The following shows the basic code of the object pool design pattern implemented using C#. For brevity the properties of the classes are declared using C# 3.0 automatically implemented property syntax. These could be replaced with full property definitions for earlier versions of the language.
In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure that can be transplanted directly into source code. Rather, it is a description or a template for solving a particular type of ...

A rough chapter from The Principles, Patterns, and Practices of Agile Software Development, Robert C. Martin, Prentice Hall; Visitor pattern in UML and in LePUS3 (a Design Description Language)
A (software) design pattern is a general solution to a common problem in software design. It is a description or template for how to solve a problem, that can be used in different situations. A design pattern typically shows relationship and interaction between classes or objects, without specifying final application classes or objects that are ...
Ian Graham reviewed the first volume in the Journal of Object-Oriented Programming. [2] DBMS columnist David S. Linthicum found the first volume to be "the best book on patterns for application architects", while Bin Yang of JavaWorld thought it had "many interesting architecture and design patterns". [3] [4]
A design pattern is the re-usable form of a solution to a design problem. The idea was introduced by the architect Christopher Alexander [ 1 ] and has been adapted for various other disciplines, particularly software engineering .
The marker interface pattern is a design pattern in computer science, used with languages that provide run-time type information about objects.It provides a means to associate metadata with a class where the language does not have explicit support for such metadata.
In object-oriented programming, the iterator pattern is a design pattern in which an iterator is used to traverse a container and access the container's elements. The iterator pattern decouples algorithms from containers; in some cases, algorithms are necessarily container-specific and thus cannot be decoupled.
