正则一则 将金额转换成人民币大写的代码

复制代码 代码如下:

public static string ConvertToChineseMoney(double money)
{
if (money < 0)
throw new ArgumentOutOfRangeException("参数money不能为负值！");
string s = 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");
s = 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(s, ".", delegate(Match m) { return "负元空零壹贰叁肆伍陆柒捌玖空空空空空空空分角拾佰仟萬億兆京垓秭穰"[m.Value[0] - '-'].ToString(); });
}

复制代码 代码如下:

Random r = new Random();
for (int i = 0; i < 10; i++)
{
double m = r.Next() / 100.0;
Response.Write(m + "---- " + ConvertToChineseMoney(m) + "<br/>");
}
