Dependency Injection of Multiple Objects Same Interface using StructureMap
I have been reading Mark Seemann's excellent book on Dependency Injection & applying what I have been learning to StructureMap.
Often times I have multiple objects that implement the same interface. In the past I may have used an abstract factory to create the instance I needed at a given time based on some sort of key or identifier like so:
However I was interested in using an IOC container like StructureMap to get rid of the ugly switch statement with the factory object. I did so by registering each object in my container and giving it a name with the .Named() method like so:
If you would like to see more please check out a simple example project over at my GitHub called MultipleObjectDemo.
