How to convert words to equivalent numbers?

hii i want to know how to convert number to word  iam not understanding  this code.   Can  u tell me  number to word code  like u write word to number code plz.

Plz Sanjay ,
Kindly reply to my thread..........

Hi,Sanjay
I want to ask one thing....
In this code ,I added for million and billion also.But the problem is that its giving wrong answer for:"One million two hundred eighty six thousand four hundred seventy five"...
Here,I am confused how the system will interpret hundred ,which is occuring just after million ,differently...
How can i modify my code for such input... 
kindly give me some solution for this.......

I want only for minus sign....
I tried adding  hashtable.Add("minus","-");
But its giving error.......
Also if i enter words without spacing................
Its giving zero answer instead I want message box to be dispalyed as"enter values in correct format".......How to handle this exception.........

Hi,

Just add another collection with all possible signs, then find from, check if user enter char is exists in the your sign collection, then add word according that sign to your text box.

Thank you

HI,
iN THIS CODE IF i ENTER "tenthousand" i.e both the words joined together.......
In this case I want to display error message "enter the words with proper spacing"........
Also if someone writes "minus ten thousand" , how to replace minus with its respective sign.

Hi,

As i think u have included this namespace

using System.Collections.Generic;

not

using System.Collections;

Also include this namespace

Hi  ,
I have made small error in spelling which I have corrected........
Now its working fine.
Thanks a lot........
I think people on this forum are very intelligent and helpful..........Because no other forum was able to solve my problem........

Hi , I am using Visual Studio 2008, and I have already included this namespace.........
Still its giving error.......

Hi

include namesapce for the hashtable by using this.

using System.Collections;

Hi  Sanjay,
Its giving error for hashtable:
Error: The type or namespace name 'HashTable' could not be found (are you missing a using directive or an assembly reference?) 
 

Hi,

this is the solution of your problem.

protected void Button1_Click(object sender, EventArgs e)

    {

        Hashtable hashTable = new Hashtable();

        hashTable.Add("one", "1");

        hashTable.Add("two", "2");

        hashTable.Add("three", "3");

        hashTable.Add("four", "4");

        hashTable.Add("five", "5");

        hashTable.Add("six", "6");

        hashTable.Add("seven", "7");

        hashTable.Add("eight", "8");

        hashTable.Add("nine", "9");

        hashTable.Add("ten", "10");

        hashTable.Add("eleven", "11");

        hashTable.Add("twelve", "12");

        hashTable.Add("thirteen", "13");

        hashTable.Add("fourteen", "14");

        hashTable.Add("fifteen", "15");

        hashTable.Add("sixteen", "16");

        hashTable.Add("seventeen", "17");

        hashTable.Add("eighteen", "18");

        hashTable.Add("nineteen", "19");

        hashTable.Add("twenty", "20");

        hashTable.Add("thirty", "30");

        hashTable.Add("fourty", "40");

        hashTable.Add("fifty", "50");

        hashTable.Add("sixty", "60");

        hashTable.Add("seventy", "70");

        hashTable.Add("eighty", "80");

        hashTable.Add("ninety", "90");

        hashTable.Add("hundred", "100");

        hashTable.Add("thousand", "1000");

        hashTable.Add("lakh", "100000");

        hashTable.Add("crore", "10000000");

 

        string wordValue = TextBox1.Text.Trim().ToLower();

 

        string[] strArray = wordValue.Split(' ');

        int value = 0;

        int tempValue = 0;

        foreach (string s in strArray)

        {

 

            if (object.Equals(s, "hundred") || object.Equals(s, "thousand") || object.Equals(s, "lakh") || object.Equals(s, "crore"))

            {

                value += tempValue *  int.Parse(hashTable[s].ToString());

                tempValue = 0;

            }

            else

            {

                if (hashTable.ContainsKey(s))

                {

                    tempValue +=  int.Parse(hashTable[s].ToString());

                }

            }

        }

        TextBox1.Text = (value + tempValue).ToString();

    }

Happy Coding!!

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...........

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 dig1,dig2,dig3,level=0,lasttwo,threeDigits;

  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 < 0) {
    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<3) ? s : s.Substring(s.Length - 3, 3);

    // 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<20) // 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(0,s.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);
