How to convert numeric value in words at runtime

Code for converting numeric values in words is pretty simple. I had developed the code and using it from last few months and now to help others i am posting it here. There are 4 fucntions and each doing its on work. So i am just describing the procedure in 4 simple steps as below..

Step 1) Declare these variables in your code file

string Number;

string deciml;

string _number;

string _deciml;

string[] US = new string[1003];

string[] SNu = new string[20];

string[] SNt = new string[10];

Step 2) Call Initialize() function in your page_load event as

protected void Page_Load(object sender, EventArgs e)

{

Initialize();

}

Step 3) Call myfunction(string myNumber) function to get your number in words. You have to pass the value in the string form to this function as

string NumberInWords = myfunction("123.25");

Step 4) Copy and paste the below code in your code file

//-----------code to convert numeric value in words---------------------

//this will convert number(upto 2 decimal places like 123.15) into words

public string myfunction(string myNumber)

{

string number_in_words = "";

string currency = "Rs. ";

string _currency = " Paise Only";

if (Convert.ToDouble(myNumber) == 0)

{

number_in_words = "Null Value";

}

if (Convert.ToDouble(myNumber) < 0)

{

number_in_words = "Invalid Value";

}

if (myNumber.Split('.').Length > 1) { } else { myNumber = myNumber + ".00"; }

string[] no = myNumber.Split('.');

if ((no[0] != null) && (no[1] != "00"))

{

Number = no[0];

deciml = no[1];

_number = (NameOfNumber(Number));

_deciml = (NameOfNumber(deciml));

number_in_words = currency + _number.Trim() + " and " + _deciml.Trim() + _currency;

}

if ((no[0] != null) && (no[1] == "00"))

{

Number = no[0];

_number = (NameOfNumber(Number));

number_in_words = currency + _number + "Only";

}

if ((Convert.ToDouble(no[0]) == 0) && (no[1] != null))

{

deciml = no[1];

_deciml = (NameOfNumber(deciml));

number_in_words = _deciml + _currency;

}

return number_in_words;

}

public string NameOfNumber(string Number)

{

string GroupName = "";

{

}

{

}

else
