StructuredCompositeActivityDesigner.CanRemoveActivities 方法

定义

命名空间:

System.Workflow.ComponentModel.Design

程序集:

System.Workflow.ComponentModel.dll

返回一个值，该值指示是否可以从 StructuredCompositeActivityDesigner 中移除指定活动。

public:
 override bool CanRemoveActivities(System::Collections::ObjectModel::ReadOnlyCollection<System::Workflow::ComponentModel::Activity ^> ^ activitiesToRemove);

public override bool CanRemoveActivities (System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> activitiesToRemove);

override this.CanRemoveActivities : System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> -> bool

Public Overrides Function CanRemoveActivities (activitiesToRemove As ReadOnlyCollection(Of Activity)) As Boolean

参数

activitiesToRemove

ReadOnlyCollection<Activity>

包含要移除的活动的 Activity 只读集合。

返回

Boolean

如果可以移除指定活动，则为 true；否则为 false。

示例

下面的示例演示如何重写 CanRemoveActivities 方法，以便允许在 StructuredCompositeActivityDesigner 内移动子活动。

public override bool CanRemoveActivities(ReadOnlyCollection<Activity> activitiesToRemove)
{
    return true;
}

Public Overrides Function CanRemoveActivities(ByVal activitiesToRemove As ReadOnlyCollection(Of Activity)) As Boolean
    Return True
End Function
