Resolving a list of components as a constructor argument

Say I have an interface to define formatting reports:

public interface IFormatter 
{
    string Name {get;}
    Report Format(InputData data);
}

and an implementation of a provider that will format reports for me:

public FormatterProvider : IFormatterProvider
{
    private readonly IList<IFormatter> _formatter;

public FormatterProvider(IList<IFormatter> formatters)
{
    _formatters = formatters;
}

    public IFormatter GetFormatter(string name){ return _formatters.Where(x => x.Name == name); }
}

I know I can register all of the formatters in an assembly using this registration:

container.Register(
    AllTypes.FromAssemblyName("MyCompany.Formatters")
        .BasedOn<IFormatter>()
        .WithService
        .FromInterface()
    );

But, how to I register the provider so that any formatters registered in the container are passed to it's constructor?

Use the subresolver called CollectionResolver.

Container.Kernel.Resolver.AddSubResolver(new CollectionResolver(Container.Kernel, true));

I think you will need to change the IList to IEnumerable to make this work, but not for sure on that.
