This article mainly explains "how to achieve multiple inheritance in C#". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "how to achieve multiple inheritance in C#".

C # multiple inheritance

Multiple inheritance refers to the function that a category can inherit behaviors and features from more than one parent class at the same time. In contrast to single inheritance, single inheritance means that a class can inherit from only one parent class.

C# does not support multiple inheritance. However, you can use interfaces to implement multiple inheritance. The following program demonstrates this:

Using System

Namespace InheritanceApplication

{

Class Shape

{

Public void setWidth (int w)

{

Width = w

}

Public void setHeight (int h)

{

Height = h

}

Protected int width

Protected int height

}

/ / Base class PaintCost

Public interface PaintCost

{

Int getCost (int area)

}

/ / derived class

Class Rectangle: Shape, PaintCost

{

Public int getArea ()

{

Return (width * height)

}

Public int getCost (int area)

{

Return area * 70

}

}

Class RectangleTester

{

Static void Main (string [] args)

{

Rectangle Rect = new Rectangle ()

Int area

Rect.setWidth (5)

Rect.setHeight (7)

Area = Rect.getArea ()

/ / print the area of the object

Console.WriteLine ("Total area: {0}", Rect.getArea ())

Console.WriteLine ("Total cost of paint: ${0}", Rect.getCost (area))

Console.ReadKey ()

}

}

}

When the above code is compiled and executed, it produces the following results:

Total area: 35 Total cost of paint: $2450 Thank you for your reading, this is the content of "how to achieve multiple inheritance of C#". After the study of this article, I believe you have a deeper understanding of how to achieve multiple inheritance of C#. The specific use of the situation also needs to be verified by practice.
