Represents the abstract base class from which all isolated storage implementations must derive.

Remarks
Important
Calling methods from this class with untrusted data is a security risk. Call the methods from this class only with trusted data. For more information, see Validate All Inputs.
For information about file-based isolated storage, see the IsolatedStorageFile class.
Important
Isolated storage is not available for Windows 8.x Store apps. Instead, use the application data classes in the Windows.Storage namespaces included in the Windows Runtime API to store local data and files. For more information, see Application data in the Windows Dev Center.
Constructors
| IsolatedStorage() |
Initializes a new instance of the IsolatedStorage class. |
Properties
| ApplicationIdentity |
Gets an application identity that scopes isolated storage. |
| AssemblyIdentity |
Gets an assembly identity used to scope isolated storage. |
| AvailableFreeSpace |
When overridden in a derived class, gets the available free space for isolated storage, in bytes. |
| CurrentSize |
Obsolete.
Obsolete.
Gets a value representing the current size of isolated storage. |
| DomainIdentity |
Gets a domain identity that scopes isolated storage. |
| MaximumSize |
Obsolete.
Obsolete.
Gets a value representing the maximum amount of space available for isolated storage. When overridden in a derived class, this value can take different units of measure. |
| Quota |
When overridden in a derived class, gets a value that represents the maximum amount of space available for isolated storage. |
| Scope |
Gets an IsolatedStorageScope enumeration value specifying the scope used to isolate the store. |
| SeparatorExternal |
Gets a backslash character that can be used in a directory string. When overridden in a derived class, another character might be returned. |
| SeparatorInternal |
Gets a period character that can be used in a directory string. When overridden in a derived class, another character might be returned. |
| UsedSize |
When overridden in a derived class, gets a value that represents the amount of the space used for isolated storage. |
Methods
| CreateObjRef(Type) |
Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject) |
| Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
| GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
| GetLifetimeService() |
Obsolete.
Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject) |
| GetPermission(PermissionSet) |
When implemented by a derived class, returns a permission that represents access to isolated storage from within a permission set. |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| IncreaseQuotaTo(Int64) |
When overridden in a derived class, prompts a user to approve a larger quota size, in bytes, for isolated storage. |
| InitializeLifetimeService() |
Obsolete.
Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject) |
| InitStore(IsolatedStorageScope, Type, Type) |
Initializes a new IsolatedStorage object. |
| InitStore(IsolatedStorageScope, Type) |
Initializes a new IsolatedStorage object. |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| MemberwiseClone(Boolean) |
Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject) |
| Remove() |
When overridden in a derived class, removes the individual isolated store and all contained data. |
| ToString() |
Returns a string that represents the current object. (Inherited from Object) |
