问题描述
这是我的情况：
我有这样的应用程序：
我使用Ninject作为我的DI容器，我与WPF 的
1，有 ClassB的被注入 ClassA的它被喷成 1stViewModel 被注入 1stView
1-There is ClassB which is injected into ClassA Which is Injected into 1stViewModel which is injected into 1stView
2 - 同样有 ClassR 被注入 ClassQ 至极注入 2ndViewModel 被注入 2ndView
2- Again There is ClassR which is injected into ClassQ Wich is Injected into 2ndViewModel which is injected into 2ndView
3，而出现这种情况的第3和第4个窗口
3-And this happens for the 3rd and 4th window
问题：
1 - 我能做些什么来解决各阶级在需要的时候（当用户点击第一个按钮或2日）不在我的作文的根？
1- What can I do to Resolve the Classes when they are needed (when user clicks on 1st Button or 2nd) not in my composition root?
2 - 如果我不注入我的的ViewModels 进入我的意见，我希望可以对新实例我的视图模型里面我看来，这显然需要一个参数，即 IClassA 为第1和 IClassQ 进行第2次例如。我该怎么办呢？
2- If I don't Inject my ViewModels into my Views and I want to make new instance of my ViewModel inside my View, obviously it needs a parameter which is IClassA for the 1st and IClassQ for the 2nd for example. How can I do it?
推荐答案
使用ninject.extensions.factory与您可以定义或给定的接口定义 ToFactory 绑定在构造函数;你可以注入一个延迟＆LT; T＆GT。更多详情请看这里 https://github.com/ninject/ninject扩展的维基。 extensions.factory /维基
Use ninject.extensions.factory with that you can define ToFactory bindings for a given interface you define or you can inject a Lazy<T> in your constructor. More details see the wiki of the extension here https://github.com/ninject/ninject.extensions.factory/wiki
