Structuremap - implementation of several interfaces

Question

I am completely new to Structuremap and confused about how to connect an interface that has several implementations.

Suppose I have Controller1 and Controller2 . I have Interface1 , which is implemented by two separate classes, Class1ForInterface1 and Class2ForInterface1 . In Controller1 I want to enter Class1ForInterface1 and in Controller2 I want Class2ForInterface1 insert Class2ForInterface1 .

How to do this using structure? It seems that I can have only one interface mapping for a particular type?

Thanks!

It is possible that several classes implement the same interface with the structure structure.

If you name your mappings, you can later load them with that name.

 For<MyInterface>().Add<Class1ForMyInterface>().Named("Class1"); For<MyInterface>().Add<Class2ForMyInterface>().Named("Class2"); 

If you want your Class1ForMyInterface you can call

 container.GetInstance<MyInterface>("Class1"); 

There are also several ways to display all this in your container, and

 For<IController>().Add<Controller1>().Ctor<MyInterface>().Is(i => i.GetInstance<MyInterface>("Class1")); 

Or, if you save the smartinsatance property, which is returned when the type is registered, you can use it in the mapping.

 var class1 = For<MyInterface>().Add<Class1ForMyInterface>().Named("Class1"); For<IController>().Add<Controller1>().Ctor<MyInterface>().Is(class1);
