A Better Way to Write Complex Statements in C# Using Arrays

Are you struggling to write clean and efficient conditions in C# ? If you've ever found yourself tangled in a messy if statement to check multiple values, you're not alone. This common scenario can clutter your code and make it less readable, particularly when you're dealing with various conditions that require the same format.

In this guide, we'll break down a more elegant solution using arrays that not only improves readability but also enhances performance in your C# applications.

The Problem: Complex Conditions

Imagine you have an integer variable n, and you need to ensure that it doesn't equal a specific set of values — for example, 1, 4, and 11. Here's how you might traditionally write this condition:

While this solution works, it can quickly become unwieldy, especially as the number of conditions increases. Additionally, it’s not as readable, making it harder for future maintainers of the code, including yourself, to understand the logic at a glance.

The Solution: Using Arrays for Cleaner Checking

C# provides a straightforward way to simplify your conditions using arrays. By collecting all the values that need to be checked into an array, you can utilize built-in array functionality to make your code less verbose and more efficient. Here's how:

Step 1: Define the Forbidden Values in an Array

First, create an array that contains all the values that n should not equal:

Step 2: Use the Contains Method

Next, instead of multiple != checks, use the Contains method to easily determine if n is part of the forbidden array:

How This Improves Your Code

Simplification: Only one line is used to check if n is in the NotAllowed array, which greatly reduces complexity.

Increased Readability: This method makes it clear to anyone reading the code that you're checking against a set of values.

Easier Maintenance: If you need to add or remove values, you can simply modify the NotAllowed array without restructuring the entire logical statement.

Conclusion

By employing the use of arrays in C# , we can write cleaner, more maintainable code when handling complex conditions. This approach not only offers a prettier way of doing things but significantly enhances performance as well, especially in larger applications where readability and efficiency are paramount.

Next time you find yourself writing multiple conditional checks, consider refactoring your code using an array and the Contains method. Your future self (and your team members) will thank you!
