我怎样才能解决Funq的IoC循环依赖？ [英] How can I resolve circular dependencies in Funq IoC?

问题描述

我有两个班，我需要互相引用。

I have two classes which I need to reference each other.

class Foo
{
    public Foo(IBar bar) {}
}

class Bar
{
    public Bar(IFoo foo) {}
}

当我做的：

container.RegisterAutoWiredAs<Foo, IFoo>();
container.RegisterAutoWiredAs<Bar, IBar>();

当我尝试解决任何接口，我得到一个圆形的依赖关系图这会导致一个无限循环。有没有一种简单的方法来解决这个在Funq或你知道一种解决方法吗？

and when I try to resolve either interface I get a circular dependency graph which results in an infinite loop. Is there an easy way to solve this in Funq or do you know of a workaround?

推荐答案

您可以随时（在所有集装箱，我会说）依靠懒作为依赖，而不是，这将产生预期的结果。在Funq：

You can always (and in all containers, I'd say) rely on Lazy as a dependency instead, and that would yield the desired result. In Funq:

public Bar(Lazy<IFoo> foo) ...
public Foo(Lazy<IBar> bar) ...

container.Register<IBar>(c => new Bar(c.LazyResolve<IFoo>());
container.Register<IFoo>(c => new Foo(c.LazyResolve<IBar>());
