autofac multiple registrations based on generics type

Question

I have a class that recieves a generic type:

RequestHandler<T>

Now I want to register this class in Autofac multiple times based on the generic type. Something like this:

builder.RegisterType<RequestHandler<Request1>>().As<RequestHandler<T>>();
builder.RegisterType<RequestHandler<Request2>>().As<RequestHandler<T>>();
builder.RegisterType<RequestHandler<Request3>>().As<RequestHandler<T>>();
builder.RegisterType<RequestHandler<Request4>>().As<RequestHandler<T>>();

I know that the syntax is incorrect but I hope you get the idea.

so is this even possible? if so how?

Answer 1

您可以使用RegisterGeneric映射打开的通用类型，如下所示：

builder.RegisterGeneric(typeof(RequestHandler<>)).As(typeof(RequestHandler<>));
