Autofac - 在运行时解析 IEnumerable 通用接口

我找到了如何使用下面的代码在运行时解析通用接口。我将如何解析 IGenericInterface<> 的所有实例以在运行时取回集合。我知道在 autofac 中我们应该使用 IEnumerable 但我不知道如何在下面的示例中表示它：

 var typeInRuntime = typeof (SubClass1);
 var instance1 = container.Resolve(typeof(IGenericInterface<>)
                          .MakeGenericType(typeInRuntime));

这显然不起作用

 var typeInRuntime = typeof (SubClass1);
 var collection = container
                .Resolve(IEnumerable<typeof(IGenericInterface<>)
                .MakeGenericType(typeInRuntime)>);

原文

I found out how to resolve at runtime a generic interface using the below code. How would I resolve ALL instances of IGenericInterface<> to get back collection at runtime. I know in autofac we are supposed to use IEnumerable<T> but I don't know how to represent that in the below example:

 var typeInRuntime = typeof (SubClass1);
 var instance1 = container.Resolve(typeof(IGenericInterface<>)
                          .MakeGenericType(typeInRuntime));

This does not work obviously

 var typeInRuntime = typeof (SubClass1);
 var collection = container
                .Resolve(IEnumerable<typeof(IGenericInterface<>)
                .MakeGenericType(typeInRuntime)>);

您必须分两步构建通用 IEnumerable 类型。以下代码适用于我的机器；）

var t1 = typeof (IGenericInterface<>).MakeGenericType(typeof(SubClass1));
var t2 = typeof(IEnumerable<>).MakeGenericType(t1);
var collection = c.Resolve(t2);

Assert.That(collection, Is.InstanceOf<IEnumerable<IGenericInterface<SubClass1>>>());

You have to build the generic IEnumerable type in two steps. The following code works on my machine ;)

var t1 = typeof (IGenericInterface<>).MakeGenericType(typeof(SubClass1));
var t2 = typeof(IEnumerable<>).MakeGenericType(t1);
var collection = c.Resolve(t2);

Assert.That(collection, Is.InstanceOf<IEnumerable<IGenericInterface<SubClass1>>>());
