Question

With Ninject, how do you configure the kernel so I can define what constructor values are passing into the instantiation of an object?

I have the following configured in a module:

Bind<IService1>()
    .To<Service1Impl>()
    .InSingletonScope()
    .Named("LIVE");
Bind<IService2>()
    .To<Service2Impl>()
    .InSingletonScope()
    .Named("LIVE")
    .WithConstructorArgument(
        "service1", 
        Kernel.Get<IService1>("LIVE"));

Service2Impl takes a constructor parameter of IService1 but I want this to come from the container. I also want to have named bindings as my code will be targeting different versions at runtime.

This seems to work but is it the right way to achieve what I want to do?
Should I be achieving without the use of named bindings and wiring different configuration modules into the kernel?

EDIT

I have used the ToMethod() method now to specify a delegate to call on request of a specific type. This seems a bit nicer as I’ll get compile time warnings if the constructor configuration is wrong rather than having to know the name of the parameter I am passing first.

Thanks

I used ToMethod in the end, which allowed me to construct the required instance with constructors in order to maintain compile time errors.

For example:

.ToMethod(Func<IContext, T> method)

Bind<IWeapon>().ToMethod(context => new Sword());
