How to: Inherit from a Class

This example defines the Circle and Rectangle classes, which both inherit from the Shape class, and the Square class, which inherits from the Rectangle class.

Example

public class Shape
{
    // Definitions of properties, methods, fields, and events.
}
public class Circle : Shape
{
    // Specialized properties, methods, fields, events for Circle.
}
public class Rectangle : Shape
{
    // Specialized properties, methods, fields, events for Rectangle.
}
public class Square : Rectangle
{
    // Specialized properties, methods, fields, events for Square.
}

Compiling the Code

• Create a new console application.

• Copy the code and paste it right before or after the Program class declaration.

Robust Programming

Make sure the class you want to inherit is not sealed.
