Parallel.CompletionCondition 属性

定义

命名空间:

System.Activities.Statements

程序集:

System.Activities.dll

在任何分支完成后计算。

public:
 property System::Activities::Activity<bool> ^ CompletionCondition { System::Activities::Activity<bool> ^ get(); void set(System::Activities::Activity<bool> ^ value); };

[System.Windows.Markup.DependsOn("Variables")]
public System.Activities.Activity<bool> CompletionCondition { get; set; }

[<System.Windows.Markup.DependsOn("Variables")>]
member this.CompletionCondition : System.Activities.Activity<bool> with get, set

Public Property CompletionCondition As Activity(Of Boolean)

属性值

Activity<Boolean>

完成表达式。

属性

DependsOnAttribute

示例

下面的代码示例演示如何设置 Parallel 活动的 CompletionCondition 属性。

return new Parallel
{
    // Timeout from branch causes other branch to cancel.
    CompletionCondition = true,

    Branches =
    {
        // Delay Branch
        new Sequence
        {
            Activities =
            {
                new WriteLine { Text = "Branch1: Body is about to Delay 2secs transferring execution to Branch2" },
                new Delay
                {
                    Duration = TimeSpan.FromSeconds(2)
                },
                new WriteLine { Text = "Branch1: Body is about to complete causing Branch2 to cancel.." },
            }
        },

注解

如果此属性的计算结果为 true，则取消集合中的其他 Branches 计划元素。 如果未设置此属性，则 Activity 集合中的所有 Branches 对象都将执行，直至完成为止。
