Resolve type without creating object

Question

Here\'s my problem: I have a container where I register concrete types as interfaces.

builder.RegisterType().As

        

Answer 1

If you are using the RegisterType to register your services this is possible. I wrote a quick test that should help you extract the data you need.

private interface IDeleteOrganization
{

}

private class DeleteOrganization : IDeleteOrganization
{

}


[TestMethod]
public void CanResolveConcreteType()
{
    var builder = new ContainerBuilder();

    builder.RegisterType()
        .As();

    using(var container = builder.Build())
    {
        var registration = container.ComponentRegistry
            .RegistrationsFor(new TypedService(typeof (IDeleteOrganization)))
            .SingleOrDefault();

        if (registration != null)
        {
            var activator = registration.Activator as ReflectionActivator;
            if (activator != null)
            {
                //we can get the type
                var type = activator.LimitType;
                Assert.AreEqual(type, typeof (DeleteOrganization));
            }
        }
    }
}
