Exemplos

O exemplo de código a seguir abre um arquivo de armazenamento isolado, usa-o para gravar informações em um fluxo, fecha o arquivo e usa o Dispose método para liberar todos os recursos.

IsolatedStorageFile^ isoFile;
isoFile = IsolatedStorageFile::GetUserStoreForDomain();

// Open or create a writable file.
IsolatedStorageFileStream^ isoStream = gcnew IsolatedStorageFileStream( this->userName,FileMode::OpenOrCreate,FileAccess::Write,isoFile );
StreamWriter^ writer = gcnew StreamWriter( isoStream );
writer->WriteLine( this->NewsUrl );
writer->WriteLine( this->SportsUrl );

// Calculate the amount of space used to record the user's preferences.
double d = isoFile->CurrentSize / isoFile->MaximumSize;
Console::WriteLine( "CurrentSize = {0}", isoFile->CurrentSize.ToString() );
Console::WriteLine( "MaximumSize = {0}", isoFile->MaximumSize.ToString() );
writer->Close();
isoFile->Close();
isoStream->Close();
return d;

IsolatedStorageFile isoFile;
isoFile = IsolatedStorageFile.GetUserStoreForDomain();

// Open or create a writable file.
IsolatedStorageFileStream isoStream =
    new IsolatedStorageFileStream(this.userName,
    FileMode.OpenOrCreate,
    FileAccess.Write,
    isoFile);

StreamWriter writer = new StreamWriter(isoStream);
writer.WriteLine(this.NewsUrl);
writer.WriteLine(this.SportsUrl);
// Calculate the amount of space used to record the user's preferences.
double d = isoFile.CurrentSize / isoFile.MaximumSize;
Console.WriteLine("CurrentSize = " + isoFile.CurrentSize.ToString());
Console.WriteLine("MaximumSize = " + isoFile.MaximumSize.ToString());
// StreamWriter.Close implicitly closes isoStream.
writer.Close();
isoFile.Dispose();
isoFile.Close();
return d;

Dim isoFile As IsolatedStorageFile
isoFile = IsolatedStorageFile.GetUserStoreForDomain()

' Open or create a writable file.
Dim isoStream As New IsolatedStorageFileStream(Me.userName, FileMode.OpenOrCreate, _
    FileAccess.Write, isoFile)

Dim writer As New StreamWriter(isoStream)
writer.WriteLine(Me.NewsUrl)
writer.WriteLine(Me.SportsUrl)
' Calculate the amount of space used to record the user's preferences.
Dim d As Double = Convert.ToDouble(isoFile.CurrentSize) / Convert.ToDouble(isoFile.MaximumSize)
Console.WriteLine(("CurrentSize = " & isoFile.CurrentSize.ToString()))
Console.WriteLine(("MaximumSize = " & isoFile.MaximumSize.ToString()))
' StreamWriter.Close implicitly closes isoStream.
writer.Close()
isoFile.Dispose()
isoFile.Close()
Return d

Comentários

Chame Dispose quando terminar de usar o IsolatedStorageFile. O Dispose método deixa o IsolatedStorageFile em um estado inutilizável. Depois de chamar Dispose, você deve liberar todas as referências para o IsolatedStorageFile para que o coletor de lixo possa recuperar a memória que IsolatedStorageFile estava ocupando.
