String.Format way to format Currency without Cents

I'm disp开发者_如何学JAVAlaying currency using the current method

String.Format("{0:C}", item.DonationAmount)

Which outputs like $10.00

We will be dealing with large dollar amounts, and no cents. We would like the currency to display as $10 without the decimal or zeroes. How can I do this? Removing the currency format makes the number display like 10.0000 :( thanks in advance.

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);
        Console.WriteLine(".ToString(\"C\") Formates With Currency $ Sign");
        Console.WriteLine(value.ToString("C"));
        //OutPut : $12345.12
        Console.WriteLine(value.ToString("C1"));
        //OutPut : $12345.1
        Console.WriteLine(value.ToString("C2"));
        //OutPut : $12345.12
        Console.WriteLine(value.ToString("C3"));
        //OutPut : $12345.123
        Console.WriteLine(value.ToString("C4"));
        //OutPut : $12345.1235
        Console.WriteLine(value.ToString("C5"));
        //OutPut : $12345.12345
        Console.WriteLine(value.ToString("C6"));
        //OutPut : $12345.123450
        Console.WriteLine();
        Console.WriteLine(".ToString(\"F\") Formates With out Currency Sign");
        Console.WriteLine(value.ToString("F"));
        //OutPut : 12345.12

        //OutPut : 12345.1
