This problem cannot be solver easy. The question is Should it be solved? I think - no. I mean - if you are geting this string from outer source - e-mail txt file or something - you cannot garantee that your algorithm (any kind of it) will give correct result. What you will do in case of detected error? Will you ask again to resend this string to you? How? By e-mail or phone? What wil happens in case of undetected errors? To act (apply this getted number) according so long user input - this will allow to bad boys to make an injection.... if you are getting this string from same propram source - user input (textbox) and you want to be sure that user input is correct it will be better to replace this text box by number of comboboxes or numeric upDown controls and make something like this billinons thousand . And when user has finished this input simple collect the result from controls and ack him Do you really want to pay me twenty five billions dollar? :) String for asking you can generate by code that was showed to you above. :)

I dont know why you are not understanding my question............ In the first textbox  user enters a string like this : twenty five lac thirty seven thousand nine hundred and fifty.. So on button click He should get its equivalent number :  2537950............ Tell me the code for such application...........

Master Billa · Answer

HI You can use this code protected void Button1_Click(object sender EventArgs e) { txtWord.Text=ConvertNumberToWord(Convert.ToInt64(txtNumber.Text)); } private string ConvertNumberToWord(long nNumber) { long CurrentNumber = nNumber; string sReturn = ; if(CurrentNumber >= 1000000000) { sReturn = sReturn +   + GetWord(CurrentNumber/1000000000 Billion); CurrentNumber = CurrentNumber % 1000000000; } if(CurrentNumber >= 1000000) { sReturn = sReturn +   + GetWord(CurrentNumber/1000000 Million); CurrentNumber = CurrentNumber % 1000000; } if(CurrentNumber >= 1000) { sReturn = sReturn +   + GetWord(CurrentNumber/1000 Thousand); CurrentNumber = CurrentNumber % 1000; } if(CurrentNumber >= 100) { sReturn = sReturn +   + GetWord(CurrentNumber/100 Hundred); CurrentNumber = CurrentNumber % 100; } if(CurrentNumber >= 20) { sReturn = sReturn +   + GetWord(CurrentNumber ); CurrentNumber = CurrentNumber % 10; } else if(CurrentNumber > 0) { sReturn = sReturn +   + GetWord(CurrentNumber ); CurrentNumber = 0; } return sReturn.Replace(   ).Trim(); } private string GetWord(long nNumber string sPrefix) { long nCurrentNumber = nNumber; string sReturn = ; while(nCurrentNumber > 0) { if(nCurrentNumber > 100) { sReturn = sReturn +   + GetWord(nCurrentNumber / 100 Hundred); nCurrentNumber = nCurrentNumber % 100; } else if(nCurrentNumber > 20) { sReturn = sReturn +   + GetTwentyWord(nCurrentNumber / 10); nCurrentNumber = nCurrentNumber % 10; } else { sReturn = sReturn +   + GetLessThanTwentyWord(nCurrentNumber); nCurrentNumber = 0; } } sReturn = sReturn +   + sPrefix; return sReturn; } private string GetTwentyWord(long nNumber) { string sReturn = ; switch(nNumber) { case 2: sReturn = Twenty; break; case 3: sReturn = Thirty; break; case 4: sReturn = Forty; break; case 5: sReturn = Fifty; break; case 6: sReturn = Sixty; break; case 7: sReturn = Seventy; break; case 8: sReturn = Eighty; break; case 9: sReturn = Ninety; break; } return sReturn; } private string GetLessThanTwentyWord(long nNumber) { string sReturn = ; switch(nNumber) { case 1: sReturn = One; break; case 2: sReturn = Two; break; case 3: sReturn = Three; break; case 4: sReturn = Four; break; case 5: sReturn = Five; break; case 6: sReturn = Six; break; case 7: sReturn = Seven; break; case 8: sReturn = Eight; break; case 9: sReturn = Nine; break; case 10: sReturn = Ten; break; case 11: sReturn = Eleven; break; case 12: sReturn = Twelve; break; case 13: sReturn = Thirteen; break; case 14: sReturn = Forteen; break; case 15: sReturn = Fifteen; break; case 16: sReturn = Sixteen; break; case 17: sReturn = Seventeen; break; case 18: sReturn = Eighteen; break; case 19: sReturn = Nineteen; break; } return sReturn; } Thank you

I have already done for number to words............ I want its opposite code i.e. words to number conversion code

hi There is not simple method to convert number to its text equal ant. Unfortunately the .NET framework does not provide it. Bt u can implement the method easily. try out with this... public string IntegerToWords( long inputNum) { int dig1dig2dig3level=0lasttwothreeDigits; string retval=; string x=; string [] ones={ zero one two three four five six seven eight nine ten eleven twelve thirteen fourteen fifteen sixteen seventeen eighteen nineteen }; string [] tens={ zero ten twenty thirty forty fifty sixty seventy eighty ninety }; string [] thou={  thousand million billion trillion quadrillion quintillion }; bool isNegative= false ; if (inputNum isNegative= true ; inputNum*=-1; } if (inputNum==0) return (zero); string s=inputNum.ToString(); while (s.Length>0) { // Get the three rightmost characters x=(s.Length // Separate the three digits threeDigits= int .Parse(x); lasttwo=threeDigits % 100; dig1=threeDigits / 100; dig2=lasttwo / 10; dig3=(threeDigits % 10); // append a thousand where appropriate if (level>0 && dig1+dig2+dig3>0) { retval=thou[level] +   + retval; retval=retval.Trim(); } // check that the last two digits is not a zero if (lasttwo>0) { if (lasttwo // if less than 20 use ones only retval=ones[lasttwo] +   + retval; else // otherwise use both tens and ones array retval=tens[dig2] +   + ones[dig3] +   + retval; } // if a hundreds part is there translate it if (dig1>0) retval = ones[dig1] +  hundred  + retval; s=(s.Length - 3)>0 ? s.Substring(0s.Length - 3) : ; level++; } while (retval.IndexOf( )>0) retval=retval.Replace(  ); retval=retval.Trim(); if (isNegative) retval=negative  + retval; return (retval); } u can cll to this methode by IntegerToWords( your_number ); regards frm UOM
