Real-World Implementation of C# Design Patterns

Overview of this book

As a software developer, you need to learn new languages and simultaneously get familiarized with the programming paradigms and methods of leveraging patterns, as both a communications tool and an advantage when designing well-written, easy-to-maintain code. Design patterns, being a collection of best practices, provide the necessary wisdom to help you overcome common sets of challenges in object-oriented design and programming. This practical guide to design patterns helps C# developers put their programming knowledge to work. The book takes a hands-on approach to introducing patterns and anti-patterns, elaborating on 14 patterns along with their real-world implementations. Throughout the book, you'll understand the implementation of each pattern, as well as find out how to successfully implement those patterns in C# code within the context of a real-world project. By the end of this design patterns book, you’ll be able to recognize situations that tempt you to reinvent the wheel, and quickly avoid the time and cost associated with solving common and well-understood problems with battle-tested design patterns.

The Iterator pattern

Things were going well for Kitty as she worked on the control system, making liberal use of the Command pattern. Then, she hit something of a roadblock. Kitty’s command receiver logic was just taking bicycle orders from the customer ordering systems, such as direct sales, and the dealerships. The requests were processed in the order they were received. Due to this, Kitty and Phoebe noticed a slowdown. While the algorithms in AssemblyLineReceiver were optimized to efficiently produce bicycles, Kitty failed to consider the painting process.

The costliest part of the painting process in terms of time and money was setting everything up to paint a bicycle. This was very easy earlier when each bicycle was only allowed to be built in one color. Now, Bumble Bikes supports custom paint jobs. The sisters were losing time and money on custom jobs because the paint equipment had to be thoroughly cleaned and reset when a custom order was placed. The paint system...
