问题描述

我有一种情况，我需要实例化相同接口的两个不同的实现.

public AutoMapperRegisterFactory(IRegisterAutoMapper registerAutoMapper , IRegisterAutoMapper registerAutoMapperMobile)
{
   m_RegisterAutoMapper = registerAutoMapper;
}

我将如何告诉unity第一个IRegisterAutoMapper应该是类型RegisterAutoMapper和类型RegisterAutoMapperMobile?

的第二个IRegisterAutoMapper

推荐答案

您可以使用多个命名映射进行IREGISTERAUTOMAPPER与IndectionConstructor的多个命名映射，告诉Unity每个参数要使用哪种特定映射.

IUnityContainer container = new UnityContainer()
    .RegisterType<IRegisterAutoMapper, RegisterAutoMapper>() //default
    .RegisterType<IRegisterAutoMapper, MobileRegisterAutoMapper>("Mobile")
    .RegisterType<AutoMapperRegisterFactory>(
        new InjectionConstructor(
            typeof(IRegisterAutoMapper), 
            new ResolvedParameter<IRegisterAutoMapper>("Mobile")));

问题描述

I have a case where I need to instantiate for the same interface two different implementation that are both used in the same class.

public AutoMapperRegisterFactory(IRegisterAutoMapper registerAutoMapper , IRegisterAutoMapper registerAutoMapperMobile)
{
   m_RegisterAutoMapper = registerAutoMapper;
}

How would I go about of telling unity that the first IRegisterAutoMapper should be of type RegisterAutoMapper and the second of type RegisterAutoMapperMobile ?

推荐答案

You can do it with multiple named mappings for IRegisterAutoMapper combined with an InjectionConstructor telling Unity what specific mappings to use for each argument.

IUnityContainer container = new UnityContainer()
    .RegisterType<IRegisterAutoMapper, RegisterAutoMapper>() //default
    .RegisterType<IRegisterAutoMapper, MobileRegisterAutoMapper>("Mobile")
    .RegisterType<AutoMapperRegisterFactory>(
        new InjectionConstructor(
            typeof(IRegisterAutoMapper), 
            new ResolvedParameter<IRegisterAutoMapper>("Mobile")));
