Definition

在派生类中实现时,运行活动的执行逻辑。When implemented in a derived class, runs the activity's execution logic.

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)

Parameters

context
NativeActivityContext

执行活动的执行上下文。The execution context in which the activity executes.

Examples

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。The following code sample demonstrates using Cancel in a class that inherits from NativeActivity<TResult>. 此示例来自非泛型 ParallelForEach示例。This example is from the Non-Generic ParallelForEach sample.

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();
    }
}
