C# Data Structures and Algorithms - Second Edition

By: Marcin Jamro

Overview of this book

Building your own applications is exciting but challenging, especially when tackling complex problems tied to advanced data structures and algorithms. This endeavor demands profound knowledge of the programming language as well as data structures and algorithms – precisely what this book offers to C# developers. Starting with an introduction to algorithms, this book gradually immerses you in the world of arrays, lists, stacks, queues, dictionaries, and sets. Real-world examples, enriched with code snippets and illustrations, provide a practical understanding of these concepts. You’ll also learn how to sort arrays using various algorithms, setting a solid foundation for your programming expertise. As you progress through the book, you’ll venture into more complex data structures – trees and graphs – and discover algorithms for tasks such as determining the shortest path in a graph before advancing to see various algorithms in action, such as solving Sudoku. By the end of the book, you’ll have learned how to use the C# language to build algorithmic components that are not only easy to understand and debug but also seamlessly applicable in various applications, spanning web and mobile platforms.

List-related interfaces

While developing applications in C#, you frequently use various collections, including lists. For this reason, it is worth mentioning three common interfaces:

  • IEnumerable
  • ICollection
  • IList

The order of them is important because IEnumerable is the base interface for ICollection and IList, while ICollection is the base interface for IList. However, what is inside such interfaces? Let’s take a look!

IEnumerable only provides you with a simple iteration over a collection. For this reason, it exposes the GetEnumerator method.

The ICollection interface adds the following methods for manipulating the collection:

  • Add adds a given item to the collection
  • Clear removes all the items from the collection
  • Contains checks whether a given item exists in the collection
  • Remove removes the first occurrence of a given item from the collection

It also exposes the Count and IsReadOnly properties, as well as the CopyTo...
