《编程知识总结》15—c#中数字金额转换大写金额方法（Summary of programming knowledge 15 - c# in the amount of digital conversion of the amount of money method） The main function of the code is ConvertSum, and its parameter is a numeric string of type string. In ASP.NET, the following is called: Label1.Text=ConvertSum (string of numbers); The code is as follows: The main function of digital conversion / / / amount (including decimal) X Digital public string After the Chinese converted to uppercase x string or an error message string Public string ConvertSum (string STR) { If (... IsPositveDecimal (STR)) Return entered is not a positive number! ; If (Double.Parse (STR) 999999999999.99) Return the figures are too large to convert. Please enter the amount under $one trillion.; Char[] ch=new char[1]; Ch[0]=.; / / decimal point String[] splitstr=null; / / defined by an array of string segmentation after the decimal point Splitstr=str.Split (ch[0]); / / according to the decimal point string segmentation If (splitstr.Length==1) / / only integer part Return ConvertData (STR) + rounding; Else / / have a decimal portion { String rstr; Rstr=ConvertData (splitstr[0]) + circle; / / convert integer part Rstr+=ConvertXiaoShu (splitstr[1]); / / convert decimal part Return rstr; } } X To determine whether the digital string is always X Public string judgment Return true / / / if it is digital, and false otherwise. Public bool IsPositveDecimal (string STR) { Decimal d; Try { D=Decimal.Parse (STR); } Catch (Exception) { Return false; } If (d0) Return true; Else Return false; } X Public switched digital (integer) X Just need to convert a string of integer numbers Just after the capital is converted to a string of Chinese Public string ConvertData (string STR) { String tmpstr=; String rstr=; Int strlen=str.Length; If (strlen=4) / / digital length is less than four { Rstr= ConvertDigit (STR); } Else { If (strlen=8) / / digital length is greater than four, less than eight { Tmpstr=str.Substring (strlen-4,4); / / t
