPerson in people
                        where myPerson.Age == 11
                        select myPerson;

            // UPDATE OR ADD NEW VALUE INTO THAT OBJECT
            foreach (var item in query)
                item.otherValue = "<<<Allen FUXK>>>";


            foreach (var newPeople in people)
            {
                Console.WriteLine("{0} is {1} years old, and their new value is {2} ...",
                   newPeople.Name,
                   newPeople.Age,
                   newPeople.otherValue
                   );
            }

            Console.ReadLine();
        }
    }

    /*================================
    *
    *           NEW DATA OBJECT CLASS PERSON FOR SYSTEM TEST
    *
   ================================ */
    public class Person
    {
        public string Name{get; set;}
        public int Age{get; set;}
    }

    public class PersonB: Person
    {
        public string otherValue{get; set;}
    }
}

Object在C#裡很好用! 您看完每個用法, 最好也給他多點練習!

看看谭浩强的C++那本书，不错。推荐给你
