ConnectionPoint.InterfaceType Properti

Definisi

Mendapatkan jenis antarmuka yang digunakan oleh titik koneksi.

public:
 property Type ^ InterfaceType { Type ^ get(); };
public Type InterfaceType { get; }
member this.InterfaceType : Type
Public ReadOnly Property InterfaceType As Type

Nilai Properti

Type yang sesuai dengan jenis antarmuka yang disediakan atau dikonsumsi oleh kontrol.

Contoh

Contoh kode berikut menunjukkan penggunaan InterfaceType properti pada objek ProviderConnectionPoint dan ConsumerConnectionPoint . Contoh kode ini hanya memperlihatkan halaman Web yang berisi kode untuk mengakses properti; untuk kode lengkap yang diperlukan untuk menjalankan contoh, lihat bagian Contoh dari ConnectionPoint gambaran umum kelas.

Kode dalam Button2_Click metode halaman Web mengakses InterfaceType properti pada setiap objek titik koneksi dan menulis setiap nilai ke label. Jalankan kode dengan mengklik tombol Detail Titik Koneksi setelah halaman dimuat di browser.

Keterangan

Properti InterfaceType menunjukkan jenis antarmuka apa yang digunakan titik koneksi. Ini dapat membantu menentukan apakah dua kontrol kompatibel dan dapat membentuk koneksi. Jika titik InterfaceType koneksi penyedia berbeda dari titik InterfaceTypekoneksi konsumen , maka kedua kontrol tidak kompatibel (artinya tidak dapat terhubung langsung tanpa transformator), dan WebPartTransformer objek harus digunakan untuk membuat koneksi.
