NativeActivity.Execute(NativeActivityContext) 方法

定义

命名空间:

System.Activities

程序集:

System.Activities.dll

在派生类中实现时，运行活动的执行逻辑。

protected:
 abstract void Execute(System::Activities::NativeActivityContext ^ context);

protected abstract void Execute (System.Activities.NativeActivityContext context);

abstract member Execute : System.Activities.NativeActivityContext -> unit

Protected MustOverride Sub Execute (context As NativeActivityContext)

参数

context

NativeActivityContext

执行活动时所处的执行上下文。

示例

下面的代码示例演示如何在一个从 NativeActivity<TResult> 继承的类中使用 Cancel。 此示例来自 非泛型 ParallelForEach 示例。

protected override void Cancel(NativeActivityContext context)
{
    // If we don't have a completion condition then we can just
    // use default logic.
    if (this.CompletionCondition == null)
    {
        base.Cancel(context);
    }
    else
    {
        context.CancelChildren();
    }
}
