目前試用了個還沒有發現什麼問題，感覺還行吧，所以發來供大家參考
1. 引用命名空間：using System.Text.RegularExpressions;(操作正則表達式)
2. 小寫轉大寫
public static string sToh(string ch)
{
string str = ""; switch(ch)
{
case "1": str = "壹"; break; case "2": str = "貳"; break; case "3": str = "參"; break; case "4": str = "肆"; break; case "5": str = "伍"; break; case "6": str = "陸"; break; case "7": str = "柒"; break; case "8": str = "捌"; break; case "9": str = "玖"; break; default: str = "零"; break;
} return str;
}3. 獲得數位位數
private static string getBit(int ilen) { string str = ""; switch(ilen) { case 2: str = "拾"; break; case 3: str = "佰"; break; case 4: str = "仟"; break; case 5: str = "萬"; break; case 6: str = "拾"; break; case 7: str = "佰"; break; case 8: str = "仟"; break; case 9: str = "億"; break; case 10: str = "拾"; break; case 11: str = "佰"; break; case 12: str = "仟"; break; case 13: str = "兆"; break; case 14: str = "拾"; break; case 15: str = "佰"; break; case 16: str = "仟"; break; default: str = ""; break; }4. 轉換

7 if( money.IndexOf(".")>0)

23 for(int i=0; i<strTemp.Length; i++)
24 {

27 }

30 {
31 strDecimal += sToh(Decimal.Substring(i,1));
32 }

34 strValue = regex.Replace(strValue,"零");
