替换数字金额为大写金额

引用：string money=ConvertMoney(TextBox1.Text.Trim());

支持12位数字：

需要定义的数组
        //定义数字转换
        private static string[] cstr={"零","壹","贰","叁","肆", "伍", "陆","柒","捌","玖"};
        //定义金额单位转换
        private  static string[] wstr={"","","拾","佰","仟","萬","拾","佰","仟","億","拾","佰","仟"};
        //定义金额单位转换
        private  static string[] wstrdot={"","分","角"};

 

替换的两个方法

        /// </summary>
        /// <param name="strMoney">接受用户输入的数字金额</param>
