如何在自定义本机活动中从NativeActivityContext获取对象 [英] How to get the object from the NativeActivityContext in the custom native activity

问题描述

我们用活动设计器创建了一个自定义本机活动，它将安排其他子活动.我们在其上下文中设置了一个名为employee的对象.

We have created a custom native activity with the activity designer.It will schedule other child activities.We have set one object to it's context named employee.

请向我们建议如何在子活动的execute方法中使用NativeActivityContext在子活动中获取/设置此对象.

Please suggest us how can we get/set this object in the child activities using the NativeActivityContext, in the execute method of child activities.

预先感谢

Hi Naga，

Hi Naga,

使用工作流变量在活动之间共享数据.

Use workflow varibales to share data between activities.

尝试在中使用 ActivityBind类 System.Workflow.ComponentModel 命名空间

Try using ActivityBind class in System.Workflow.ComponentModel namespace

ActivityBind 允许数据从工作流中的一个活动流到另一个活动. ActivityBind 是一种声明性的方式，可以完成必须使用代码才能完成的工作，因此是大多数工作流程的关键元素，这些工作流程完全用XAML标记编写.

ActivityBind allows data to flow from one activity to another activity within a workflow. ActivityBind is a declarative way of doing what otherwise must be accomplished using code, and therefore is a key element of most workflows that are written entirely in XAML markup.
