Castle Windsor: Can I get all instances of a type?

I am registering a bunch of ITask implementations with Windsor using N开发者_JAVA百科amed to separate them. Is there a way a class can request all instances of ITask?

Windsor can do what you request via the CollectionResolver subdependency resolver:

var container = new WindsorContainer();
var kernel = container.Kernel;
kernel.Resolver.AddSubResolver(new CollectionResolver(kernel));

Now, if you register multiple implementations of ITask, your task runner can have a ctor like this:

public TaskRunner(IEnumerable<ITask> tasks)
{
    // ...
}

which is what you want, right?

Yes,

container.ResolveAll<ITask>()
