        .Reg

If you have a slightly more complicated scenario where different arrays of values have to be used in different places, then you can use ResolvedArrayParameter, e.g.

container.RegisterType("foo");
container.RegisterType("bar");
container.RegisterType("baz");
container.RegisterType("boo");

container.RegisterType("c1",
    new InjectionConstructor(
        new ResolvedArrayParameter(
            new ResolvedParameter("foo"),
            new ResolvedParameter("bar"))));

container.RegisterType("c2",
    new InjectionConstructor(
        new ResolvedArrayParameter(
            new ResolvedParameter("baz"),
            new ResolvedParameter("boo"))));

var c1 = container.Resolve("c1");
var c1 = container.Resolve("c2");
