Question

我一直在寻找答案但却找不到答案。我有一个项目使用StructureMap作为它的依赖容器，但现在我想尝试微软的统一。

但是，我无法找到如何将这段代码转换为统一的代码：

ObjectFactory.Initialize(cfg =>
{
    cfg.For<IViewFactory>().Use<DefaultViewFactory>();

    cfg.Scan(scan =>
    {
        scan.TheCallingAssembly();
        scan.ConnectImplementationsToTypesClosing(typeof(IViewBuilder<>));                          scan.ConnectImplementationsToTypesClosing(typeof(IViewBuilder<,>));
    });
});

我知道 cfg.For ... 部分只是调用 container.RegisterType（）; 但是如何进行扫描参与Unity？

Answer 1

查看Unity Auto Registration。还有Nuget package可供使用。

以下是如何使用的示例：

var container = new UnityContainer();

container
     .ConfigureAutoRegistration()
     .ExcludeAssemblies(a => a.GetName().FullName.Contains("Test"))
     .Include(If.Implements<ILogger>, Then.Register().UsingPerCallMode())
         .Include(If.ImplementsITypeName, Then.Register().WithTypeName())
         .Include(If.Implements<ICustomerRepository>, Then.Register().WithName("Sample"))
         .Include(If.Implements<IOrderRepository>,
               Then.Register().AsSingleInterfaceOfType().UsingPerCallMode())
         .Include(If.DecoratedWith<LoggerAttribute>,
               Then.Register()
                      .As<IDisposable>()
                      .WithTypeName()
                      .UsingLifetime<MyLifetimeManager>())
         .Exclude(t => t.Name.Contains("Trace"))
         .ApplyAutoRegistration();

非图书馆方式 - 使用反思

在项目的某个地方（可能在容器注册类中）包含此方法

public static void RegisterImplementationsClosingInterface(UnityContainer container, Assembly assembly, Type genericInterface)
{
    foreach(var type in Assembly.GetExecutingAssembly().GetExportedTypes())
    {
        //   concrete class or not?
        if(!type.IsAbstract && type.IsClass)
        {
            // has the interface or not?
            var iface = type.GetInterfaces()
                .Where(i => i.IsGenericType && i.GetGenericTypeDefinition () 
                    == genericInterface).FirstOrDefault();

            if(iface != null)
            {
                container.RegisterType(iface, type);
            }
        }

    }
}

通话：

RegisterImplementationsClosingInterface(container, Assembly.GetCallingAssembly(), typeof(IViewBuilder<>));

从StructureMap到Unity
