Specify the culture in the call to Format:
在调用中指定区域性Format：
decimal value = 123.45M;
CultureInfo us = CultureInfo.GetCultureInfo("en-US");
string s = string.Format(us, "{0:C}", value);

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
或者
NumberFormatInfo info = new NumberFormatInfo ();
info.CurrencySymbol = "EUR";
Console.WriteLine (String.Format (info, "{0:C}", 45M));

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...
货币符号由 CultureInfo.CurrentCulture.NumberFormat.CurrencySymbol 定义。该属性是读/写的，但如果您尝试更改它，您可能会遇到异常，因为 NumberFormatInfo.IsReadOnly 将为 true...
Alternatively, you could format the number by explicitly using a specific NumberFormatInfo :
或者，您可以通过显式使用特定的 NumberFormatInfo 来格式化数字：
NumberFormatInfo nfi = (NumberFormatInfo)CultureInfo.CurrentCulture.NumberFormat.Clone();
nfi.CurrencySymbol = "$";
String.Format(nfi, "{0:C}", item.Amount);

If you change the displayed currency of an amount, then you are changing its unit of measurement too. ￡1 <> 1 <> $1. Are you absolutely sureof the business requirement here?
如果您更改金额的显示货币，那么您也在更改其计量单位。￡1 <> 1 <> $1。您绝对确定这里的业务需求吗？
