How to Use LINQ in C# – Practical Examples for .NET Developers

Описание: Small data transformations are everywhere in everyday development.

From filtering collections to generating quick reports, most C# developers still rely on manual loops more than they should.

LINQ changes that.

In this video, I explain what LINQ is, why it was introduced, and how it fundamentally changes the way you work with data in C#.

No unnecessary theory. Just practical reasoning and real code examples.

We start from the traditional foreach approach and then progressively move to LINQ, understanding:
What IEnumerable really means
Why deferred execution matters
The difference between method syntax and query syntax
The core operators you’ll use 80% of the time

Using a simple console application, I show how to:
Filter data with Where
Transform data with Select
Sort results with OrderByDescending
Retrieve elements safely with FirstOrDefault
Validate conditions using Any
Produce summaries with Count

All inside a clean and runnable example.

🧠 What You’ll Learn
What LINQ is and why it was created
How LINQ works under the hood with IEnumerable
What deferred execution really means
The most important LINQ operators for real-world .NET code
How to structure readable and maintainable queries
