Aşağıdaki kod örneği bir kayıt defteri anahtarı oluşturur ve kayıt defteri veri türlerini belirtmek için kullanarak RegistryValueKind bu anahtar için çeşitli değerler ayarlar. Daha sonra örnek, değerleri almak ve görüntülemek için kayıt defteri veri türlerini denetlemek için kullanır RegistryKey.GetValueKind .

Açıklamalar

Numaralandırma, RegistryValueKind desteklenen kayıt defteri veri türleri kümesini ve desteklenmeyen türler için kullanılan değeri (Bilinmiyor) tanımlar. .NET Framework 4'te başlayarak, Yok değeriyle bir veri türü kullanmamayı belirtebilirsiniz.

RegistryKey.GetValueKind Değerini almadan önce bir kayıt defteri anahtarı değerinin veri türünü belirlemek için yöntemini kullanın. Bir kayıt defteri anahtarı değeri ayarladığınızda SetValue , kayıt defteri veri türünü açıkça belirtmek için yöntemini kullanın.
