第一种方法：
用正则表达式，C#方法如下
usingSystem.Text.RegularExpressions;//首先引入命名空间
private string DaXie ( string money )
{
string s = double . Parse ( money ). ToString ( "#L#E#D#C#K#E#D#C#J#E#D#C#I#E#D#C#H#E#D#C#G#E#D#C#F#E#D#C#.0B0A" );
string d = Regex . Replace ( s , @ "((?<=-|^)[^1-9]*)|((?'z'0)[0A-E]*((?=[1-9])|(?'-z'(?=[F-L\.]|$))))|((?'b'[F-L])(?'z'0)[0A-L]*((?=[1-9])|(?'-z'(?=[\.]|$))))" , "${b}${z}" );
return Regex . Replace ( d , "." , delegate ( Match m ) { return "负圆空零壹贰叁肆伍陆柒捌玖空空空空空空空分角拾佰仟万億兆京垓秭穰" [ m . Value [ 0 ] - '-' ]. ToString (); });
}
第二种方法：
采用数组，C#方法如下
private string DaXie ( string money )
{
//将小写金额转换成大写金额
double MyNumber = Convert . ToDouble ( money );
String [] MyScale = { "分" , "角" , "元" , "拾" , "佰" , "仟" , "万" , "拾" , "佰" , "仟" , "亿" , "拾" , "佰" , "仟" , "兆" , "拾" , "佰" , "仟" };
String [] MyBase = { "零" , "壹" , "贰" , "叁" , "肆" , "伍" , "陆" , "柒" , "捌" , "玖" };
String M = "" ;
bool isPoint = false ;
if ( money . IndexOf ( "." ) != - 1 )
{
money = money . Remove ( money . IndexOf ( "." ), 1 );
isPoint = true ;
}
for ( int i = money . Length ; i > 0 ; i --)
{
int MyData = Convert . ToInt16 ( money [ money . Length - i ]. ToString ()); //?
M += MyBase [ MyData ]; //?
if ( isPoint == true )
{
M += MyScale [ i - 1 ]; //?
}
else
{
M += MyScale [ i + 1 ]; //?
}
}
return M ;
