Text.ToUpper() Question

Use following

  static string DoFormatting(string strValue)
        {
            if (!strValue.Contains("_"))
            {
                return strValue.ToUpper();
            }
            var splitValues = strValue.Split('_');
            string returnValue = splitValues[0].ToUpper();
            return string.Concat(returnValue, "_", splitValues[1].Substring(0, 1).ToUpper(),
                splitValues[1].Substring(1, splitValues[1].Length - 1));
        }
