3位货币code到货币符号 [英] 3 Digit currency code to currency symbol

问题描述

在C＃是有可能得到一个货币符号，如£，从3字符货币code，在这种情况下，英镑？

In C# is it possible to get a currency symbol, like '£', from the 3 character currency code, in this case 'GBP'?

Is this possible either in SQL Server or in C#?

推荐答案

虽然有点蛮力，而不是特别优雅，你可以做这样的：

While a bit brute-force and not particularly elegant, you could do it like this:

public bool TryGetCurrencySymbol(string ISOCurrencySymbol, out string symbol)
{
    symbol = CultureInfo
        .GetCultures(CultureTypes.AllCultures)
        .Where(c => !c.IsNeutralCulture)
        .Select(culture => {
            try{
                return new RegionInfo(culture.LCID);
            }
            catch
            {
                return null;
            }
        })
        .Where(ri => ri!=null && ri.ISOCurrencySymbol == ISOCurrencySymbol)
        .Select(ri => ri.CurrencySymbol)
        .FirstOrDefault();
    return symbol != null;
}

和使用它，如下所示：

string currSymbol;
if(TryGetCurrencySymbol("GBP",out currSymbol))
{
    Console.WriteLine("symbol is {0}", currSymbol);
}

如果您预计锤击这种方法，也许是更好地建设一个高速缓存前面：

If you anticipate hammering this method, perhaps it's better to build a cache up front:

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.LCID);
                }
                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);
    }
}
