使用Unity注射阵列 [英] Injecting arrays with Unity

问题描述

我的目标是构造器注入实现接口的对象的数组。

My goal is to constructor inject an array of objects implementing an interface.

以下是我现在有它的方式。

The following is the way I currently have it.

            Container

                    .RegisterInstance<Company>(ParseCompany(args[1])

                    .RegisterInstance<eTargets>(ParseTargets(args[2]))

                    .RegisterInstance<ILoader[]>(new ILoader[] {
                        Container.Resolve<CustomerLoader>(),
                        Container.Resolve<PaymentLoader(),
                        Container.Resolve<InvoiceLoader() 
                    });

它是典型的呼叫解决容器配置这种方式还是有来完成同样的事情？

Is it typical to call Resolve in container configuration this way or is there a more standard way to accomplish the same thing?

推荐答案

统一的本地了解到阵列，所以没有理由做起来很复杂。只要注册了 ILoaders 要包括和解决对象通常图形。 自动布线会照顾其余的：

Unity natively understands arrays, so there's no reason to make it so complicated. Just register the ILoaders you want to include and resolve the object graphs normally. Auto-wiring will take care of the rest:

container.RegisterType<ILoader, FooLoader>("foo");
container.RegisterType<ILoader, BarLoader>("bar");
container.RegisterType<ILoader, BazLoader>("baz");

var c = container.Resolve<MyConsumer>();

假设 MyConsumer 构造像定义这样的：

public MyConsumer(ILoader[] loaders)

然而，你应该知道，（对于一些深不可测的原因），统一只包含的命名的这样的组件。该的默认的组件：

However, you should be aware that (for some unfathomable reason) Unity only includes named components in this way. The default component:

container.RegisterType<ILoader, Loader>();

会的不的被包含在数组中，因为它没有名字。

will not be included in the array, since it has no name.
