Question

我的代码如下

IUnityContainer container = new UnityContainer(); 

container
.ConfigureAutoRegistration()
.LoadAssemblyFrom(typeof(Test).Assembly.Location)
.LoadAssemblyFrom(typeof(ITest).Assembly.Location)
.ApplyAutoRegistration();

这是我的第一个问题。

我不确定我是否在这里正确使用了LoadAssemblyFrom方法：

ITest test = container.Resolve<ITest>();

当我尝试编译时，我得到异常“ResolutionFailedException”。

我做错了什么？

感谢您的提前时间。

Answer 1

看来你正在寻找的是：

container.ConfigureAutoRegistration()
         .LoadAssemblyFrom(typeof(ITest).Assembly.Location)
         .LoadAssemblyFrom(typeof(Test).Assembly.Location)
         .Include(If.ImplementsITypeName, Then.Register())
         .ApplyAutoRegistration();

这将告诉Unity.AutoRegistration注册所有类型的接口，前缀为I。

这是一个完整的工作控制台示例，显示如何按惯例设置Unity以进行注册，然后将控制转移到依赖注入世界。为此，您必须添加Unity NuGet包。

使用Unity v3.5和VS 2012进行测试。

            using (var container = new UnityContainer())
            {
                // Manual method.
                //container.RegisterType<IEntryPoint, EntryPoint>();
                //container.RegisterType<IInjected, Injected>();

                container.RegisterTypes(

                    WithMappings.FromMatchingInterface,
                    WithName.Default,
                    WithLifetime.ContainerControlled);

                var controller = container.Resolve<IEntryPoint>();
                controller.Main();
            }
        }
    }

    public interface IEntryPoint
    {
        string Name { get; set; }
        void Main();
    }

    public class EntryPoint : IEntryPoint
    {
        private readonly IInjected Injected;

        public EntryPoint(IInjected injected)
        {
            Injected = injected;
        }

        public void Main()
        {

            Injected.SubMain();
            Injected2.SubMain();
            Console.Write("[any key to continue]");
            Console.ReadKey();
        }

        // Demonstrates property injection.
        [Dependency]
        public IInjected Injected2 { get; set; }

        public string Name { get; set; }

    public interface IInjected
