CancellationScope 类

定义

Activity 形式将取消逻辑与执行的主路径相关联(也表示为 Activity)。Associates cancellation logic, in the form of a Activity, with a main path of execution, also expressed as a Activity.

public ref class CancellationScope sealed : System::Activities::NativeActivity
[System.Windows.Markup.ContentProperty("Body")]
public sealed class CancellationScope : System.Activities.NativeActivity
[<System.Windows.Markup.ContentProperty("Body")>]
type CancellationScope = class
    inherit NativeActivity
Public NotInheritable Class CancellationScope
Inherits NativeActivity
继承
CancellationScope
属性

构造函数

CancellationScope()
