在C#中,有可能从3个字符的货币代码中获得货币符号,例如"£",在这种情况下是"GBP"吗？
这可能在SQL Server或C#中吗？

虽然有点蛮力但不是特别优雅,你可以这样做:
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,可能最好先建立一个缓存:
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);
}
}

.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,它不可能直接来自"GBP"等等.
通过RegionInfo货币代码也可以获得相同的信息:
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
我想可以想象一下,可以使用它来构建从ISO代码到符号的地图.
文化名称列表在这里是可用的.
编辑:这似乎工作:
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,这不会产生全面的列表.特别是,它不包括已被欧元取代的旧欧元区货币.我无法看到任何解决方法,但如果您需要,可以手动添加此类货币,例如SymbolsByCode.Add("FRF", "?");法国法郎.

试试这个代码。输入“USD”作为货币代码和所有其他代码。
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;
}
RegionInfo类有一个CurrencySymbol属性,所以它在C#中是可行的.如果您想在Sql Server中执行此操作,则可以使用C#存储过程.
RegionInfo regionInfo = new RegionInfo("GB");
Console.WriteLine(regionInfo.CurrencySymbol); // £
(您需要使用ISO国家/地区代码)
这在Windows Phone应用程序CultureInfo.GetCultures上不起作用,因为平台上没有(至少现在还没有).因此,这是一个快速而肮脏的解决方案 - 在费用者的答案的帮助下制作,其中包含当日的所有文化代码和货币.
public static class CurrencyHelper
{
public static string GetCurrencySymbol(string code)

if (Currencies.ContainsKey(code))
{
return Currencies[code];
}
else

return code;
