This program demonstrates how to define and use an interface in C#. An interface is a set of related properties and methods that a class or struct can implement. In this case, the interface IValue has two properties: Count and Name.
The Image and Article classes both implement the IValue interface, meaning that they must provide their own implementation for each of the properties and methods defined in the interface.
You can see that the Image class has a straightforward implementation of the Name property, while the Article class converts the value of the Name property to uppercase when it is set.
The Main method creates two objects, value1 and value2, that implement the IValue interface. It then increments the Count property of each object and sets the Name property of each object to a different string. Finally, it prints the value of the Name property for each object to the console.
