StructureMap container with constructor parameters

I have a class, RepositoryManager, and I am using this class in some of my controllers:

public RepositoryManager
{
    public IGenericRepository Repository {get; set;}

    public RepositoryManager()
    {
        Repository = new GenericRepository(new MyEntities());
    }

    //...
}

I want to move IGenericRepository to a StructureMap Inversion of control (IoC) container

x.For<IGenericRepository>().Use<GenericRepository>().Ctor<MyEntities>("MyEntities");

Then I change my class constructor to that:

public RepositoryManager(IGenericRepository repository)
{
    Repository = repository;
}

But the injection didn't work. I also tried to use the [SetterProperty] attribute on Repository, but still Repository didn't instantiate.

What did I do wrong?

My complete IoC initialization:

publi开发者_StackOverflow社区c static class IoC {
    public static IContainer Initialize() {
        ObjectFactory.Initialize(x =>
            {
                x.Scan(scan =>
                    {
                        scan.TheCallingAssembly();
                        scan.WithDefaultConventions();
                    });
                x.For<IRepositoryManager>().Use<RepositoryManager>();
                x.For<IGenericRepository>().Use<GenericRepository>().Ctor<MyEntities>("MyEntities");
            });
        return ObjectFactory.Container;
    }
}

Basically your IoC initialisation is wrong for IGenericRepository. Change it to:

x.For<IGenericRepository>().Use(() => new GenericRepository(new MyEntities()));

In such a case, the constructor with parameter MyEntities will be called and an instance of MyEntities will be created and passed to that constructor as a parameter.

You do not need to register the concrete types; they will just be resolved by StructureMap. The scanner is already used with default conventions, so for the above example the following registration code is fully sufficient:

    ObjectFactory.Initialize(x => x.Scan(scanner =>
    {
        scanner.TheCallingAssembly();
        scanner.WithDefaultConventions();
    }));
