Question

Lets say you have a Class with 300 properties with no backing variables, each of those properties returns a decimal/double.

Example:

public decimal MathValue { get; set; }

Now you decided that each one of those values should be rounded.

I am looking for the simplest way to refactor this without having to rewrite all of those properties.

Something, of this equivalent that actually works :D:

public decimal MathValue { get {return Math.Round(MathValue);} set; }

Answer 1

You could create a new value type that pretends to be a decimal, but returns the rounded value. Something like this:

struct RoundedDecimal
{
    public decimal Value { get; private set; }

    public RoundedDecimal(decimal value) : this()
    {
        this.Value = value;
    }

    public static implicit operator decimal(RoundedDecimal d)
    {
        return Math.Round(d.Value);
    }
}

Each property in your class should be of type RoundedDecimal instead of decimal.
