Parse value with Currency symbol

Question

I have looked to multiple SO questions on parsing currency, the best (recommended) way seems to be the one I\'m trying below:

var payout = decimal.Parse(\"$2.10\         


        

Answer 1

I've expounded on Hari Prasad's answer. With this you can minimize the culture result. Update "SupportedCultures" with the ones you might use in your app.

    private static readonly List SupportedCultures = new List {"en-US", "en-GB", "fr-FR"};

    public static void Main()
    {
        var (amount, culture) = ParseCurrencyWithSymbol("$256.12");
        Console.WriteLine($"{culture?.Name} | {amount}");

        var (amount2, culture2) = ParseCurrencyWithSymbol("£389.17");
        Console.WriteLine($"{culture2?.Name} | {amount2}");

        var (amount3, culture3) = ParseCurrencyWithSymbol("€421,10");
        Console.WriteLine(culture3 != null ? $"{culture3.Name} | {amount3}" : "Failed!");
    }

    public static Tuple ParseCurrencyWithSymbol(string input)
    {
        var culture = CultureInfo.GetCultures(CultureTypes.AllCultures)
            .Where(x => SupportedCultures.Contains(x.Name))
            .FirstOrDefault(c => input.Contains(c.NumberFormat.CurrencySymbol));

        if (culture == null) return new Tuple(null, null);

        return new Tuple(decimal.Parse(input,
            NumberStyles.Currency | NumberStyles.AllowCurrencySymbol |
            NumberStyles.AllowDecimalPoint | NumberStyles.AllowThousands, culture), culture);
    }
