如何在C＃中使用自定义数字格式字符串显示点

Question

I want to display decimal product price in format 100 грн. (Ukrainian hryvnia). When I use currency pattern .ToString("c") I get ₴ sign, I don't want to use it, so I decided to try something like .ToString("#.## грн.") but the dot isn't displayed. I get грн output but expect грн. . How can I accomplish that? I want to use string pattern as the part of the localization so I could use something like .ToString(Settings.CurrencyOutputPattern) where CurrencyOutputPattern is "c" for USD , "#.## грн." for UAH and "#.## руб." for RUB

Answer 1

You can include a literal . by enclosing it in single quotes:

.ToString("#.## грн'.'")

Answer 2

you can implement your own extension of String/Decimal to make it to grivan

public string ToGrivna(this decimal ammount)
{
    return ammount.ToString("0.##")+" грн."
}

Answer 3

If what you want is to change the currency, then you can clone the CurrentCulture and modify it.

CultureInfo culture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
culture.NumberFormat.CurrencySymbol = "грн.";

decimal num = 10.24M;
string str = num.ToString("c", culture);

If you want to control where the currency is written (left o right), there are two properties of NumberFormat : NumberFormatInfo.CurrencyPositivePattern and NumberFormatInfo.CurrencyNegativePattern

For example here in Italy we use € 10.00
