DependencyObject.SetValue(DependencyProperty, Object) DependencyObject.SetValue(DependencyProperty, Object) DependencyObject.SetValue(DependencyProperty, Object) Method

定義

DependencyProperty の値をオブジェクトに設定します。Sets the value of the DependencyProperty to the object.

public:
 void SetValue(System::Workflow::ComponentModel::DependencyProperty ^ dependencyProperty, System::Object ^ value);
public void SetValue (System.Workflow.ComponentModel.DependencyProperty dependencyProperty, object value);
member this.SetValue : System.Workflow.ComponentModel.DependencyProperty * obj -> unit

パラメーター

value
Object Object Object

値が設定される ObjectThe Object to set the value to.

SetValue を使用して、依存関係オブジェクト内で依存関係プロパティを設定する方法を次のコードに示します。The following code shows how a dependency property is set within a dependency object using SetValue.

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)

注釈

SetBinding は依存関係プロパティのバインディングを設定します。SetBinding sets a binding for the dependency property.

SetValue は値を直接 DependencyProperty に設定します (同様に AddHandler は、ハンドラーを直接、イベント型のプロパティに追加します)。SetValue sets a value directly to the DependencyProperty (similarly, AddHandler adds a handler directly to properties of type event).

同じプロパティに対しては、これらのメソッドのどちらか一方しか呼び出すことができません。These methods are exclusive when they are called for the same property. SetBinding を呼び出すと、SetValue (イベント内の AddHandler) を使用して前に設定した値は無視されます。If SetBinding is called, then the values previously set using SetValue (AddHandler in events) are disregarded. 逆の処理にも同じことが当てはまります。つまり、SetValue (AddHandler) を呼び出すと、SetBinding によって割り当てられたバインドがリセットされます。The same is true the other way around: SetValue (AddHandler) resets the binding assigned with SetBinding.
