Cómo: Eliminar almacenes de almacenamiento aislado
IsolatedStorageFile proporciona dos métodos para eliminar archivos de almacenamiento aislado:
El método de instancia Remove, que no toma ningún argumento y elimina el almacén que lo llama. Para esta operación no se requiere ningún permiso. Todo código que pueda tener acceso al almacén puede eliminar los datos que contenga, en parte o en su totalidad.
El método estático Remove, que toma el valor User de IsolatedStorageScope y elimina todos los almacenes del usuario que ejecuta el código. Para realizar esta operación, es necesario el permiso IsolatedStorageFilePermission en el valor AdministerIsolatedStorageByUser de IsolatedStorageContainment.
Ejemplo de DeletingStores
En el siguiente ejemplo de código se muestra el uso del método de instancia y el método estático Remove. La clase obtiene dos almacenes, uno aislado por usuario y ensamblado, y otro aislado por usuario, dominio y ensamblado. El almacén de usuario, dominio y ensamblado se elimina llamando al método Remove del IsolatedStorageFileisoStore1. A continuación, se eliminan todos los demás almacenes del usuario llamando al método estático IsolatedStorageFile.Remove.
