IsolatedStorageScope Enumeration

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

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

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

Syntax

Visual Basic (Declaration)

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
<FlagsAttribute> _
Public Enumeration IsolatedStorageScope

Visual Basic (Usage)

Dim instance As IsolatedStorageScope

[SerializableAttribute]
[ComVisibleAttribute(true)]
[FlagsAttribute]
public enum IsolatedStorageScope

Visual C++

[SerializableAttribute]
[ComVisibleAttribute(true)]
[FlagsAttribute]
public enum class IsolatedStorageScope

JScript

public enum IsolatedStorageScope

Members

	Member name	Description
	None	No isolated storage usage.
	User	Isolated storage scoped by user identity.
	Domain	Isolated storage scoped to the application domain identity.
	Assembly	Isolated storage scoped to the identity of the assembly.
	Roaming	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	Isolated storage scoped to the machine.
	Application	Isolated storage scoped to the application.

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.

Examples

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

Visual Basic

' 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(Me.userName, FileMode.Open, _
    FileAccess.Read, FileShare.Read)

// 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(this.userName,
    FileMode.Open,
    FileAccess.Read,
    FileShare.Read);

Visual C++

// 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 );
