How to Check if a String is a Palindrome in C#
Have you ever needed to check if a string is a palindrome in your C# code? A palindrome is a word, phrase, number, or other sequence of characters that reads the same forward and backward. For example, "racecar" is a palindrome. In this blog post, I'll show you how to write a C# extension method to check if a string is a palindrome. An extension method is a special kind of static method that allows you to add new methods to existing types without modifying the original type. Here's the code snippet for the IsPalindrome extension method: public static bool IsPalindrome(this string input) { string normalized = input.ToLower(); int length = normalized.Length; for (int i = 0; i < length / 2; i++) { if (normalized[i] != normalized[length-1-i]) { return false; } } return true; } Let's break down how this method works. First, we create a normalized copy of the input string by converting it to lowercase. This allows u
