Question

Can you reverse a string using String builder class?

Answer 1

Have you seen this?

https://www.techiedelight.com/reverse-string-csharp/

It shows a few ways of reversing a string in c# including one that uses StringBuilder to append each character in reverse order.

The following adapted version runs in Sololearn's Code Playground:
using System;
using System.Text;

namespace SoloLearn
{
public static class Extensions
{
public static string reverse(this string str)
{
StringBuilder sb = new StringBuilder();

for (int i = str.Length - 1; i >=0 ; i--)
{
sb.Append(str[i]);
}

return sb.ToString();
}
}

class Program
{
public static void Main()
{
string str = "Reverse Me!!";

string reverse = str.reverse();
Console.WriteLine(reverse);
}
}
}
