货币格式 [英] Currency formatting

问题描述

这应该是一个简单的问题，但...

This should be an easy problem but...

我需要的格式在C＃显示器（串）的货币

I need to format a currency for display (string) in C#

在考虑中的货币将有自己的规则，如使用的符号，如果该符号应该前值（例如$ 10）或后（如10₫这是越南盾）。

The currency in question will have its own rules such as the symbol to use and if that symbol should come before the value (e.g. $ 10) or after (e.g. 10 ₫ which is Vietnamese Dong).

但如何将数字的格式取决于用户的地方，而不是货币。

But how the numbers are formatted depends upon the users local, not the currency.

例如。

1.234,56 ₫ should be displayed to a user in Vietnam but 
1,234.56 ₫ should be displayed to a user in the US

（格式为code所以很容易看到的差异，和。）的

所以，code像

Double vietnamTotal = 1234.56;
return vietnamTotal.ToString("c");

不会工作，因为它会使用用户（或更为准确CultureInfo.CurrentCulture）区域的格式和货币，所以你会得到像$ 1,123.56 - 正确使用和。但错误的符号。

Won't work as it will use the users (or more accuratly CultureInfo.CurrentCulture) locale for format and currency so you would get things like $1,123.56 - right use of , and . but wrong symbol.

Double vietnamTotal = 1234.56;
CultureInfo ci = new CultureInfo(1066); // Vietnam
return vietnameTotal.ToString("c",ci));

请问给1.234,56₫ - 右符号，错误的使用，和。对于当前用户。

Would give 1.234,56 ₫ - Right symbol, wrong use of , and . for current user.

这篇文章<一个href="http://stackoverflow.com/questions/850673/proper-currency-format-when-not-displaying-the-native-currency-of-a-culture">gives在正确的事更详细的事，但不知道如何做到这一点。

This post gives more detail on the right thing to do, but not how to do it.

我缺少什么明显的方法隐藏在框架是什么？

What obvious method hidden in the framework am I missing?

推荐答案

• 取的NumberFormatInfo 从用户的货币，它克隆
• 将 CurrencySymbol 在有关克隆格式的 CurrencySymbol 货币
• 如果要使用的货币位置（和格式的一些其他方面）复制， 设置 CurrencyPositivePattern 和 CurrencyNegativePattern 以相同的方式。
• 使用结果的格式。

• Take the NumberFormatInfo from the user's currency, and clone it
• Set the CurrencySymbol in the cloned format to the CurrencySymbol of the currency in question
• If you want the currency position (and some other aspects of the format) to be copied, set CurrencyPositivePattern and CurrencyNegativePattern in the same way.
• Use the result to format.

例如：

using System;
using System.Globalization;

class Test
{    
    static void Main()
    {
        decimal total = 1234.56m;
        CultureInfo vietnam = new CultureInfo(1066);
        CultureInfo usa = new CultureInfo("en-US");

        NumberFormatInfo nfi = usa.NumberFormat;
        nfi = (NumberFormatInfo) nfi.Clone();
        NumberFormatInfo vnfi = vietnam.NumberFormat;
        nfi.CurrencySymbol = vnfi.CurrencySymbol;
        nfi.CurrencyNegativePattern = vnfi.CurrencyNegativePattern;
        nfi.CurrencyPositivePattern = vnfi.CurrencyPositivePattern;

        Console.WriteLine(total.ToString("c", nfi));
    }
}

诚然我的控制台不管理，以显示正确的符号，但我敢肯定，这只是由于字体问题：）

Admittedly my console doesn't manage to display the right symbol, but I'm sure that's just due to font issues :)
