Public vs private access : Public : Class C# Examples

It is OK for a member of a class to access a private member of the same class.




    
using  System;  
  
class  MyClass  {    
    private  int  a;  //  private  access  explicitly  specified  
    int  b;                    //  private  access  by  default  
    public  int  gamma;    //  public  access  
      
    public  void  setAlpha(int  val)  {  
        a  =  val;    
    }  
  
    public  int  getAlpha()  {  
        return  a;  
    }  
  
    public  void  setBeta(int  a)  {  
        b  =  a;    
    }  
  
    public  int  getBeta()  {  
        return  b;  
    }  
}    
    
class  AccessDemo  {    
    public  static  void  Main()  {    
        MyClass  ob  =  new  MyClass();    
    
        /*  Access  to  a  and  b  is  allowed  only  through  methods.  */  
        ob.setAlpha(-99);  
        ob.setBeta(19);  
        Console.WriteLine("ob.a  is  "  +  ob.getAlpha());  
        Console.WriteLine("ob.b  is  "  +  ob.getBeta());  
  
        //  You  cannot  access  a  or  b  like  this:  
//    ob.a  =  10;  //  Wrong!  a  is  private!  
//    ob.b  =  9;      //  Wrong!  b  is  private!  
  
        //  It  is  OK  to  directly  access  gamma  because  it  is  public.  
        ob.gamma  =  99;    
      }    
}
