在 PRISM 4 中导航到新视图时如何传递对象 [英] How to Pass an object when navigating to a new view in PRISM 4

问题描述

我正在开发一个 PRISM 应用程序，我们在其中深入研究数据(以获取更多详细信息).在我的实现中，我有一个嵌套的 MVVM，当我向下导航树时，我想将模型传递给我新创建的视图.

I am working on a PRISM application where we drill down into the data (to get more details). In my implementation I have a nested MVVM and when I navigate down the tree I would like to pass a model to a my newly created view.

据我所知，目前 PRISM 允许传递字符串，但不允许传递对象.我想知道有什么方法可以解决这个问题.

As far as I know, currently PRISM allows to pass strings, but doesn't allow to pass objects. I would like to know what are the ways of overcoming this issue.

推荐答案

我通常使用一个服务来注册我想要通过 guid 传递的对象.这些存储在哈希表中，当在 prism 中导航时，我将 guid 作为参数传递，然后可用于检索对象.

i usually use a service where i register the objects i want to be passed with a guid. these get stored in a hashtable and when navigating in prism i pass the guid as a parameter which can then be used to retrieve the object.

希望这对你有意义！
