面向对象之封装

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

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
student s = new student();//初始化对象

//s.Code = 1;
s.Name = "zhangsan";//Code,Name是类的成员

s.shuzi = 19;
Console.Write(s.Code.ToString());

Console.ReadLine();
}
}
}

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

namespace ConsoleApplication1
{
class student
{
private int _Code;//private只能在自己的类中访问

public int Code//封装属性
{//有两个方法
get { return shuzi; }//1.读
set {
if (value >= 1 && value <= 10)
_Code = value;
else
_Code = 0;
}//2.取
}

public int shuzi;

public string Name;//public可以再其他类中访问

}
}
