TinyIoc register and interface with multiple types

Question

I am trying to register a base interface IService in TinyIoc

Currently I have multiple classes that inherit from Iservice

for example AuthenticationService and RestService both inherit from base class Service which implements Iservice

The way I am doing it is like this, registering each service separately.

container.Register<IAuthenticationService, AuthenticationService>();
container.Register<IRestService, RestService>();

since they both inherit from Service : IService is there a way to register both in one call or do I have to seperately register each service?

There's a overload for the Register method that accepts a Func, that you can use to determine which concrete type do you want to return:

var decision = true;
container.Register<IService>((c, npo) =>
{
    // Change it to whatever logic you need to decide which service should be returned
    if (decision)
        return new AuthenticationService();
    else
        return new RestService();
});

var instance = container.Resolve<IService>();
