Question

Since we know that constructor is not inherited in the child class as i asked in the my previous question Click here to view question

I had write the code

namespace TestConscoleApplication
{
    abstract public class A
    {
       public int c;
       public int d;

    private  A(int a, int b)
       {
           c = a;
           d = b;

       }
        public virtual void Display1()
        {
            Console.WriteLine("{0}{1}", c, d);
        }
    }
    internal class B : A 
    {
      protected  string Msg;

      public B(string Err)

        {
            Msg = Err;

        }

        public  void Display()
        {
            Console.WriteLine(Msg);
        }
    }



    class Program
    {
        static void Main(string[] args)
        {
            B ObjB = new B("Hello");


            Console.ReadLine();
        }
    }
}

when i compile the code its showing an error

Error TestConscoleApplication.A.A(int, int) is inaccessible due to its protection level.

Then why it is showing an error.

Answer 1

By making the only constructor of A private, you’ve prevented derived classes from being able to be constructed outside A.
