人名币转大写

 public static string get(string num)
        {
            //129
            string chNum = "零壹贰叁肆伍陆柒捌玖";//定义好大写的数字

            string zheng = "元拾佰仟万拾佰仟亿拾佰仟万";//定义好数位,从小到大排  


            string xiaoshu = "角分";//把整数和小数分开处理  
            string result = string.Empty;

            if (num.Contains("."))
            {
                string[] temp = num.Split('.');
                int index = temp[0].Length - 1;
                for (int i = 0; i < temp[0].Length; i++)
                {
                    result += chNum[Convert.ToInt32(temp[0][i].ToString())];
                    result += zheng[index];
                    index--;
                }
                for (int i = 0; i < temp[1].Length; i++)
                {
                    //89
                    result += chNum[Convert.ToInt32(temp[1][i].ToString())];
                    result += xiaoshu[i];
                }
            }
            else
            {
                int index = num.Length - 1;
                for (int i = 0; i < num.Length; i++)
                {
                    result += chNum[Convert.ToInt32(num[i].ToString())];
                    result += zheng[index];
                    index--;
                }
            }
            return result;
        }

调用  string result = get("129.98");
