how to use reference of a abstract class?

samrat matte

childclass obj=new childclass;
absparent p=obj;
p.test1();p.test2();p.test3();
where test1 and test 2 are methods of abstract class
while test 3 are methods of child class

@samrat,

You can't call test3 via an 'absparent' reference because it is a method of 'childclass' and the parent class doesn't therefore know anything about it.

However, you could call all 3 methods via a 'childclass' reference:

childclass obj = new childclass();
obj.test1();
obj.test2();
obj.test3();

mcn1 ob = new mcn1();
int result = ob.add(5, 10);
Console.WriteLine("the result is {0}", result);
}
}
