TeixeiraSoftware.Finance.Currency

A simple cross platform currency class library for .Net, that follows the ISO 4217 standard.

The implementation of this library is compatible with .Net Standard 2.0 (see https://docs.microsoft.com/en-us/dotnet/standard/net-standard for details).

This package depends on TeixeiraSoftware.Finance.ICurrency.

Usage

You can get a currency instance by three different ways:

• Calling a factory property, where XXX is the three letters ISO code of the currency:

var currency = Currency.XXX;

• Using the ByAlphabeticCode method, where, again, XXX is the three letters ISO code of the currency:

var currency = Currency.ByAlphabeticCode("XXX");

• Using the ByNumericCode method, where 999 is the three numbers ISO code of the currency:

// Note that the numeric code is a string
var currency = Currency.ByNumericCode("999");

Properties

The Currency struct have five read only properties:

public partial struct Currency : ICurrency, IComparable, IComparable<ICurrency>
{
    // The alphabetic ISO code of the currency
    // This property is always the same as AlphabeticCode
    public string Symbol { get; }

    // The name of the currency
    public string Name { get; }

    // The alphabetic ISO code of the currency
    // This property is always the same as Symbol
    public string AlphabeticCode {
        get {
            return Symbol;
        }
    }

    // The ISO numeric code of the currency
    public string NumericCode { get; }

    // The minor units of the currency
    public byte MinorUnits { get; }

    // The sign symbol of the currency
    public string Sign { get; }
}

Comparing currencies

The available comparison operators are == and !=. The .Equals method is also available.

// returns true
var areCurrenciesEquivalent = (Currency.XXX == Currency.XXX);

// returns false
var areCurrenciesEquivalent = (Currency.XXX != Currency.XXX);

Listing all the currencies

You can use the Currency.AllCurrencies property to get a list of all the currencies:

var allCurrencies = Currency.AllCurrencies;

foreach (var currency in allCurrencies)
{
    var currencyName = currency.Name;
    var currencyISOAlphabeticCode = currency.AlphabeticCode;
    var currencyISONumericCode = currency.NumericCode;
    var currencyMinorUnits = currency.MinorUnits;
    var currencySign = currency.Sign;
}
