为通用接口和类对指定默认的Unity类型映射 [英] Specifying a default Unity type mapping for a generic interface and class pair

问题描述

我们正在使用基于构造函数的依赖注入， AutoMapper 和 Unity 代码库。

We're using constructor-based dependency injection, AutoMapper and Unity on a codebase.

我们用一个通用接口封装了AutoMapper .. 。

We have wrapped AutoMapper with a generic interface...

public interface IMapper<TSource, TDestination>
{
    TDestination Map(TSource source);
}

一个实现这个界面的类...

And a class that implements this interface...

public class AutomaticMapper<TSource, TDestination> : IMapper<TSource, TDestination>
{
    public TDestination Map(TSource source)
    {
        return AutoMapper.Mapper.Map<TSource, TDestination>(source);
    }
}

这个效果很好，但这意味着对于每个映射我们在AutoMapper配置中定义，我们需要执行一个额外的 UnityContainer.RegisterType 。

This works well, but it means that for every mapping we define in the AutoMapper configuration we need to perform an additional UnityContainer.RegisterType.

这些类型的映射几乎总是的形式

These type mappings are almost always of the form

container.RegisterType<IMapper<ClassA, ClassB>, AutomaticMapper<ClassA, ClassB>>();

有什么办法可以让团队使用从<$ c映射的默认类型映射$ c> IMapper to AutomaticMapper 使用相同的 TSource 和

Is there any way that we can tell unity to use a default type mapping that maps from IMapper to AutomaticMapper using the same TSource and TDestination for each of them?

推荐答案

我们实际上做的几乎相同。在Unity中，您可以说：

We actually do almost the same exact thing. In Unity, you can say:

unityContainer.RegisterType(typeof(IMapper<,>), typeof(AutomaticMapper<,>));
