What you'll learn

Real-world apps almost always require manipulating entire sets of data – not just individual objects. In C# apps, that data is stored in collections. In this course, C# 14 Collections and LINQ, you’ll gain the ability to write effective code that handles collections of data. First, you’ll explore how to put multiple objects into collections, so you can look up particular items of data or enumerate through an entire collection. Next, you’ll discover how to choose which collection – for example, a list, a dictionary, or a hashset - is most suited to your needs. Finally, you’ll learn how to run sophisticated in-memory queries on your collections to retrieve specific data using LINQ. When you’re finished with this course, you’ll have the skills and knowledge of collections and LINQ needed to write apps that process large amounts of data.
