Question

i have a method that looks like this:

   private double GetX()
    {
        if (Servings.Count > 0)
        {
            return Servings[0].X;
        }
        if (!string.IsNullOrEmpty(Description))
        {
            FoodDescriptionParser parser = new FoodDescriptionParser();
            return parser.Parse(Description).X;
        }
        return 0;
    }

and i have another method that looks like this:

  private double GetY()
    {
        if (Servings.Count > 0)
        {
            return Servings[0].Y;
        }
        if (!string.IsNullOrEmpty(Description))
        {
            FoodDescriptionParser parser = new FoodDescriptionParser();
            return parser.Parse(Description).Y;
        }
        return 0;
    }

Is there any way to consolidate this as the only thing different is the property names?

Answer 1

Make a separate GetServing method:

private Serving GetServing() {
    if (Servings.Count > 0)
        return Servings[0];

    if (!string.IsNullOrEmpty(Description)) {
        FoodDescriptionParser parser = new FoodDescriptionParser();
        return parser.Parse(Description);
    }
    return null;
}

private double GetX() {
    Serving serving = GetServing();
    if (serving == null) return 0;
    return serving.X;
}

private double GetY() {
    Serving serving = GetServing();
    if (serving == null) return 0;
    return serving.Y;
}
