• Static and Singleton Classes in C#Sep 23, 2023. Object-Oriented Programming (OOP) in C# is a way to organize code neatly. There are two types of classes: static and singleton. Static classes have functions that you can use without creating an object. They're great for simple tasks, but can cause issues if used too much. Singleton classes ensure there's only one instance of a class. They're useful for managing shared resources. Both have pros and cons. Static classes are simple and fast, but may create problems with too much shared data. Singleton classes are good for controlling resources but are more complex. Choose the one that fits your project's needs.

Object oriented programming is the backbone of software development these days and this holds for C# development as well. Design Patterns: Elements of Reusable Object-Oriented Software (1994) is a software engineering book which describes software design patterns. The book was written by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, with a foreword by Grady Booch. It describes 23 classic software design patterns and is regarded as an important source for object-oriented design theory and practice. The authors are often referred to as the Gang of Four (GoF). This book includes examples in C++ and Smalltalk. These design patterns have been divided into three categories and in this article, I will provide two samples from each category in C#.
