EditingScope EditingScope EditingScope EditingScope Class

定義

編輯範圍,代表 ModelItem 樹狀結構的變更集合,可加以認可或當做工作的原子單元來復原。An editing scope represents a collection of changes to the ModelItem tree that can be committed or rolled back as one atomic unit of work.

public ref class EditingScope : System::Activities::Presentation::Model::ModelEditingScope
public class EditingScope : System.Activities.Presentation.Model.ModelEditingScope
type EditingScope = class
    inherit ModelEditingScope
Public Class EditingScope
Inherits ModelEditingScope
繼承

備註

批次處理針對多個 ModelItem 物件進行的變更集時,這個功能非常有用。This is useful for batching together a set of changes to multiple ModelItem objects. 例如,在傳訊活動中,從引發對話進行的變更會影響多個屬性值。As an example, in the messaging activities, the changes made from the raised dialogs will impact multiple property values. 不過,由於所有變更均來自於引發對話,因此需將變更視為批次變更,並當做單一工作單元來復原。However, as all of the changes come from the raised dialog, the changes need to be considered as a batch and undone as a single unit of work. 如需使用方式的詳細資訊,請參閱「編輯範圍」範例For more details on usage, see the Editing Scope sample
