Contextual Binding to class name

[webgio]

Hi,
I would like to use Contextual Binding based on the type of the Target
instead of an attribute.
For Example I have something like:

public class Ninja {
[Inject] public IWeapon MeleeWeapon { get; set; }
}

public class SuperNinja {
[Inject] public IWeapon SuperWeapon { get; set; }
}

so that:

Bind<IWeapon>().To<Sword>();

would be used to bind to Sword by Ninja
and something like:

Bind<IWeapon>().To<Shuriken>().Only(When.Context.Target.Type.Name.EqualTo("SuperNinja")

would be used to bind to Shuriken by SuperNinja

...
Is there a way to do this?

thank you!

This is one of those cases where there are several ways of doing the same thing. The easiest way to bind for members of a certain type is:

Bind<IWeapon>().To<Shuriken>().ForMembersOf<SuperNinja>();

Hi Nate,
I get a NullReferenceException:

[NullReferenceException: Riferimento a un oggetto non impostato su
un'istanza di oggetto.]

Ninject.Core.Binding.StandardBinder.<Ninject.Core.Binding.Syntax.IBindingConditionSyntax.ForMembersOf>b__0(IContext
ctx) +27
Ninject.Core.Infrastructure.PredicateCondition`1.Matches(T value)
+12
Ninject.Core.Binding.StandardBinding.Matches(IContext context) +112

Ninject.Core.Binding.StandardBindingSelector.GetMatchingBindings(IContext
context, IEnumerable`1 candidates) +139
Ninject.Core.Binding.StandardBindingSelector.SelectBinding(Type
service, IContext context) +503
Ninject.Core.KernelBase.ResolveBinding(Type service, IContext
context) +381
Ninject.Core.KernelBase.ResolveInstance(Type service, IContext
context, Boolean isEagerActivation) +298
Ninject.Core.KernelBase.Get() +119

Am I missing something?

thanks,
Giorgio

Interesting...are you using 1.0 or the latest Subversion build?

1.0, should I go with the Subversion build?

If you could, try it with the latest build and let me know if you experience the same error.

Thanks,

Do I need visual studio 2008? I can't compile it on VS 2005... any way to download a setup of the trunk version?...
Thanks,

Sorry Nate, I'm still unable to solve the problem and I can't compile
the trunk version.
I'm getting similar exception if a conditionally bind to an attribute.
Any idea?
Thanks,
Giorgio
