IsolatedStorageFile.Dispose-Methode

Gibt sämtliche vom IsolatedStorageFile verwendeten Ressourcen frei.

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

Syntax

'Declaration
Public Sub Dispose
'Usage
Dim instance As IsolatedStorageFile

instance.Dispose

public void Dispose ()

public:
virtual void Dispose () sealed

public final void Dispose ()

public final function Dispose ()

Hinweise

Rufen Sie Dispose auf, wenn Sie das IsolatedStorageFile nicht mehr benötigen. Die Dispose-Methode bewirkt, dass der IsolatedStorageFile nicht mehr verwendet werden kann. Nach dem Aufruf von Dispose müssen Sie alle Verweise auf IsolatedStorageFile freigeben, sodass der von der IsolatedStorageFile belegte Speicher bei der Garbage Collection wieder zugänglich gemacht werden kann.

Beispiel

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

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;

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;
