Hi!!!!
how can I convert words into numerals...
for Example we enter "One crore twenty lakh thirty four thousand seven hundred eighty four" ,
then its corresponding numeral should be "12034784".

What will be the C# code for finding corresponding numerals for range 0 to 999999999 .....
I mean kindly give me general code applicable for all values.........
