代表將處理 ComponentRename 事件的方法。

public delegate void ComponentRenameEventHandler(object sender, ComponentRenameEventArgs e);C#
public delegate void ComponentRenameEventHandler(object? sender, ComponentRenameEventArgs e);C#
[System.Runtime.InteropServices.ComVisible(true)]
public delegate void ComponentRenameEventHandler(object sender, ComponentRenameEventArgs e);type ComponentRenameEventHandler = delegate of obj * ComponentRenameEventArgs -> unit[<System.Runtime.InteropServices.ComVisible(true)>]
type ComponentRenameEventHandler = delegate of obj * ComponentRenameEventArgs -> unitPublic Delegate Sub ComponentRenameEventHandler(sender As Object, e As ComponentRenameEventArgs)- sender
- Object

下列範例示範如何 ComponentRenameEventHandler 註冊 和處理 ComponentRename 事件。
public:
void LinkComponentRenameEvent( IComponentChangeService^ changeService )
{
// Registers an event handler for the ComponentRename event.
changeService->ComponentRename += gcnew ComponentRenameEventHandler(
this, &ComponentRenameEventHandlerExample::OnComponentRename );
}
private:
void OnComponentRename( Object^ /*sender*/, ComponentRenameEventArgs^ e )
{
// Displayss component renamed information on the console.
Console::WriteLine( "Type of the component that has been renamed: " +
e->Component->GetType()->FullName );
Console::WriteLine( "New name of the component that has been renamed: " +
e->NewName );
Console::WriteLine( "Old name of the component that has been renamed: " +
e->OldName );
}
C#
public void LinkComponentRenameEvent(IComponentChangeService changeService)
{
// Registers an event handler for the ComponentRename event.
changeService.ComponentRename += new ComponentRenameEventHandler(this.OnComponentRename);
}
private void OnComponentRename(object sender, ComponentRenameEventArgs e)
{
// Displayss component renamed information on the console.
Console.WriteLine("Type of the component that has been renamed: "+e.Component.GetType().FullName);
Console.WriteLine("New name of the component that has been renamed: "+e.NewName);
Console.WriteLine("Old name of the component that has been renamed: "+e.OldName);
}
Public Sub LinkComponentRenameEvent(ByVal changeService As IComponentChangeService)
' Registers an event handler for the ComponentRename event.
AddHandler changeService.ComponentRename, AddressOf Me.OnComponentRename
End Sub
Private Sub OnComponentRename(ByVal sender As Object, ByVal e As ComponentRenameEventArgs)
' Displays component renamed information on the console.
Console.WriteLine(("Type of the component that has been renamed: " + e.Component.GetType().FullName))
Console.WriteLine(("New name of the component that has been renamed: " + e.NewName))
Console.WriteLine(("Old name of the component that has been renamed: " + e.OldName))
End Sub
建立 ComponentRenameEventHandler 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。
