How do I format a double to currency rounded to the nearest dollar?

Question

Right now I have

double numba = 5212.6312 String.Format("{0:C}", Convert.ToInt32(numba) ) 

This will give me

$5,213.00 

but I don't want the ".00".

I know I can just drop the last three characters of the string every time to achieve the effect, but seems like there should be an easier way.

Answer 1

First - don't keep currency in a double - use a decimal instead. Every time. Then use "C0" as the format specifier:

decimal numba = 5212.6312M; string s = numba.ToString("C0"); 

Answer 2

This should do the job:

String.Format("{0:C0}", Convert.ToInt32(numba)) 

The number after the C specifies the number of decimal places to include.

I suspect you really want to be using the decimal type for storing such numbers however.
