Since you explicitly defined the foo constructor to require int int now you. However if you manually create new constructor with parameter and delete the default constructor C will assume that your class can now create new object by itself and. The order in which class constructors that form a hierarchy are called.

Load the assembly up using the IL disassembler and have a look. Try to use Factory pattern. I dont think youre going to be able to inherit from the class you want as its constructors are private.

Inheritance together with encapsulation and polymorphism is one of the three primary characteristics of object-oriented programming. I could be wrong but I believe since you are inheriting from foo you have to call a base constructor. The inheritance mechanism allows the child class to access the parent members except its private members as if it is the members owner.

Although with interfaces multiple inheritance is supported by C. This is because C does not support multiple inheritance with classes. The class from which a new class is created is known as.

In the other hand if you implement a constructor with parameters and no paramterless constructor your class wont be instantiable without arguments. In C it is possible to inherit fields and methods from one class to another. It is a key feature of Object-Oriented Programming OOP.
