RegisterType（typeof）vs RegisterType

Question

以下两段代码是否完全相同？

.RegisterType<ICrmService, CrmService>()

和

.RegisterType(typeof(ICrmService), typeof(CrmService))

Answer 1

简而言之：是的，他们确实这样做了。

只需查看源代码：https://unity.codeplex.com/SourceControl/latest#source/Unity/Src/UnityContainerExtensions.cs

通用方法：

public static IUnityContainer RegisterType<TFrom, TTo>(this IUnityContainer container, params InjectionMember[] injectionMembers) where TTo : TFrom
{
    Guard.ArgumentNotNull(container, "container");
    return container.RegisterType(typeof(TFrom), typeof(TTo), null, null, injectionMembers);
}

非通用方法：

public static IUnityContainer RegisterType(this IUnityContainer container, Type from, Type to, params InjectionMember[] injectionMembers)
{
    Guard.ArgumentNotNull(container, "container");
    return container.RegisterType(from, to, null, null, injectionMembers);
}
