Example :

BaseClass

Derived class 1

    public class abcdef : xyz<IOrderView, Component1, Component2, Component3>

Derived class 2 public class rdesa : xyz

Class abcdef doesn't need 5 argument but class rdesa need to pass 5 argument . Can anyone tell me how to pass null as argument to base class . I'm new at this please help .

Answer 1

Long answer:

You need to re-examine your inheritance hierarchy after reading up on the Liskov substitution principle.

Short answer: You can pass some acceptable type to the base class constructor.

public class abcdef<IOrderView, Component1, Component2, Component3> 
    : xyz<IOrderView, Component1, Component2, Component3, object>
