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PRISM应用程序，我们在其中向下钻取数据(以获取更多详细信息). 在我的实现中，我有一个嵌套的MVVM，当我在树上导航时，我想将模型传递给新创建的视图.

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，当前PRISM允许传递字符串，但不允许传递对象.我想知道解决此问题的方法是什么.

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

我通常使用一种服务，在该服务中注册要与GUID一起传递的对象.这些被存储在哈希表中，当在棱镜中导航时，我将guid作为参数传递给参数，然后可以用来检索对象.

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.
