I Need to display a number with commas and decimal point.
Eg: Case 1 : Decimal number is 432324 (This does not have commas or decimal Points) Need to display it
Your question is not very clear but this should achieve what you are trying to do:
decimal numericValue = 3494309432324.00m; string formatted = numericValue.ToString("#,##0.00");
Then formatted will contain: 3,494,309,432,324.00
formatted
