This pattern is designed so that multiple decorators can be stacked on top of each other, each time adding a new functionality to the overridden method(s). Note that decorators and the original class object share a common set of features. In the previous diagram, the operation() method was available in both the decorated and undecorated versions.
In software engineering, the adapter pattern is a software design pattern (also known as wrapper, an alternative naming shared with the decorator pattern) that allows the interface of an existing class to be used as another interface. [1] It is often used to make existing classes work with others without modifying their source code.
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
A class diagram exemplifying the singleton pattern. In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. It is one of the well-known "Gang of Four" design patterns, which describe how to solve recurring problems in object-oriented software. [1]
In software engineering, the multiton pattern is a design pattern which generalizes the singleton pattern. Whereas the singleton allows only one instance of a class to be created, the multiton pattern allows for the controlled creation of multiple instances, which it manages through the use of a map .
factory method pattern, which allows a class to defer instantiation to subclasses. [4] prototype pattern, which specifies the kind of object to create using a prototypical instance, and creates new objects by cloning this prototype. singleton pattern, which ensures that a class only has one instance, and provides a global point of access to it.

More than 4.4 million voters have cast early ballots in North Carolina, 4.2 million of them in person, according to the lab. The North Carolina Board of Elections said the number of early voters ...
The builder pattern is a design pattern that provides a flexible solution to various object creation problems in object-oriented programming.The builder pattern separates the construction of a complex object from its representation.
