IsolatedStorageFile.GetUserStoreForApplication Method

Obtains user-scoped isolated storage corresponding to the calling code's application identity.

Namespace:  System.IO.IsolatedStorage
Assembly:  mscorlib (in mscorlib.dll)

public static IsolatedStorageFile GetUserStoreForApplication()

Return Value

Type: System.IO.IsolatedStorage.IsolatedStorageFile
An object corresponding to the isolated storage scope based on the calling code's assembly identity.

ExceptionCondition
SecurityException

Sufficient isolated storage permissions have not been granted.

IsolatedStorageException

An isolated storage location cannot be initialized.

-or-

The application identity of the caller cannot be determined, because the ActivationContext property returned null.

-or-

The permissions for the application domain cannot be determined.

All assemblies associated with an application use the same isolated store when using this method. This method can be used only when the application identity can be determined - for example, when the application is published through ClickOnce deployment or is a Silverlight-based application. If you attempt to use this method outside a ClickOnce or Silverlight-based application, you will receive an IsolatedStorageException exception, because the application identity of the caller cannot be determined.

GetUserStoreForApplication is functionally equivalent to the following code:


isoFile = IsolatedStorageFile.GetStore(IsolatedStorageScope.Application |
    IsolatedStorageScope.User, null);


In this code, the applicationIdentity parameter for GetStore(IsolatedStorageScope scope, Object applicationIdentity) is null.
