Is it possible to parse multiple complex types in a single option?

[sonicbhoc]

I have an application that requires the user to specify some extra data for each option of a certain type, and I'd like them to be able to supply multiple instances of that option.. Essentially, I want to read either 3 or 4 arguments from the CLI per instance of the option.

The type I want to bind is defined as follows:

public class ImageFile
{
    public ImageFile(string path, string name, ushort xPos, ushort yPos)
    {
        Path = path;
        Name = name;
        XPosition = xPos;
        YPosition = yPos;
    }

    public ImageFile(string path, ushort xPos, ushort yPos)
    {
        Path = path;
        Name = System.IO.Path.GetFileNameWithoutExtension(path).Replace(' ', '_').Replace("_-_", "_");
        XPosition = xPos;
        YPosition = yPos;
    }
    public string Path { get; set; }
    public string Name { get; set; }
    public ushort XPosition { get; set; }
    public ushort YPosition { get; set; }
}

And the option is of type Option<IEnumerable<ImageFile>>.

This does not work. I misunderstood the documentation as being able to parse types with constructors of primitive types and for the IEnumerable type to just mean that multiple options with that name can be used in a single command and combined into an enumerable type. Was I mistaken?

Is there any way to do this?
