Poslednji IoC kontejner u ovom serijalu je Castle Windsor. Ovaj IoC kontejner je deo Castle projekta iza koga stoji grupa iskusnih .Net developer-a.
Jednostavna implementacija IDependencyResolver interfejsa pomoću Castle Windsor IoC kontejnera bi izgledala ovako:
public class CastleWindsorDependencyResolver : IDependencyResolver
{
private IKernel kernel;
public CastleWindsorDependencyResolver(IKernel kernel)
{
this.kernel = kernel;
}
public object GetService(Type serviceType)
{
try
{
return this.kernel.Resolve(serviceType);
}
catch
{
return null;
}
}
public IEnumerable<object> GetServices(Type serviceType)
{
try
{
return this.kernel.ResolveAll(serviceType).Cast<IEnumerable<object>>();
}
catch
{
return new List<object>();
}
}
}
Na kraju, konfigurisanje Castle Windsor IoC kontejnera treba izvršiti unutar Global.asax.cs fajla:
protected void Application_Start()
{
RegisterCastleWindsorDependencyResolver();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
}
private void RegisterCastleWindsorDependencyResolver()
{
var container = new WindsorContainer()
.Register(Component.For<HomeController>())
.Register(Component.For<IRepository>().ImplementedBy<ConcreteRepository>());
DependencyResolver.SetResolver(
new CastleWindsorDependencyResolver(container.Kernel));
}
