    Panel1.Controls.AddRange(New Control() {RadioAddButton, RadioAddRangeButton})
End Sub

Keterangan

Objek Control yang terkandung dalam controls array ditambahkan ke akhir koleksi.

Anda dapat menggunakan AddRange metode untuk menambahkan sekelompok Control objek dengan cepat ke koleksi alih-alih menambahkan masing-masing Control secara manual ke koleksi menggunakan Add metode .

Untuk menghapus Control yang sebelumnya Anda tambahkan, gunakan Removemetode , RemoveAt, atau Clear .

Catatan Bagi Inheritor

Saat mengambil alih kelas turunan AddRange(Control[]) , pastikan untuk memanggil metode kelas AddRange(Control[]) dasar untuk memastikan bahwa kontrol ditambahkan ke koleksi.
