大写金额转换成小写

Q:如何将大写金额转换成小写？

A:简单点，格式比较严格

private   float  getMoney( string  strBig)
         ... {
             string  strExp = "" ;
             string [] arrBig   =   new   string []  ... {  " 整 " , "" , " 零 " , " +0 " , " 壹 " , " +1 " , " 贰 " , " +2 " , " 叁 " , " +3 " , " 肆 " , " +4 " , " 伍 " , " +5 " , " 陆 " , " +6 " , " 柒 " , " +7 " , " 捌 " , " +8 " , " 玖 " , " +9 " ,  " 分 " , " *0.01 " , " 角 " , " *0.1 " , " 元 " , " *1 " , " 拾 " , " *10.00 " , " 佰 " , " *100.00 " , " 仟 " , " *1000.00 " , " 万 " , " *10000.00 " , " 亿 " , " *100000000.00 " } ;
             for  ( int  i  =   0 ; i  <  strBig.Length; i ++ )
             ... {
                 for  ( int  j  =   0 ; j  <  arrBig.Length - 1 ;j += 2  )
                 ... {
                     if  (arrBig[j]  ==  strBig[i].ToString())
                     ... {
                        strExp  +=  arrBig[j  +   1 ].ToString();
                         continue ;
                    }
                }
            }

             object   ret = new  DataTable().Compute(strExp,  "" );
             return   float .Parse(ret.ToString());
             // Console.WriteLine(getMoney("玖仟零贰拾壹元陆角肆分"));
             // Console.WriteLine(getMoney("玖仟万亿零贰拾壹元陆角肆分"));
        }

 伴水兄的这个较狠
