Örnekler

Aşağıdaki kod örneği, hem ConsumerConnectionPoint hem de ProviderConnectionPoint nesnelerinde özelliğinin InterfaceType kullanımını gösterir. Bu kod örneği yalnızca özelliğine erişecek kodu içeren Web sayfasını gösterir; örneği çalıştırmak için gereken kodun tamamı için, sınıfa genel bakışın ConnectionPoint Örnek bölümüne bakın.

Web sayfasının yöntemindeki Button2_Click kod, bağlantı noktası nesnelerinin InterfaceType her birinde özelliğine erişir ve her değeri bir etikete yazar. Sayfa bir tarayıcıya yüklendikten sonra Bağlantı Noktası Ayrıntıları düğmesine tıklayarak kodu yürütebilirsiniz.

Açıklamalar

özelliği, InterfaceType bir bağlantı noktasının kullandığı arabirim türünü gösterir. Bu, iki denetimin uyumlu olup olmadığını ve bağlantı oluşturup oluşturamadığını belirlemeye yardımcı olabilir. Sağlayıcı bağlantı noktasının değeri tüketici bağlantı noktasının InterfaceType InterfaceTypeöğesinden farklıysa, iki denetim uyumsuzdur (başka bir deyişle transformatör olmadan doğrudan bağlanamazlar) ve bağlantı kurmak için bir WebPartTransformer nesne kullanılmalıdır.
