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

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.

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");

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.

Console.WriteLine(numba.ToString("C0"));

I think the right way to achieve your goal is with this:

Thread.CurrentThread.CurrentCulture.NumberFormat.CurrencyDecimalDigits = 0;

and only then you should do the Format call:

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