備註

SPEventPropertiesBase類別不會具現化，但提供從它衍生的類別繼承階層架構章節中所列的方法。

Examples

下列範例的事件處理常式方法會覆寫**ItemDeleting()**方法，並使用SPEventPropertiesBase類別的繼承的屬性取消事件，並顯示錯誤訊息。

public override void ItemDeleting(SPItemEventProperties properties)
{
    properties.Status = SPEventReceiverStatus.CancelWithError;
    properties.ErrorMessage = "Deleting items is not supported.";
}

Public Overrides Sub ItemDeleting(ByVal properties As SPItemEventProperties)
    properties.Status = SPEventReceiverStatus.CancelWithError
    properties.ErrorMessage = "Deleting items is not supported."
End Sub

Thread safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
