Design Patterns in C#: Visitor

Learn everything there is to know about the Visitor Design Pattern

The Visitor Design Pattern is an advanced design pattern in software engineering, commonly used to separate algorithms from the objects they operate on, enabling new operations to be added without modifying the object structure. This pattern is essential for developers, as it promotes flexibility and extendibility in complex systems with structured data elements. The Visitor pattern is particularly useful in applications dealing with composite objects, such as abstract syntax trees, data analysis frameworks, or file systems. In this course, Amichai Mantinband will guide you through everything you need to understand and implement the Visitor pattern, empowering you to build extensible, maintainable, and adaptable applications.
