c# - Autofac:将 OnActivated 添加到所有注册

Question

我需要将 .OnActivated(Initialize) 添加到所有注册中。以下是我现在的做法:

builder.RegisterType<A>()
    .OnActivated(Initialize);

builder.RegisterType<B>()
    .OnActivated(Initialize);

builder.RegisterType<C>()
    .OnActivated(Initialize);

void Initialize(IActivatedEventArgs<object> context)
{
    object obj = context.Instance;
    if (obj is IHasPostConstructor)        
        (obj as IHasPostConstructor).PostConstructor();        
}

如果我能把它简化成类似这样的东西就好了:

builder.RegisterType<A>();
builder.RegisterType<B>();
builder.RegisterType<C>();
builder.AllRegistrations.OnActivated(Initialize);

类似的东西可能吗？

谢谢

您可以像这样创建自己的扩展方法:

public static IRegistrationBuilder<T, ConcreteReflectionActivatorData, SingleRegistrationStyle>  RegisterWithInit<T>(this ContainerBuilder builder)
{
    return builder.RegisterType<T>.OnActivated(Initialize);
}

然后你就可以这样注册了:

builder.RegisterWithInit<A>();
builder.RegisterWithInit<B>();
builder.RegisterWithInit<C>();
