Getting Started With LINQ in C#

Requirements

Collections are everywhere. Comments in a post, purchased items in an invoice, and guests in a hotel reservation.

We often work with these collections using for, foreach, and other loops. But C#, has a feature specifically designed for working with collections:

Language Integrated Query (LINQ).

With LINQ, you filter, transform, and query collections, using more concise and readable code than traditional loops.

This is the one C# feature you can’t ignore. In fact, it’s the best of all C# features. Ever.

 

What you will learn?

In this course, we’re covering everything you need to know to start working productively with LINQ, in less than 2 hours.

After taking this course, you will:

  • Understand the key differences between LINQ and loops.
  • Learn the most frequently used LINQ methods for working with collections.
  • Identify and fix common mistakes when using LINQ.
  • Refactor away from conditionals using LINQ.
  • Explore the latest LINQ methods and overloads from recent .NET versions.

LINQ works with XML files and database records too. But, in this course, we’re focusing on LINQ and collections like arrays and lists.

Think of this course like the 20% of the LINQ features you’re using 80% of the time (That’s the Pareto Principle, by the way). We’re not covering every single LINQ method out there, but the most frequently used ones. And that’s on purpose. In our every day coding (and jobs) we keep using a handful of methods most of the time.

 

Who is this course for?

If you’re a beginner or intermediate C# developer who want to write more compact and expressive code when working with collections, this course is for you.

You should be comfortable declaring and initializing C# objects and working with conditionals, loops, and collections such as arrays and lists.

By the end of this course, you’ll be ready to productively manipulate collections with LINQ.

See you in the first lesson.
