GetStore(IsolatedStorageScope, Object)
- Source:
- IsolatedStorageFile.cs

- Source:
- IsolatedStorageFile.cs
Obtains isolated storage corresponding to the given application identity.
public:
static System::IO::IsolatedStorage::IsolatedStorageFile ^ GetStore(System::IO::IsolatedStorage::IsolatedStorageScope scope, System::Object ^ applicationIdentity);
public static System.IO.IsolatedStorage.IsolatedStorageFile GetStore (System.IO.IsolatedStorage.IsolatedStorageScope scope, object? applicationIdentity);
public static System.IO.IsolatedStorage.IsolatedStorageFile GetStore (System.IO.IsolatedStorage.IsolatedStorageScope scope, object applicationIdentity);
static member GetStore : System.IO.IsolatedStorage.IsolatedStorageScope * obj -> System.IO.IsolatedStorage.IsolatedStorageFile
Public Shared Function GetStore (scope As IsolatedStorageScope, applicationIdentity As Object) As IsolatedStorageFile
Parameters
- scope
- IsolatedStorageScope
A bitwise combination of the enumeration values.
- applicationIdentity
- Object
An object that contains evidence for the application identity.
Returns
An object that represents the parameters.
Exceptions
Sufficient isolated storage permissions have not been granted.
The applicationIdentity
identity has not been passed in.
The scope
is invalid.
An isolated storage location cannot be initialized.
-or-
scope
contains the enumeration value Application, but the application identity of the caller cannot be determined,because the ActivationContext for the current application domain returned null
.
-or-
scope
contains the value Domain, but the permissions for the application domain cannot be determined.
-or-
scope
contains the value Assembly, but the permissions for the calling assembly cannot be determined.
Remarks
Note
If the scope
parameter is IsolatedStorageScope.Application and the application domain in which the assembly is installed does not have IsolatedStorageFilePermission, the GetStore method will return an IsolatedStorageFile object without a quota. Later attempts to create an IsolatedStorageFile object using the IsolatedStorageFile object that does not have a quota will fail with an IsolatedStorageException.

scope
contains the value Domain, but the permissions for the application domain cannot be determined.
-or-
scope
contains the value Assembly, but the permissions for the calling assembly cannot be determined.
Remarks
Note
If the scope
parameter is Application and the application domain in which the assembly is installed does not have IsolatedStorageFilePermission, the GetStore method will return an IsolatedStorageFile object without a quota.

GetStore(IsolatedStorageScope, Object, Object)
- Source:

- Source:

- Source:
- IsolatedStorageFile.cs
Obtains the isolated storage corresponding to the given application domain and assembly evidence objects.
public:
static System::IO::IsolatedStorage::IsolatedStorageFile ^ GetStore(System::IO::IsolatedStorage::IsolatedStorageScope scope, System::Object ^ domainIdentity, System::Object ^ assemblyIdentity);
public static System.IO.IsolatedStorage.IsolatedStorageFile GetStore (System.IO.IsolatedStorage.IsolatedStorageScope scope, object? domainIdentity, object? assemblyIdentity);
public static System.IO.IsolatedStorage.IsolatedStorageFile GetStore (System.IO.IsolatedStorage.IsolatedStorageScope scope, object domainIdentity, object assemblyIdentity);
static member GetStore : System.IO.IsolatedStorage.IsolatedStorageScope * obj * obj -> System.IO.IsolatedStorage.IsolatedStorageFile
Public Shared Function GetStore (scope As IsolatedStorageScope, domainIdentity As Object, assemblyIdentity As Object) As IsolatedStorageFile
Parameters
- scope
- IsolatedStorageScope
A bitwise combination of the enumeration values.
- domainIdentity
- Object
An object that contains evidence for the application domain identity.
- assemblyIdentity
- Object
An object that contains evidence for the code assembly identity.
Returns
An object that represents the parameters.
Exceptions
Sufficient isolated storage permissions have not been granted.
Neither domainIdentity
nor assemblyIdentity
has been passed in. This verifies that the correct constructor is being used.
-or-
Either domainIdentity
or assemblyIdentity
is null
.
The scope
is invalid.
An isolated storage location cannot be initialized.
-or-
scope
contains the enumeration value Application, but the application identity of the caller cannot be determined, because the ActivationContext for the current application domain returned null
.
-or-
scope
contains the value Domain, but the permissions for the application domain cannot be determined.
-or-
scope
contains the value Assembly, but the permissions for the calling assembly cannot be determined.
Remarks
This form of GetStore
is most useful for administrative code that needs to open a store as if it were another assembly. The store is opened for the evidence provided and not for the currently executing assembly.
Note
If the scope
parameter is Domain and the application domain in which the assembly is installed does not have IsolatedStorageFilePermission, the GetStore method will return an IsolatedStorageFile object without a quota. Later attempts to create an IsolatedStorageFile object using the IsolatedStorageFile object that does not have a quota will fail with an IsolatedStorageException.

Parameters
- scope
- IsolatedStorageScope
A bitwise combination of the enumeration values.
- domainEvidenceType
- Type
The type of the Evidence that you can chose from the list of Evidence present in the domain of the calling application. null
lets the IsolatedStorage object choose the evidence.
- assemblyEvidenceType
- Type
The type of the Evidence that you can chose from the list of Evidence present in the domain of the calling application. null
lets the IsolatedStorage object choose the evidence.
Returns
An object that represents the parameters.
Exceptions
Sufficient isolated storage permissions have not been granted.
The scope
is invalid.
The evidence type provided is missing in the assembly evidence list.
-or-
An isolated storage location cannot be initialized.
-or-
scope
contains the enumeration value Application, but the application identity of the caller cannot be determined, because the ActivationContext for the current application domain returned null
.
-or-
scope
contains the value Domain, but the permissions for the application domain cannot be determined.
-or-
scope
contains Assembly, but the permissions for the calling assembly cannot be determined.
Examples
The following code example demonstrates the GetStore method. For the complete context of this example, see the IsolatedStorageFile overview.
// 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
This is the overload of GetStore most likely to be called from application code.
This overload of GetStore opens an isolated store for the evidence types that are passed in.
Note
If the scope
parameter is Domain and the application domain in which the assembly is installed does not have IsolatedStorageFilePermission, the GetStore method will return an IsolatedStorageFile object without a quota. Later attempts to create an IsolatedStorageFile object using the IsolatedStorageFile object that does not have a quota will fail with an IsolatedStorageException.

Remarks
Note
If the scope
