Açıklamalar

WebPermission , İnternet kaynaklarına erişimi denetlemek için bir dizi yöntem ve özellik sağlar. oluşturulduğunda ayarlanana WebPermission göre PermissionState kaynağınıza kısıtlanmış veya kısıtlanmamış erişim sağlamak için bir WebPermission kullanabilirsiniz.

Aşağıdaki parametre kümelerinden birini kullanarak oluşturucusunu çağırarak bir WebPermission örnek oluşturun:

• Parametre yok. Varsayılan değerdir PermissionStateNone.

• Bir PermissionState. Unrestricted Herhangi bir URI'nin hedef sınıfta kullanılmasına izin vermek veya None yalnızca yöntemini kullanarak AddPermission belirttiğiniz URI'lere erişime izin vermek için belirtin.

• Değer NetworkAccess ve URI dizesi. Belirtilen URI değeri tarafından NetworkAccess verilen izinlere sahip.

• Tanımlayıcı NetworkAccess ve URI normal ifadesi.

ConnectList erişim iznini vermiş olduğunuz URI'leri ve AcceptList tutun. Bu listelerden herhangi birine URI eklemek için kullanın AddPermission. parametresi olarak NetworkAccess geçirirsenizAccept, URI öğesine AcceptListeklenir. WebPermission ile eşleşen URI'lerle hedef sınıfınıza bağlantılara AcceptListizin verir.
