  • 參考

定義

命名空間:
System.Activities.Statements
組件:
System.Activities.dll

在任何分支完成時評估。

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)

屬性值

Activity<Boolean>

完成運算式。

屬性
DependsOnAttribute

範例

下列程式碼範例將示範如何設定 Parallel 活動的 CompletionCondition 屬性。

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.." },
            }
        },

備註

如果此屬性評估為 true，則會取消集合中的其他 Branches 排程專案。 如果並未設定此屬性，則 Activity 集合中所有的 Branches 物件會執行到完成為止。
