Given registered services:
builder.RegisterType<Foo1>().Named<IFoo>("one").As<IFoo>();
builder.RegisterType<Foo2>().Named<IFoo>("two").As<IFoo>();
builder.RegisterType<Foo3>().Named<IFoo>("three").As<IFoo>();
Can I retrieve named implementations of IFoo
interface by injecting something like Func<string, IFoo>
?
public class SomeClass(Func<string, IFoo> foo) {
var f = foo("one");
Debug.Assert(f is Foo1);
var g = foo("two");
Debug.Assert(g is Foo2);
var h = foo("three");
Debug.Assert(h is Foo3);
}
I know I can do it with Meta<>
, but I don't want to use it.
You could register your own resolving delegate like this:
builder.Register<Func<string, IFoo>>(c =>
{
var cc = c.Resolve<IComponentContext>();
return named => cc.ResolveNamed<IFoo>(named);
});
