accessing non-static method from another class without instantiate

KALEEM says:

public void B1()

       {

           Console.WriteLine("I am from Class B");

       }

 Hi,

Make this method Static.then you can access by Class name without instantiating Class.i.e

B.B1();

I hope this will help you out.

I said to interviewer for static keyword 

then he refused  and said call it without using static 

Hi,

You need to inherit Class A to B ,and then simply you can call B1 by using Class A obj.

class A : B

and by using below code.

A a = new A();
a.A1();
a.B1();

I hope this will help you out.

Without using Inheritance

@Kaleem, this is the way to do this

 class A 
        {
            public void A1()
            {
                Console.WriteLine("I am from Class A");
            }
        }
          class B
        {
           public static void B1()
            {
                Console.WriteLine("I am from Class B");
            }
        }
       static class Program 
        {
            
            static void Main(string[] args)
            {
                // I call Class A object then call his method..
                A a = new A();
                a.A1();
                
                //  Call B1 Method without creating class B object ???????
                B.B1();
            }
        }

 Inheritance

  class A : B
        {
            public void A1()
            {
                Console.WriteLine("I am from Class A");
            }
        }
        class B
        {
            public static void B1()
            {
                Console.WriteLine("I am from Class B");
            }
        }
        static class Program
        {

              void Main(string[] args)
            {
                // I call Class A object then call his method..
                A a = new A();
                a.A1();

                //  Call B1 Method without creating class B object ???????
                B.B1();
            }
        }
