C# MVC.Net format currency without decimals
Solution 1
[DisplayFormat(DataFormatString = "{0:C0}")]
This should give you 0 decimals. But automatically rounds! so if you got ,56 it will round up to 1
20000,00 => 20000 €
20000,56 => 20001 €
20000,49 => 20000 €
/edit: I have borrowed an idea from here: c# Decimal to string for currency
If you can convert your float value to decimal, you can use this Extensionmethod to omit the 0. It truncates the decimal and if this truncated value is equal to the original value, it cuts the zeros. If not, it displays 2 digits. I know this is no Dataformat string, but I'm not quiet sure, it can be done in an as simple way as an annotation.
public static string ToCurrencyString(this decimal d)
{
return d.Equals(Decimal.Truncate(d)) ? d.ToString("0 €") : d.ToString("0.00 €");
}
Solution 2
I don't think there is a way to do it that explicitly uses currency formatting, but you can use custom formatting using the #
character: http://msdn.microsoft.com/en-us/library/0c899ak8.aspx
This should work for U.S. currency:
[DisplayFormat(DataFormatString = "{0:$#.##}")]
The #
character only represents a digit if it's needed.

I'm looking for a DataFormatString that will display a float as a currency. But omit the decimal values if they're irrelevant (0's).
At the moment I'm using:
[DisplayFormat(DataFormatString = "{0:C}")]
On my models. This is displaying as a currency correctly. I've not been able to find anywhere that details what changes I need to make to omit the decimal places?
