How can I format decimal property to currency?

Question

I want to format a decimal value as a currency value.

How can I do this?

Answer 1

You can use String.Format, see the code [via How-to Geek]:

decimal moneyvalue = 1921.39m;
string html = String.Format("Order Total: {0:C}", moneyvalue);
Console.WriteLine(html);
// Output: $1,921.39

Answer 2

Properties can return anything they want to, but it's going to need to return the correct type.

private decimal _amount;

public string FormattedAmount
{
    get { return string.Format("{0:C}", _amount); }
}

Question was asked... what if it was a nullable decimal.

private decimal? _amount;

public string FormattedAmount
{
    get
    {
         return _amount == null ? "null" : string.Format("{0:C}", _amount.Value);
    }
}
