Anche se un po' brutale e non particolarmente elegante, potresti farlo in questo modo:
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;
}
e usalo come segue:
string currSymbol;
if(TryGetCurrencySymbol("GBP",out currSymbol))
{
Console.WriteLine("symbol is {0}", currSymbol);
}
Se prevedi di martellare questo metodo, forse è meglio creare una cache in anticipo:
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);
}
}
