C#基础-面向对象/static/this
C#基础-面向对象
基本跟java一样,区别:
1.内部成员,包内可见用:internal
2.派生类(继承):class Class2:Class1{}
3.总结this与static的用法
Sample of static
1 using System;
2
3 class Employee
4 {
5 public static decimal salary;//static member
6 public string name;//non-static member
7 public static void setSalary(decimal B)//static method
8 {
9 salary = B;//right,equivalence declaration:Employee.Salary = B;
10 }
11 public void setName(string N)//non-static memeber
12 {
13 name = N;//right,equivalence declaration:this.name = N;
14 }
15 }
16
17 public class Sample
18 {
19 public static void Main()
20 {
21 Employee.salary = 8000.0m;//right,static member can access through name of class
22 Employee.setSalary(8000.0m);//right,static method can access through name of class
23 Employee e = new Employee();
24 e.name = "Einstein"; //right, non-static memeber must access through the instance of class
25 e.setName("Einstein");//right,non-static method must access through the instence of class
26 Console.WriteLine("name of stuff is:{0}\nstuff salary:{1}",e.name,Employee.salary);
27 }
28 }
