Multiple Inheritance

Rakesh reddy

HI all,

C# does't support multiple Inheritance - Reason is parent classes have the methods with the same name,

So while calling the parent class method from child class, the child class is getting confusion to which parent class related method to invoke.

Here my question is if i am the developer, then i will be take care for not to have the same methods names in Parent classes.

This time c# supports multiple inheritance please anyone explain the background reason why it is not supports multiple inheritance.

Thanking you in advance.

Rakesh you should use 2 interfaces to keep both parent class methods. So through those interface you can use your both parent class methods in child class. For future also this design will be helpful for you.

I will concentrate my answer to this specific question:

"why it is (C#) not supports multiple inheritance"

Simply, because it adds more complexity to the C# language while adds so less in terms of features, so the language designers decided not to permit it.

Moreover, I think it will violet the "SOLID" principle of single responsibility.

For more you can read here on MSDN:

Have you look into reflection? Here are a few examples.

HI Sujeet,

I have the Method1(), Method2() in calss named ParentA
and Method3(), Method4() in calss named ParentB
From different service providers.

I need to access the all member functions which are existed in both parent classes
in my child class. I need to use only one child class.

Hi Rakesh. If you do not want to using same method name, then what will be the benefit to allow two or more parents.
