问题 I'd like to create an instance of a class using unity where the class has two constructors with the same number of parameters. Here is the instantiation: _unityContainer.Resolve<IGradeType>(new ParameterOverride("gradeTypeStringFromXmlFile", gradeTypeStringFromXmlFile)); And here are the constructors: public GradeType(string gradeTypeStringFromXmlFile) { _gradeTypeStringFromXmlFile = gradeTypeStringFromXmlFile; } public GradeType(Enum.GradeType gradeType) { _gradeType = gradeType; } If I try

问题 Microsoft's Unity dependency injection framework can be configured either through code or through the applications configuration file (app.config). Code example: IUnityContainer container = new UnityContainer() .RegisterType<IInterface, ConcreteImplementation>(); Configuration example: <unity> <containers> <container> <types> <type type="IInterface, MyAssembly" mapTo="ConcreteImplementation, MyAssembly" /> What are the advantages/disadvantages to each approach? I can think of the obvious

问题 I'm using Unity and inject all my dependencies. Let's say that I have a Manager class like so public class Manager : IManager { public Manager(IRepository repository, string customerName) { } } And a repository class like: public class Repository : IRepository { public Repository(string customerName) { } } I'm using WCF and will resolve the manager and the repository once per request. I register all my types at service startup, but at startup i do not know the "customerName"-parameter. This

问题 How do I create and populate a Dictionary using Unity's xml configuration? I need to create a Dictionary and populate the objects using dependency references in unity. How can I accomplish this? 回答1: This works <unity xmlns="http://schemas.microsoft.com/practices/2010/unity"> <alias alias="MyStuffObject" type="MyStuffObject, MyStuff"/> <!-- dictionary stuff --> <alias alias="IDictionaryOfStuff" type="System.Collections.Generic.IDictionary`2[[System.String, mscorlib],[MyStuffObject, MyStuff]],

问题 This blog post shows a way to implement auto mocking with Castle Windsor and NSubstitute. I don't know or use Castle Windsor, but I do use Unity and NSubstitute. Is there a way to do what he shows using Unity? Here is relevant content of the post: First of all, register an ILazyComponentLoader into Windsor: var c = new WindsorContainer(); c.Register(Component.For<LazyComponentAutoMocker>()); Then, the implementation of LazyComponentAutoMocker is simply this: public class

问题 I've been at it for days, but I can't get Unity to inject anything with RegisterType<> into my Controller . I'm using Web Api 2, in Visual Studio 2015, with Unity 4. Whenever I try to inject IUnitOfWork or IRFContext , I get "message": "An error occurred when trying to create a controller of type 'ClPlayersController'. Make sure that the controller has a parameterless public constructor." . I'm using the Unity.AspNet.WebApi to bootstrapp into WebApi. Below is my UnityWebApiActivator [assembly

问题 I am trying to do the following and failing: class base {} class derived1 : base {} class derived2 : base {} interface itr<t> where t : class, base {} class c1: itr<derived1> {} class c2 : itr<derived2> {} //The following 2 registrations fail: _unityContainer.RegisterType<itr<base>, c1>("c1"); _unityContainer.RegisterType<itr<base>, c2>("c2"); The error I get is that the second parameter in the above registrations cannot be typecast into the first parameter and this registration is not valid.

问题 Got below code to start with public interface IDataContextAsync : IDataContext { Task<int> SaveChangesAsync(CancellationToken cancellationToken); Task<int> SaveChangesAsync(); } public partial class DB1Context : DataContext{ } public partial class DB2Context : DataContext{ } Below is the UnityConfig file. Note: I am using Nuget bootstrapper for ASP.Net MVC and below is my UnityConfig file public static void RegisterTypes(IUnityContainer container) { container .RegisterType<IDataContextAsync,

问题 I have a MVC application that uses Unity as its IoC container and have multiple services defined in my application using the PerRequestLifetimeManager . container.RegisterType<IFileService, FileService>(); Everything works fine, except when I tried to roll my solution to automate tasks (like SharePoint TimerJobs), started in various intervals. For that, I've defined a ServiceLocator -Type class ContainerManager in a separate project, that does essentially this: public static object Resolve

问题 I'm trying to do the equivalent of the following Autofac code in Unity IoC. builder.RegisterAssemblyTypes(typeof (DataRepository<>).Assembly) .Where(t => t.Name.EndsWith("Repository")) .AsImplementedInterfaces(); This basically replaces individually registering the following: DataSourceDataRepository : DataRepository<DataSource>, IDataSourceDataRepository For clarity: This registers all of my Repository types as their implemented interfaces, so when i inject IDataSourceDataRepository I get a
