The "C" (or currency) format specifier is used to convert a number to a string representing a currency amount. Let us see an example. double value = 139.87; Now to display the above number until three decimal places, use (“C3”) currency format specifier.
If the value to be formatted has more than the specified or default number of decimal places, the fractional value is rounded in the result string. If the value to the right of the number of specified decimal places is 5 or greater, the last digit in the result string is rounded away from zero.
string dateString = int. Parse("20120321"). ToString("yyyy/MM/dd");
Specify you want zero decimal places:
String.Format("{0:C0}", item.DonationAmount)
if item.DonationAmount is a non-nullable decimal then you could just do:
item.DonationAmount.ToString("c0");
if item.DonationAmount is a nullable decimal that you checked has a value then you could do:
item.DonationAmount.Value.ToString("c0");
or in a newer version of C#, which doesn't require you to check if it has a value:
item.DonationAmount?.ToString("c0");
decimal value = 0.00M;
value = Convert.ToDecimal(12345.12345);
