#781 – A struct Can Implement an Interface

Like a class, a struct can implement an interface.  In the example below, the DogCollar struct implements the IStrapDimensions interface, which contains a couple of properties and a method.

    public interface IStrapDimensions
    {
        double Length { get; }
        double Width { get; }

        double CalcArea();
    }

    public struct DogCollar : IStrapDimensions
    {
        private double length;
        public double Length
        {
            get { return length; }
        }

        private double width;
        public double Width
        {
            get { return width; }
        }

        public double CalcArea()
        {
            return Length * Width;
        }

        public DogCollar(double len, double wid)
        {
            length = len;
            width = wid;
        }
    }
