備註

SPEventReceiverBase類別應該不要作初始化，但提供接收器類別衍生自它繼承階層架構章節中所列的方法。覆寫其中一個衍生類別下面建立自訂事件處理常式，並使用SPEventReceiverDefinition類別註冊處理常式。

Examples

下列程式碼範例示範如何註冊設陷在網站上的 delete 事件的自訂事件接收器。

Dim webSite As SPWeb = New SPSite("https://localhost").OpenWeb()
Dim newReceiver As SPEventReceiverDefinition = webSite.EventReceivers.Add()
newReceiver.Class = "Receiver.Class1"
newReceiver.Assembly = "Receiver, Version=1.0.0.0, Culture=neutral, PublicKeyToken =10b23036c9b36d6d"
newReceiver.SequenceNumber = 3000
newReceiver.Type = SPEventReceiverType.SiteDeleting
newReceiver.Update()

SPWeb oWebsite = new SPSite("https://localhost").OpenWeb();
SPEventReceiverDefinition newReceiver = oWebsite.EventReceivers.Add();
newReceiver.Class = "Receiver.Class1";
newReceiver.Assembly = "Receiver, Version=1.0.0.0, Culture=neutral, PublicKeyToken =10b23036c9b36d6d";
newReceiver.SequenceNumber = 3000;
newReceiver.Type = SPEventReceiverType.SiteDeleting;
newReceiver.Update();
oWebsite.Dispose();

注意事項
某些物件實作IDisposable介面，並且您必須避免之後不再需要保留這些物件在記憶體中。良好的程式碼撰寫方式的相關資訊，請參閱Disposing Objects。
