Delete an Object
Ejemplo
The following code shows how to delete one object from its realm:
realm.Write(() => { // Remove the instance from the realm. realm.Remove(dog); // Discard the reference. dog = null; });
Delete Multiple Objects
Ejemplo
The following code demonstrates how to delete a collection from a realm:
realm.Write(() => { // Find dogs younger than 2 years old. var puppies = realm.All<Dog>().Where(dog => dog.Age < 2); // Remove the collection from the realm. realm.RemoveRange(puppies); });
Delete an Object and its Dependent Objects
Sometimes, you have dependent objects that you want to delete when you delete the parent object. We call this a chaining delete. Realm will not delete the dependent objects for you. If you do not delete the objects yourself, they will remain orphaned in your realm. Whether or not this is a problem depends on your application's needs.
Currently, the best way to delete dependent objects is to iterate through the dependencies and delete them before deleting the parent object.
Ejemplo
The following code demonstrates how to perform a chaining delete by first deleting all of Ali's dogs, then deleting Ali:
realm.Write(() => { // Remove all of Ali's dogs. realm.RemoveRange(ali.Dogs); // Remove Ali. realm.Remove(ali); });
Delete All Object of a Specific Type
Realm permite borrar todas las instancias de un tipo Realm de un realm.
Ejemplo
The following code demonstrates how to delete all Dog instances from a realm:
realm.Write(() => { // Remove all instances of Dog from the realm. realm.RemoveAll<Dog>(); });
Delete All Objects in a Realm
Es posible borrar todos los objetos del realm. Esto no afecta el esquema del realm. Esto es útil para limpiar rápidamente tu realm mientras creas prototipos.
Ejemplo
The following code demonstrates how to delete everything from a realm:
realm.Write(() => { // Remove all objects from the realm. realm.RemoveAll(); });
