| CacheId |
获取缓存的标识符,该标识符在工作流定义的作用域内是唯一的。Gets the identifier of the cache that is unique within the scope of the workflow definition. (继承自 Activity) |
| CancellationHandler |
在取消时执行的 Activity。The Activity that is executed in the event of cancellation. |
| CanInduceIdle |
获取或设置一个值,该值指示活动是否会使工作流进入空闲状态。Gets or sets a value that indicates whether the activity can cause the workflow to become idle. (继承自 NativeActivity) |
