C# Tip: Relational Patterns Matching

Relational Patterns Matching, introduced in C# 9, enhances the way you can match values to patterns in a concise and expressive manner. This functional programming technique focuses on evaluating expressions rather than controlling the flow of your code.

✅ Advantages of Relational Patterns Matching:

• Conciseness: It simplifies your code, making it shorter and more readable.
• Expressiveness: It allows you to express complex conditions cleanly and intuitively.

🔥 Example: Categorizing Age using Relational Patterns Matching

Here’s how you can use relational patterns to categorize a person’s age:

💡 Key Points:

• Concise Code: The switch expression simplifies branching logic and avoids long if-else chains.
• Readable: The logic is more intuitive, making it easier to understand and maintain.
• Expressive Conditions: The and keyword allows you to chain multiple relational operators together.

🤔 Which pattern matching technique do you prefer for your scenarios?
