How to Use Reverse String in C#: Using Array, For Loop & Reverse

Explore multiple ways to reverse a string in C#, including using Array.Reverse, a for loop, and built-in methods, with practical code examples.

Why Reverse a String?

Reversing a string is a common interview question and practical exercise that helps you understand how strings, arrays, and character manipulation work in C#.

Using Array.Reverse

One of the simplest approaches is converting the string to a character array using ToCharArray(), reversing it with Array.Reverse(), and then reconstructing the string with the new string() constructor.

Using a For Loop

A manual approach involves looping through the string from the last character to the first, appending each character to a new string or StringBuilder, giving you full control over the process.

Using Built-in LINQ Methods

C# also allows reversing a string concisely using LINQ's Reverse() method combined with string.Concat(), offering a compact, readable one-line solution for experienced developers.
