我可以在工厂内创建一个隐式的Lifetime范围吗? [英] Can I create an implicit Lifetime scope within a factory?

问题描述

Autofac是否支持使用工厂的隐式生存期范围?例如，我希望能够执行以下操作

Does Autofac support implicit lifetime scopes for the use of a factory? For example, I would like to be able to do the following

public class Session : IDisposable
{
    public Session(A a, B b, C c)
    {
        ...
    }
} 

...

using (var session = _sessionFactory())
{
    ...
}

然后在每次调用_sessionFactory时，Autofac会自动创建一个嵌套的生存期作用域吗?

and then upon each call to the _sessionFactory have Autofac automatically create a nested lifetime scope?

推荐答案

是.让工厂返回Owned<Session>. 拥有的实例表示调用代码负责处理该服务.实际上，如果您从容器中解析Func<Owned<Session>>，则Autofac会为您提供一个自动工厂来生成此类实例.

Yes. Let the factory return Owned<Session>. Owned instances indicates that the calling code is responsible for disposing the service. Actually, if you resolve a Func<Owned<Session>> from the container, Autofac will give you an automatic factory that produces such instances.
