c#实现小写金额转换成大写金额

最近在开发新农合mis系统，打印时用到了大写金额，整理了网上一些资料，写了个函数供有需要的参考：

 

private string ConvertToCh(decimal vpdMoney,ref string vpsCnMoney)
        {
            string sCnDigit = "零壹贰叁肆伍陆柒捌玖";            //0-9所对应的汉字
            string sCnUnit = "万仟佰拾亿仟佰拾万仟佰拾元角分"; //数字位所对应的汉字
            string sTemp1 = "", sTemp2 = "";
            int i,j;
            string sCn1 = "";//数字的汉语读法
            string sCn2 = "";//数字位的汉字读法
            int iTemp, iZero = 0;//用来计算连续的零值是几个

            //将要转换的金额取绝对值并四舍五入取2位小数
            vpdMoney = Math.Round(Math.Abs(vpdMoney), 2);
            //将要转换的金额乘100并转换成字符串形式
            sTemp2 = ((long)(vpdMoney * 100)).ToString();
            //判断是否溢出
            j = sTemp2.Length;
            if(j > 15)
            {
                return "溢出";
            }
            //取出对应位数的汉字位置。如：199.01,j为5所以:佰拾元角分
            sCnUnit  = sCnUnit.Substring(15 - j);

            //循环取出每一位转换成相应的值
            for (i = 0; i < j; i++)
            {
                sTemp1 = sTemp2.Substring(i, 1);//取出需转换的某一位的值
                iTemp = Convert.ToInt32(sTemp1);//转换为数字
               
                if (i != (j - 3) && i != (j - 7) && i != (j - 11) && i != (j - 15))
                {
                    //当所取位数不为元、万、亿、万亿上的数字时
                    if (sTemp1 == "0")
                    {
                        sCn1 = "";
                        sCn2 = "";
                        iZero = iZero + 1;
                    }
                    else
                    {
                        if (sTemp1 != "0" && iZero != 0)
                        {
                            sCn1 = "零" + sCnDigit.Substring(iTemp * 1, 1);
                            sCn2 = sCnUnit.Substring(i, 1);
                            iZero = 0;
                        }
                        else
                        {
                            sCn1 = sCnDigit.Substring(iTemp * 1, 1);
                            sCn2 = sCnUnit.Substring(i, 1);
                            iZero = 0;
                        }
                    }
                }
                else
                {
                    //该位是万亿，亿，万，元位等关键位
                    if (sTemp1 != "0" && iZero != 0)
                    {
                        sCn1 = "零" + sCnDigit.Substring(iTemp * 1, 1);
                        sCn2 = sCnUnit.Substring(i, 1);
                        iZero = 0;
                    }
                    else
                    {
                        if (sTemp1 != "0" && iZero == 0)
                        {
                            sCn1 = sCnDigit.Substring(iTemp * 1, 1);
                            sCn2 = sCnUnit.Substring(i, 1);
                            iZero = 0;
                        }
                        else
                        {
                            if (sTemp1 == "0" && iZero >= 3)
                            {
                                sCn1 = "";
                                sCn2 = "";
                                iZero++;
                            }
                            else
                            {
                                if (j >= 11)
                                {
                                    sCn1 = "";
                                    iZero++;
                                }
                                else
                                {
                                    sCn1 = "";
                                    sCn2 = sCnUnit.Substring(i, 1);
                                    iZero++;
                                }
                            }
                        }
                    }
                }
                if (i == (j - 11) || i == (j - 3))
                {
                    //如果该位是亿位或元位，则必须写上
                    sCn2 = sCnUnit.Substring(i, 1);
                }
                vpsCnMoney = vpsCnMoney + sCn1 + sCn2;

                if (i == j - 1 && sTemp1 == "0")
                {
                    //最后一位（分）为0时，加上“整”
                    vpsCnMoney = vpsCnMoney + '整';
                }
            }
            if (vpdMoney == 0)
            {
                vpsCnMoney = "零元整";
            }
           
            return "";
        }

小知识：

据说为了杜绝当时的财务混乱现状，朱元璋总结经验教训，在财务管理上进行技术防范，实施了一系列新的管理措施，其中一条就是将汉字中的数字“一、二、三、四、五、六、七、八、九、十、百、千”，在进行的钱粮等财务登记时改写为“壹、贰、叁、肆、伍、陆、柒、捌、玖、拾、陌、阡”。这一举措成为中国历史上金额大写字的首创。随着社会的发展，后来“陌、阡”慢慢演变成了“佰、仟”，沿用至今。
