Reverse of a string without using the Reverse function in C# and VB

Another way,

public static class ReverseStringExtension
{
    public static string Reverse(this string dataToRevese)
    {
        Func<string, string> reverseFunc = (dataToFunc) =>
        {
            StringBuilder reverseBuilder = new StringBuilder();
            for (int index = 0; index < dataToFunc.Length; )
                reverseBuilder.Append(dataToFunc[dataToFunc.Length - ++index]);
            return reverseBuilder.ToString();
        };

        return string.IsNullOrEmpty(dataToRevese) ? default(string) : reverseFunc(dataToRevese);
    }
}

Usage:

string stringRequireReverse = "Hello world, I am going to be reversed.";
stringRequireReverse = stringRequireReverse.Reverse();
