How do I convert a decimal to a Google.Type.Money in C#

I have a decimal value in my C# program and I want to convert it to the Google.Type.Money well-known proto type. How can I do this without doing the calculations for the units and nanos manually? Is there an extension method that does this?

Solution

  • If you have the Google.Api.CommonProtos NuGet package installed, the Google.Type.Money type has a DecimalValue property that will automatically convert back and forth with the .NET decimal type.

    create a Google.Type.Money from a decimal:

    var money = new Google.Type.Money { DecimalValue = 123.45m }

    Access the decimal value of a Google.Type.Money:

    var decimalValue = money.DecimalValue;

    Note that Google.Type.Money is implemented with an int64 for the units and an int32 to hold the fractional portion ("nanos"), so there are some legal decimal values in that can't be represented as a Google.Type.Money exactly. Setting DecimalValue will throw in these cases.
