Demonstrate protected. : Protected : Class C# Examples

A protected member is public within a class hierarchy, but private outside that hierarchy.
A protected member is created by using the protected access modifier.





    
using  System;  
  
class  BaseClass  {  
    protected  int  i,  j;  //  private  to  BaseClass,  but  accessible  by  D  
  
    public  void  set(int  a,  int  b)  {  
        i  =  a;  
        j  =  b;  
    }  
  
    public  void  show()  {  
        Console.WriteLine(i  +  "  "  +  j);  
  }  
}  
  
class  DerivedClass  :  BaseClass  {  
    int  k;  //  private  
  
    //  DerivedClass  can  access  BaseClass's  i  and  j  
    public  void  setk()  {  
          k  =  i  *  j;  
    }  
  
    public  void  showk()  {  
        Console.WriteLine(k);  
    }  
}  
  
class  MainClass  {  
    public  static  void  Main()  {  
        DerivedClass  ob  =  new  DerivedClass();  
  
        ob.set(2,  3);  //  OK,  known  to  DerivedClass  
        ob.show();        //  OK,  known  to  DerivedClass  
  
        ob.setk();    //  OK,  part  of  DerivedClass  
        ob.showk();  //  OK,  part  of  DerivedClass  
    }
