C# ----- class
C#是一种面向对象编程的语言,所以类的运用是非常实用的。class的使用与c++基本一样,下面可以看一下C#对于class类的使用例程
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 namespace ConsoleApplication1 8 { 9 class student 10 { 11 private int age=5; 12 public int Age 13 { 14 get{return age;} 15 set { if (value >= 0) age = value; } 16 } 17 } 18 class rectangle 19 { 20 double length, width; 21 public void create(double x,double y) 22 { 23 length = x; 24 width = y; 25 } 26 public double getArea() 27 { 28 return (length * width); 29 } 30 public void show() 31 { 32 Console.WriteLine("Length={0},width={1},Area={2}",length,width,getArea()); 33 } 34 } 35 class Program 36 { 37 static void Main(string[] args) 38 { 39 student s=new student(); 40 s.Age = 63; 41 Console.WriteLine("age={0}", s.Age); 42 rectangle r1=new rectangle(); 43 r1.create(12.5, 8.2); 44 r1.getArea(); 45 r1.show(); 46 Console.ReadKey(); 47 } 48 } 49 }
运行结果:
age=63
Length=12.5,width=8.2,Area=102.5
End. 谢谢!
