Problem

I've just had to write a string reverse function in C# 2.0 (i.e. LINQ not available) and came up with this:

public string Reverse(string text)
{
    char[] cArray = text.ToCharArray();
    string reverse = String.Empty;
    for (int i = cArray.Length - 1; i > -1; i--)
    {
        reverse += cArray[i];
    }
    return reverse;
}

Personally I'm not crazy about the function and am convinced that there's a better way to do it. Is there?

Solution

public static string Reverse( string s )
{
    char[] charArray = s.ToCharArray();
    Array.Reverse(charArray);
    return new string(charArray);
}

Code Snippets

public static string Reverse( string s )
{
    char[] charArray = s.ToCharArray();
    Array.Reverse(charArray);
    return new string(charArray);
}
