Open Close Principle with C#
Open Close Principle is an Object Oriented Design principle. It is first introduced by Betrand Meyer in 1988. He says “Software entities (Class, module, function etc.) should be open for extension, but closed for modification”. An entity is “Open for extension” means that its behavior can be extended to accommodate new demand. The entity is
Singleton Design Pattern with C#
Design Pattern Design pattern is a solution of known problems. These are strategies of solving commonly occurring problems. A design pattern is not a finish design. It is like a template to solve a problem. Singleton Design Pattern Singleton is a software design pattern. It is restrict to create object more than once. This is

Iterator Design Pattern with C#
Iterator pattern is a design pattern which is used to traverse aggregate object often called container and access container’s object without exposing it’s underlying representation. Iterator pattern decoupled algorithm from aggregate object or container. In some cases, algorithms are container specific.

Strategy Design Pattern with C#
Strategy design pattern is a behavioral design pattern. It is a particular software design pattern where algorithms are selected at runtime. According to the book of Design Pattern (Gang of Four) – “Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.
