格式化货币

在下面的示例中，逗号是小数点分隔符。

我有这个：125456,89

我想要这个：125.456,89；其他示例：23456789,89 => 23.456.789,89

Thanks,

看看这个例子

double value = 12345.6789;
Console.WriteLine(value.ToString("C", CultureInfo.CurrentCulture));

Console.WriteLine(value.ToString("C3", CultureInfo.CurrentCulture));

Console.WriteLine(value.ToString("C3", 

              CultureInfo.CreateSpecificCulture("da-DK")));

// The example displays the following output on a system whose
// current culture is English (United States):
//       $12,345.68
//       $12,345.679
//       kr 12.345,679
