unity第二周：关于属性

一.

using System;
//属性，property
//可以在类，结构体，接口中
//属性本质是方法
//field：域，字段
//属性：不确定存储位置。set,get,访问器
namespace _013_属性
{
public class A
{
private int num;
public int Age
{
get { return num; }
set
{
num = value;//这个value的意思是外面传进来的值
}
}
public int Myage { get; set; }//两种等价，都是属性，简写更好
}
public class Student
{
private string code = "coder";
private string name = "name";
private int age;
public string Code
{
get
{
return code;
}
set
{
code = value;
}
}
public string Name
{
get { return name; }
set { name = value; }
}
public int Age
{
get { return age; }
set { age = value; }
}
public override string ToString()
{
return "Code = "+Code+" ,Name = "+Name+" ,age= "+Age;
}
}
class Program
{
static void Main(string[] args)
{
Student student = new Student();
student.Age = 21;
student.Name = "约翰.马可";
student.Code = "ProjectOne";
Console.WriteLine("StudentInfo: "+student.ToString());
}
}
}

二.

using System;

namespace _014_抽象属性
{
public abstract class Person
{

public abstract string Name
{
get;
set;
}
//快速敲出属性：prop+ tab键
public abstract int Age { get; set; }//这里实际上是没有实现的，只是因为是语法糖，看起来像实现的
//抽象属性不能像下面这么写，因为抽象说明不能实现，下面这么写实际上就是实现了
// private int age;
// public abstract int Age {
// get
// {
// return age;
// };
// set
// {
// age = value;
// };
// }
//
}
public class Student : Person
{
private string code = "code";
private string name = "name";
private int age = 0;
public override string Name
{
//lamda表达式，暂不解释
// get => throw new NotImplementedException();
// set => throw new NotImplementedException();
get
{
return name;
}
set
{
name = value;
}
}
public override int Age
{
// get => throw new NotImplementedException();
// set => throw new NotImplementedException();
get
{
return age;
}
set
{
age = value;
}
}
public string Code { get; set; }

public override string ToString()
{
return "Code = " + Code + " ,Name = " + Name + " ,age= " + Age;
}
}
class Program
{
static void Main(string[] args)
{
Student student = new Student();
student.Age = 10;
student.Name = "约翰.马可";
student.Code = "ProjectOne";
student.Age++;
Console.WriteLine("StudentInfo: " + student.ToString());
}
}
}
