將 DependencyProperty 的值設定給物件。
public:
void SetValue(System::Workflow::ComponentModel::DependencyProperty ^ dependencyProperty, System::Object ^ value);C#
public void SetValue (System.Workflow.ComponentModel.DependencyProperty dependencyProperty, object value);member this.SetValue : System.Workflow.ComponentModel.DependencyProperty * obj -> unitPublic Sub SetValue (dependencyProperty As DependencyProperty, value As Object)- dependencyProperty
- DependencyProperty
要設定的 DependencyProperty。
下列程式碼顯示如何使用 SetValue 在相依性物件內設定相依性屬性。
C#
System.Workflow.ComponentModel.ActivityBind activityBind1 = new System.Workflow.ComponentModel.ActivityBind();
this.SampleReplicatorChildActivity1 = new SampleReplicatorChildActivity();
this.ReplicatorWork = new System.Workflow.Activities.ReplicatorActivity();
//
// SampleReplicatorChildActivity1
//
this.SampleReplicatorChildActivity1.InstanceData = null;
this.SampleReplicatorChildActivity1.Name = "SampleReplicatorChildActivity1";
activityBind1.Name = "SimpleReplicatorWorkflow";
activityBind1.Path = "ChildData";
//
// ReplicatorWork
//
this.ReplicatorWork.Activities.Add(this.SampleReplicatorChildActivity1);
this.ReplicatorWork.ExecutionType = System.Workflow.Activities.ExecutionType.Sequence;
this.ReplicatorWork.Name = "ReplicatorWork";
this.ReplicatorWork.ChildInitialized += new System.EventHandler<System.Workflow.Activities.ReplicatorChildEventArgs>(this.ChildInitializer);
this.ReplicatorWork.SetBinding(System.Workflow.Activities.ReplicatorActivity.InitialChildDataProperty, ((System.Workflow.ComponentModel.ActivityBind)(activityBind1)));
Dim activityBind1 As New System.Workflow.ComponentModel.ActivityBind()
Me.SampleReplicatorChildActivity1 = New SampleReplicatorChildActivity()
Me.ReplicatorWork = New System.Workflow.Activities.ReplicatorActivity()
'
' SampleReplicatorChildActivity1
'
Me.SampleReplicatorChildActivity1.InstanceData = Nothing
Me.SampleReplicatorChildActivity1.Name = "SampleReplicatorChildActivity1"
activityBind1.Name = "SimpleReplicatorWorkflow"
activityBind1.Path = "ChildData"
'
' ReplicatorWork
'
Me.ReplicatorWork.Activities.Add(Me.SampleReplicatorChildActivity1)
Me.ReplicatorWork.ExecutionType = System.Workflow.Activities.ExecutionType.Sequence
Me.ReplicatorWork.Name = "ReplicatorWork"
AddHandler Me.ReplicatorWork.ChildInitialized, AddressOf Me.ChildInitializer
Me.ReplicatorWork.SetBinding(System.Workflow.Activities.ReplicatorActivity.InitialChildDataProperty, activityBind1)
SetBinding 設定相依性屬性的繫結。
SetValue 會直接將值設定為 DependencyProperty (同樣地，AddHandler 會將處理常式直接加入至型別事件的屬性)。
這些方法在呼叫相同屬性時是互斥的。 如果呼叫 SetBinding，則先前使用 SetValue (在事件中的 AddHandler) 設定的值會被忽略。 反之亦相同：SetValue (AddHandler) 會重設使用 SetBinding 指派的繫結程序。
