没有具体类型的 StructureMap 构造函数参数或实例名称的参数

StructureMap Constructor arguments without Concrete type or args by instance name

我确实阅读了其他答案,但 none 完全适合,所以请多多包涵 后台伪代码(无视SM版本)

public interface IFilter() {}

public class A: IFilter {}
public class B: IFilter {}
public class C: IFilter {}
public class D: IFilter {}


public interface IProcessor()
{
}

public Processor(List<IFilter> filters) //List, IEnumerbale, Array doesn't matter 
{
}

ObjectFactory.Initialize(x =>
{
    x.Scan(scanner =>
    {
        ...
        scanner.AddAllTypesOf<IFilter>().NameBy(type => type.Name);
    });
});

如何配置SM默认使用实例"B"和"C"?我可以这样配置,但我不想:

ObjectFactory.Configure(x =>
{
    var filters = new List<IFilter>();
    filters.Add(ObjectFactory.GetNamedInstance<IFilter>("B")); //I don't like create instance before concrete use
    filters.Add(ObjectFactory.GetNamedInstance<IFilter>("C"));
    x.For<IProcessor>().Use(new Processor(filters)); //this works, but I don't like to use concrete type, what if not accessible?
});

有没有办法这样配置(伪)

x.For<IProcessor>().Ctor<List<IFilter>>().ByInstanceName(new[] {"B","C"})
//or assuming only one concrete type is defined for IProcessor
x.For<IProcessor>().Named("Alpha").Ctor<List<IFilter>>().ByInstanceName(new[] {"B","C"});
x.For<IProcessor>().Named("Beta").Ctor<List<IFilter>>().ByInstanceName(new[] {"A","D"});

或者通常在代码参考中不使用具体类型的任何其他方式? 我知道 IProcessor 可能有多个实例,但是 SM 真的没有办法匹配 Ctor 签名并在匹配时使用命名实例连接任何 IProcessor 实例吗?

如果必须使用具体类型,那么至少仍然使用 ctor 的实例名称而不是创建列表

x.For<IProcessor>().Use(new Processor()).WithCtorInstanceByName("B","C");

您要查找的语法是:

For<IProcessor>().Use<Processor>().EnumerableOf<IFilter>().Contains(_ => {
    _.TheInstanceNamed("A");                        
    _.TheInstanceNamed("A"); 
}
