Changing the Currency via code in c#

I am using the following to display an amount:

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

This display £9.99

which is okay, but what if I want the application to be able to control the currency and to be able to change the currency to day

$9.99

How do I change the currency format via code

If you change the displayed currency of an amount, then you are changing its unit of measurement too. £1 <> €1 <> $1. Are you absolutely sure of the business requirement here?

The currency symbol is defined by CultureInfo.CurrentCulture.NumberFormat.CurrencySymbol. The property is read/write but you will probably get an exception if you try to change it, because NumberFormatInfo.IsReadOnly will be true...

Alternatively, you could format the number by explicitly using a specific NumberFormatInfo :

NumberFormatInfo nfi = (NumberFormatInfo)CultureInfo.CurrentCulture.NumberFormat.Clone();
nfi.CurrencySymbol = "$";
String.Format(nfi, "{0:C}", item.Amount);

CultureInfo info = new CultureInfo (System.Threading.Thread.CurrentThread.CurrentCulture.LCID);
info.NumberFormat.CurrencySymbol = "EUR";

System.Threading.Thread.CurrentThread.CurrentCulture = info;

Console.WriteLine (String.Format ("{0:C}", 45M));

or

NumberFormatInfo info = new NumberFormatInfo ();
info.CurrencySymbol = "EUR";

Console.WriteLine (String.Format (info, "{0:C}", 45M));

Specify the culture in the call to Format:

    decimal value = 123.45M;
    CultureInfo us = CultureInfo.GetCultureInfo("en-US");
    string s = string.Format(us, "{0:C}", value);
