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.
