Enumerates the levels of isolated storage scope that are supported by IsolatedStorage.

This enumeration supports a bitwise combination of its member values.

Public Enum IsolatedStorageScope

Inheritance: Object

ValueType

Enum
IsolatedStorageScope

Attributes: FlagsAttribute SerializableAttribute ComVisibleAttribute

Fields

None	0	No isolated storage usage.
User	1	Isolated storage scoped by user identity.
Domain	2	Isolated storage scoped to the application domain identity.
Assembly	4	Isolated storage scoped to the identity of the assembly.
Roaming	8	The isolated store can be placed in a location on the file system that might roam (if roaming user data is enabled on the underlying operating system).
Machine	16	Isolated storage scoped to the machine.
Application	32	Isolated storage scoped to the application.

Examples

The following code example demonstrates how the IsolatedStorageScope enumeration is used in the GetStore methods.

// Retrieve an IsolatedStorageFile for the current Domain and Assembly.
IsolatedStorageFile^ isoFile = IsolatedStorageFile::GetStore( static_cast<IsolatedStorageScope>(IsolatedStorageScope::User | IsolatedStorageScope::Assembly | IsolatedStorageScope::Domain), (Type^)nullptr, nullptr );
IsolatedStorageFileStream^ isoStream = gcnew IsolatedStorageFileStream( this->userName,FileMode::Open,FileAccess::ReadWrite,isoFile );


// Retrieve an IsolatedStorageFile for the current Domain and Assembly.
IsolatedStorageFile isoFile =
    IsolatedStorageFile.GetStore(IsolatedStorageScope.User |
    IsolatedStorageScope.Assembly |
    IsolatedStorageScope.Domain,
    null,
    null);

IsolatedStorageFileStream isoStream =
    new IsolatedStorageFileStream("substituteUsername",
    System.IO.FileMode.Open,
    System.IO.FileAccess.Read,
     System.IO.FileShare.Read);

' Retrieve an IsolatedStorageFile for the current Domain and Assembly.
Dim isoFile As IsolatedStorageFile = _
    IsolatedStorageFile.GetStore(IsolatedStorageScope.User _
    Or IsolatedStorageScope.Assembly _
    Or IsolatedStorageScope.Domain, Nothing, Nothing)

Dim isoStream As New IsolatedStorageFileStream("substituteUsername", System.IO.FileMode.Open, _
    System.IO.FileAccess.Read, System.IO.FileShare.Read)

Remarks

Use IsolatedStorageScope to specify a degree of scope for an isolated store. You can specify combinations of these levels that are supported by IsolatedStorage.
