TeixeiraSoftware.Finance.Money

TeixeiraSoftware.Finance.Money

Build status license Pull Requests NuGet

A simple cross platform money struct for .Net based on Martin Fowler's Money pattern.

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

TeixeiraSoftware.Finance.Money is an immutable value type.

Installation

NuGet Package Manager:

Install-Package TeixeiraSoftware.Finance.Money

.NET CLI:

dotnet add package TeixeiraSoftware.Finance.Money

Paket CLI:

paket add TeixeiraSoftware.Finance.Money

Dependencies

This package has no dependencies.

Usage

The Money class makes use of an abstract class called ICurrency that must be implemented in order to use this library. There is already an implementation available at nuget using the name TeixeiraSoftware.Finance.Currency, and for the examples in this documentation, the methods used to get ICurrency instances will come from that library. If you want, you can implement yourself the ICurrency abstract class in order to provide your own functionallity (The ICurrency abstract class is part of TeixeiraSoftware.Finance.Money and you can optionally use the implementation provided by TeixeiraSoftware.Finance.Currency).

The usage is very simple:

// XXX represents the ISO 4217 code of the currency
var tenMoneys = new Money(12.3m, Currency.XXX);
var aMillionMoneys = new Money(1000000, Currency.ByAlphabeticCode("XXX"));

Math operations:

+ operator (addition):

When doing addition operations, you can sum an instance of Money directly to a decimal or an integer. The resulting Money instance will have the same currency as the instance used in the addition operation.

var halfMoney = new Money(0.25m, Currency.XXX) + 0.25m;
var tenMoneys = 1.5m + new Money(8.5m, Currency.XXX);
var aHundredMoneys = tenMoneys + 90;
var aThousandMoneys = 900 + aHundredMoneys;

And, of course, you can sum two instances of Money as well:

var moreMoney = aHundredMoneys + aThousandMoneys;
- operator (subtraction):

When doing subtraction operations, you can subtract an instance of Money directly to a decimal or an integer. The resulting Money instance will have the same currency as the instance used in the subtraction operation.

var oneMoney = new Money(2, Currency.XXX) - 1;
var tenMoneys = 1 - new Money(11, Currency.XXX);
var nineMoneys = tenMoneys - 1;
var eightMoneys = 1 - tenMoneys;

And, of course, you can subtract two instances of Money as well:

var sevenMoneys = eightMoneys - oneMoney;
/ operator (division):

You can only divide a Money instace by a factor, that can be a decimal or an integer:

var fiveHundredMoneys = aThousandMoneys / 2;
var someMoney = new Money(1000.01m, Currency.XXX) / 1.28m;

You cannot divide two Money instances, like:

// This will result in a compile time error
new Money(10, Currency.XXX) / new Money(10, Currency.XXX);

You also cannot divide any number to a Money instance, like:

// This will result in a compile time error
var money = 2 / new Money(10, Currency.XXX);

This is because those kind of operations do not make much sense.

* operator (multiplication):

You can only multiply a Money instance by a factor, that can be a decimal or an integer:

var someMoney = aThousandMoneys * 2.5m;
var aLotOfMoney = 1000 * aThousandMoneys;

You cannot multiply two Money instances, because it would not make much sense:

// This will result in a compile time error
var money = new Money(2, Currency.XXX) * new Money(10, Currency.XXX);

Comparison operations

The available operators are: ==, !=, >, >=, < and <=.

The .Equals method is also available.

var aThousandMoneys = new Money(1000, Currency.XXX);
var fortyTwoMoneys = new Money(42, Currency.XXX);
var twoThousandMoneys = aThousandMoneys * 2;
var aLotOfMoneys = 1000 * aThousandMoneys;

if (aThousandMoneys == aLotOfMoneys)
{
    // ...
}

if (aThousandMoneys != new Money(10, Currency.XTS))
{
    // ...
}

if (aThousandMoneys.Equals(twoThousandMoneys))
{
    // ...
}

if (twoThousandMoneys > aLotOfMoneys)
{
    // ...
}

// and so on...

Details about operations involving different currencies

You may pay attention when trying to use the operators when the currencies don't match. the operators >, >=, < and <= will throw a CurrencyMismatchException if the currencies are not the same:

var tenXXX = new Money(10, Currency.XXX);
var tenXTS = new Money(10, Currency.XTS);

if (tenXXX > tenXTS) // throws CurrencyMismatchException

However, you can perform an equality comparison between instances with different currencies, although in this case you will always obtain false:

var tenXXX = new Money(10, Currency.XXX);
var tenXTS = new Money(10, Currency.XTS);

if (tenXXX == tenXTS)
{
    // no exception bill be thrown and the code in this block will never be executed
}

if (tenXXX.Equals(tenXTS))
{
    // no exception bill be thrown and the code in this block will never be executed
}

If you don't like this behavior, you can change it by setting the flag StrictEqualityComparisons to true. When doing so, any try to compare the equality between instances with different currencies will result in a CurrencyMismatchException being thrown:

Money.StrictEqualityComparisons = true;

var tenXXX = new Money(10, Currency.XXX);
var tenXTS = new Money(10, Currency.XTS);

if (tenXXX == tenXTS) // throws CurrencyMismatchException

if (tenXXX.Equals(tenXTS)) // throws CurrencyMismatchException
