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

public static string CamelCase(this string str)  
    {  
      TextInfo cultInfo = new CultureInfo("en-US", false).TextInfo;
      str = cultInfo.ToTitleCase(str);
      str = str.Replace(" ", "");
      return str;
    }

This should work using System.Globalization
