What are the attributes in C#?

How does the decorator pattern work?

The decorator design pattern is a structural pattern, which provides a wrapper to the existing class. Decorator design pattern uses abstract classes or interfaces with the composition to implement the wrapper.
Which pattern is used when subclassing is not possible or impractical to add functionality at runtime in C#?

Basically, by using the decorator pattern you can add any number of additional responsibility to object at RUNTIME which you can not achieve by subclassing without potentially damaging your code structure or adding many duplicate combinations for subclasses.

In short, this decorator design pattern adds additional functionalities to the object by wrapping it. A decorator is an object that adds features to another object.
