Concat and Union Operators in LINQ C# - Complete Guide

Learn how to use Concat and Union operators in LINQ to combine multiple collections effectively. Master the differences between these essential LINQ operators with practical C# examples.

In this comprehensive tutorial, we'll explore two powerful LINQ operators that allow you to merge data from multiple sources. Whether you're working with primitive types, custom objects, or handling null collections, this video covers all scenarios you need to know.

What you will learn:
• Understanding Concat operator and how it combines collections
• Understanding Union operator and duplicate element removal
• Practical differences between Concat and Union
• Working with primitive types (int, string)
• Handling null collections safely
• Case-insensitive string comparisons
• Working with custom types and objects
• Real-world examples and code implementations

We'll start by explaining the fundamental concepts of both operators, then move through multiple code examples demonstrating each scenario. The Concat operator combines two same-type collections while preserving duplicates, whereas Union removes duplicate elements automatically. By the end of this video, you'll have a solid foundation in using these operators to improve your data manipulation code.
