3 位货币代码到货币符号

【中文标题】3 位货币代码到货币符号【英文标题】：3 Digit currency code to currency symbol 【发布时间】：2012-09-04 14:59:48 【问题描述】：在 C# 中，是否可以从 3 个字符的货币代码（在本例中为“GBP”）获取货币符号，例如“£”？
这在 SQL Server 或 C# 中是否可行？
【问题讨论】：
您可以随时编写自己的方法 但是我需要为世界上所有的货币创建一个映射。 使用RegionInfo可以使用ISO 2字符代码。
【参考方案1】：
虽然有点蛮力而且不是特别优雅，但您可以这样做：
public bool TryGetCurrencySymbol(string ISOCurrencySymbol, out string symbol)
symbol = CultureInfo
.GetCultures(CultureTypes.AllCultures)
.Where(c => !c.IsNeutralCulture)
.Select(culture =>
try
return new RegionInfo(culture.Name);
catch
return null;
)
.Where(ri => ri!=null && ri.ISOCurrencySymbol == ISOCurrencySymbol)
.Select(ri => ri.CurrencySymbol)
.FirstOrDefault();
return symbol != null;
并按如下方式使用：
string currSymbol;
if(TryGetCurrencySymbol("GBP",out currSymbol))
Console.WriteLine("symbol is 0", currSymbol);
如果您预计会采用这种方法，那么最好先构建一个缓存：
public static class CurrencyTools
private static IDictionary<string,string> map;
static CurrencyTools()
map = CultureInfo
.GetCultures(CultureTypes.AllCultures)
.Where(c => !c.IsNeutralCulture)
.Select(culture =>
try
return new RegionInfo(culture.Name);
catch
return null;
)
.Where(ri => ri!=null)
.GroupBy(ri => ri.ISOCurrencySymbol)
.ToDictionary(x => x.Key, x => x.First().CurrencySymbol);
public static bool TryGetCurrencySymbol(
string ISOCurrencySymbol,
out string symbol)
return map.TryGetValue(ISOCurrencySymbol,out symbol);

@spender 精彩回复！！ @spender，我使用了您的方法，并使用仅过滤特定文化类型来删除 try/catch 块 CultureInfocultureInfo = CultureInfo.GetCultures(CultureTypes.InstalledWin32Cultures|CultureTypes.SpecificCultures) .FirstOrDefault(c => ! c.IsNeutralCulture && !c.Equals(CultureInfo.InvariantCulture) && new RegionInfo(c.LCID).ISOCurrencySymbol == _currency.IsoLetterCode) ??CultureInfo.CurrentCulture; .Select 可以简化而不会抛出异常： .Select(culture => string.IsNullOrWhiteSpace(culture.Name) ? null : new RegionInfo(culture.Name))【参考方案2】：.NET 有CultureInfo.NumberFormat.CurrencySymbol
CultureInfo us = new CultureInfo("en-US");
CultureInfo gb = new CultureInfo("en-GB");
CultureInfo fr = new CultureInfo("fr-FR");
Console.Out.WriteLine(us.NumberFormat.CurrencySymbol); // $
Console.Out.WriteLine(gb.NumberFormat.CurrencySymbol); // £
Console.Out.WriteLine(fr.NumberFormat.CurrencySymbol); // €
但这需要文化名称，而不是"GBP"。据我所知，直接来自"GBP" 等是不可能的。
同样的信息也可以通过RegionInfo获得，以及货币代码：
RegionInfo us = new RegionInfo("en-US");
RegionInfo gb = new RegionInfo("en-GB");
RegionInfo fr = new RegionInfo("fr-FR");
Console.Out.WriteLine(us.CurrencySymbol); // $
Console.Out.WriteLine(gb.CurrencySymbol); // £
Console.Out.WriteLine(fr.CurrencySymbol); // €
Console.Out.WriteLine(us.ISOCurrencySymbol); // USD
Console.Out.WriteLine(gb.ISOCurrencySymbol); // GBP
Console.Out.WriteLine(fr.ISOCurrencySymbol); // EUR
我想人们可以使用它来构建从 ISO 代码到符号的映射。
文化名称列表可用here。
编辑：这似乎可行：
public static class CurrencyCodeMapper
private static readonly Dictionary<string, string> SymbolsByCode;
public static string GetSymbol(string code) return SymbolsByCode[code];
static CurrencyCodeMapper()
SymbolsByCode = new Dictionary<string, string>();
var regions = CultureInfo.GetCultures(CultureTypes.SpecificCultures)
.Select(x => new RegionInfo(x.LCID));
foreach (var region in regions)
if (!SymbolsByCode.ContainsKey(region.ISOCurrencySymbol))
SymbolsByCode.Add(region.ISOCurrencySymbol, region.CurrencySymbol);
用法：
CurrencyCodeMapper.GetSymbol("USD") // $
CurrencyCodeMapper.GetSymbol("GBP") // £
CurrencyCodeMapper.GetSymbol("EUR") // €
当然，请注意，这不会产生一个完整的列表。特别是，它不包括已被欧元取代的旧欧元区货币。我看不到任何解决方法，只能在需要时手动添加此类货币，例如 SymbolsByCode.Add("FRF", "₣"); 表示法郎。
【讨论】：
这是迄今为止此页面上最优雅的答案！构建时的缓存将使其比所有其他需要多次查找的解决方案更快。 最佳答案（在编辑部分之后）！谢谢，verdesmarald！ 我收到了ArgumentException: Customized cultures cannot be passed by LCID, only by name.Parameter name: culture。简单的解决方法是将.LCID 替换为.Name。似乎工作。【参考方案3】：
RegionInfo 类有一个CurrencySymbol property，所以它在 C# 中是可行的。如果您想在 Sql Server 中执行此操作，或许可以使用 C# 存储过程。
RegionInfo regionInfo = new RegionInfo("GB");
Console.WriteLine(regionInfo.CurrencySymbol); // £
（您需要使用ISO country codes）
【讨论】：
RegionInfo 类也有 ISOCurrencySymbol，它是三字母代码。所以这也是我的建议。诀窍是有效地从可用区域中获取具有特定 ISO 货币代码的区域。【参考方案4】：这不适用于 Windows Phone 应用程序，因为CultureInfo.GetCultures 在平台上不可用（至少目前还没有）。因此，这是一个快速而肮脏的解决方案 - 在花费者的答案的帮助下完成，其中包含日期的所有文化代码和货币。

【参考方案5】：试试这个代码。输入“USD”作为 CurrencyCode 和所有其他。
public string getCurrencySymbol(string CurrencyCode)
string symbol = string.Empty;
CultureInfo[] cultures = CultureInfo.GetCultures(CultureTypes.SpecificCultures);
IList Result = new ArrayList();
foreach (CultureInfo ci in cultures)
RegionInfo ri = new RegionInfo(ci.LCID);
if (ri.ISOCurrencySymbol == CurrencyCode)
symbol = ri.CurrencySymbol;
return symbol;
return symbol;
【讨论】：
绝对是一个答案。【参考方案6】：在这个帖子的帮助下，我做了一个短字符串扩展方法
public static string ToCurrencySymbol(this string ISOCurrency)
RegionInfo region = CultureInfo.GetCultures(CultureTypes.SpecificCultures).Select(x => new RegionInfo(x.LCID)).FirstOrDefault(p => p.ISOCurrencySymbol == ISOCurrency);
return region?.ISOCurrencySymbol ?? ISOCurrency;
【讨论】：
return region?.ISOCurrencySymbol ?? ISOCurrency; 应更改为 return region?.CurrencySymbol ?? ISOCurrency;，因为 ISOCurrencySymbol 返回 3 位货币代码【参考方案7】：
这个答案将@spender 的代码（稍加调整）放在一个实用程序类中，该类尝试将三字母 ISO 货币代码转换为其当前流通的符号。为了提高效率，这个类使用了所有先前请求的内部缓存，@spender 也建议这样做。
public static class CurrencySymbolMapper
/// <summary>An internal cache of previously looked up currencies.</summary>
private static Dictionary<string, string> _currencySymbolsCache =
new Dictionary<string, string> (StringComparer.CurrentCultureIgnoreCase);
public static string TryGetCurrencySymbol(string threeLetterISOAlphabeticCode)
// TODO: Enhance to get rid of the silent exception that gets thrown when constructing a new RegionInfo(CultureInfo.LCID) temporary object
if (threeLetterISOAlphabeticCode.Length != 3) return string.Empty;
if (_currencySymbolsCache.ContainsKey(threeLetterISOAlphabeticCode))
return _currencySymbolsCache[threeLetterISOAlphabeticCode];
string currencySymbolSearchResult = string.Empty;
try
currencySymbolSearchResult =
CultureInfo.GetCultures(CultureTypes.AllCultures)
.Where(c => !c.IsNeutralCulture)
.Select(culture =>
try return new RegionInfo(culture.LCID);
catch return null; // Ignore this error, but enhance future implementation to get ride of this silent exception
)
.Where(ri => ri != null && string.Equals(ri.ISOCurrencySymbol, threeLetterISOAlphabeticCode, StringComparison.OrdinalIgnoreCase))
.Select(ri => ri.CurrencySymbol)
.FirstOrDefault();
catch (Exception e)
// TODO: Handle error
if (currencySymbolSearchResult == null) currencySymbolSearchResult = string.Empty;
// Saves both valid and invalid search results, just in case users hammer this method with
// the same invalid request many times
_currencySymbolsCache.Add(threeLetterISOAlphabeticCode, currencySymbolSearchResult);
return currencySymbolSearchResult;
【讨论】：
【参考方案8】：public static string GetCurrencySymbol(string code)
System.Globalization.RegionInfo regionInfo = (from culture in System.Globalization.CultureInfo.GetCultures(System.Globalization.CultureTypes.InstalledWin32Cultures)
where culture.Name.Length > 0 && !culture.IsNeutralCulture
let region = new System.Globalization.RegionInfo(culture.LCID)
where String.Equals(region.ISOCurrencySymbol, code, StringComparison.InvariantCultureIgnoreCase)
select region).First();
return regionInfo.CurrencySymbol;
【讨论】：
【参考方案9】：这就是我得到的方式 声明 @CultureCode varchar(10) = 'en-us'
SELECT SUBSTRING(FORMAT(CONVERT(money,0), 'C', @CultureCode ),1,1) CurrencySymbol
