ToolboxComponentsCreatedEventHandler 代理人

部分資訊涉及發行前產品，在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊，不做任何明確或隱含的瑕疵擔保。
代表處理 ComponentsCreated 事件的方法。
public delegate void ToolboxComponentsCreatedEventHandler(System::Object ^ sender, ToolboxComponentsCreatedEventArgs ^ e);public delegate void ToolboxComponentsCreatedEventHandler(object sender, ToolboxComponentsCreatedEventArgs e);type ToolboxComponentsCreatedEventHandler = delegate of obj * ToolboxComponentsCreatedEventArgs -> unitPublic Delegate Sub ToolboxComponentsCreatedEventHandler(sender As Object, e As ToolboxComponentsCreatedEventArgs)- sender
- Object
事件的來源。
下列範例程式代碼提供方法，這個方法會附加 事件的ComponentsCreatedToolboxItem事件處理程式。 它也會提供ToolboxComponentsCreatedEventHandler事件處理程式方法，以寫入事件引發ComponentsCreated事件處理程式時所建立Console元件類型的名稱。
public:
[PermissionSetAttribute(SecurityAction::Demand, Name="FullTrust")]
void LinkToolboxComponentsCreatedEvent( ToolboxItem^ item )
{
item->ComponentsCreated +=
gcnew ToolboxComponentsCreatedEventHandler( this, &Form1::OnComponentsCreated );
}
private:
void OnComponentsCreated( Object^ sender, ToolboxComponentsCreatedEventArgs^ e )
{
// Lists created components on the Console.
for ( int i = 0; i < e->Components->Length; i++ )
{
Console::WriteLine( "Component #" + i + ": " +
e->Components[ i ]->Site->Name );
}
}
public void LinkToolboxComponentsCreatedEvent(ToolboxItem item)
{
item.ComponentsCreated += new ToolboxComponentsCreatedEventHandler(this.OnComponentsCreated);
}
private void OnComponentsCreated(object sender, ToolboxComponentsCreatedEventArgs e)
{
// Lists created components on the Console.
for( int i=0; i< e.Components.Length; i++ )
Console.WriteLine("Component #"+i.ToString()+": "+e.Components[i].Site.Name.ToString());
}
Public Sub LinkToolboxComponentsCreatedEvent(ByVal item As ToolboxItem)
AddHandler item.ComponentsCreated, AddressOf Me.OnComponentsCreated
End Sub
Private Sub OnComponentsCreated(ByVal sender As Object, ByVal e As ToolboxComponentsCreatedEventArgs)
' Lists created components on the Console.
Dim i As Integer
For i = 0 To e.Components.Length - 1
Console.WriteLine(("Component #" + i.ToString() + ": " + e.Components(i).Site.Name.ToString()))
Next i
End Sub
建立 ToolboxComponentsCreatedEventHandler 委派時，必須識別處理事件的方法。 若要使事件與您的事件處理常式產生關聯，請將委派的執行個體 (Instance) 加入至事件。 除非您移除委派，否則每當事件發生時就會呼叫事件處理常式。 如需事件處理程式委派的詳細資訊，請參閱 處理和引發事件。
