Enumerates the levels of isolated storage scope that are supported by IsolatedStorage.
This enumeration supports a bitwise combination of its member values.

Fields
| Name | Value | Description |
|---|---|---|
| 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.
