Is there a way to format the correct currency representation for a country?
Example UK -£127.54 Netherlands € 127,54- USA $127.54
etc..
Some things to consider,
Currency Symbol
Currency symbol placement -- It can be either place before or after the digits.
Negative-amount display

The problem with taking a given number and displaying it with .ToString("C", culture) is that it effectively changes the amount to the default currency of the given culture. If you have a given amount, the ISO currency code of that amount, and you want to display it for a given culture, I would recommend just creating a decimal extension method like the one below. This will not automatically assume that the currency is in the default currency of the culture:
public static string ToFormattedCurrencyString(
this decimal currencyAmount,
string isoCurrencyCode,
CultureInfo userCulture)
{
var userCurrencyCode = new RegionInfo(userCulture.Name).ISOCurrencySymbol;
if (userCurrencyCode == isoCurrencyCode)
{
return currencyAmount.ToString("C", userCulture);
}
return string.Format(
"{0} {1}",
isoCurrencyCode,
currencyAmount.ToString("N2", userCulture));
}
This will either use the local currency symbol or the ISO currency code with the amount -- whichever is more appropriate. More on the topic in this blog post.
public static string ToFormattedCurrencyString(
this decimal currencyAmount,
string isoCurrencyCode,
CultureInfo userCulture)
{
var userCurrencyCode = new RegionInfo(userCulture.Name).ISOCurrencySymbol;
if (userCurrencyCode == isoCurrencyCode)
{
return currencyAmount.ToString("C", userCulture);
}
return string.Format(
"{0} {1}",
isoCurrencyCode,
currencyAmount.ToString("N2", userCulture));
}
This code- (sets currency to GB(Britain/UK/England/£) then prints a line. Then sets currency to US/$ and prints a line)
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-GB",false);
Console.WriteLine("bbbbbbb {0:c}",4321.2);
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US",false);
Console.WriteLine("bbbbbbb {0:c}",4321.2);
Will display-
bbbbbbb £4,321.20
bbbbbbb $4,321.20
For a list of culture names e.g. en-GB en-US e.t.c.

If you just have the currency symbol and the number of decimal places, you can use the following helper function, which respects the symbol/amount order, separators etc, only changing the currency symbol itself and the number of decimal places to display to.
public static string FormatCurrency(string currencySymbol, Decimal currency, int decPlaces)
{
NumberFormatInfo localFormat = (NumberFormatInfo)NumberFormatInfo.CurrentInfo.Clone();
localFormat.CurrencySymbol = currencySymbol;
localFormat.CurrencyDecimalDigits = decPlaces;
return currency.ToString("c", localFormat);
}
This kind of functionality is built in.
When using a decimal you can use a format string "C" or "c".
decimal dec = 123.00M;
string uk = dec.ToString("C", new CultureInfo("en-GB")); // uk holds "£123.00"
string us = dec.ToString("C", new CultureInfo("en-US")); // us holds "$123.00"
