Object Oriented Programming

see the code below

public class ClassA
   {
       public void MethodA()
       {
           Console.WriteLine("Class A Method Called");
       }

   }

   public class ClassB : ClassA
   {
       public void MethodB()
       {
           Console.WriteLine("Class B Method Called");
       }

   }

Now if i've created object of ClassB as

ClassB objClassB = new ClassB();

and i want to access the method of classA through this objClassB object

(want to access MethodA() with objClassB )

How i can do it without creating instance of ClassA
