Convert String To camelCase from TitleCase C#

Question

I have a string that I converted to a TextInfo.ToTitleCase and removed the underscores and joined the string together. Now I need to change the first and only the first charact

Answer 1

Here is my code, in case it is useful to anyone

    // This converts to camel case
    // Location_ID => LocationId, and testLEFTSide => TestLeftSide

    static string CamelCase(string s)
    {
        var x = s.Replace("_", "");
        if (x.Length == 0) return "Null";
        x = Regex.Replace(x, "([A-Z])([A-Z]+)($|[A-Z])",
            m => m.Groups[1].Value + m.Groups[2].Value.ToLower() + m.Groups[3].Value);
        return char.ToUpper(x[0]) + x.Substring(1);
    }

The last line changes first char to uppercase, but you can change to lowercase, or whatever you like.
