Ejemplos

En el siguiente ejemplo, se muestra cómo utilizar el método AddPackage.

if (rmi.CryptoProvider.CanDecrypt == true)
    ShowStatus("   Decryption granted.");
else
    ShowStatus("   CANNOT DECRYPT!");

ShowStatus("   Getting the Package from\n" +
           "      the EncryptedPackage.");
_xpsPackage = ePackage.GetPackage();
if (_xpsPackage == null)
{
    MessageBox.Show("Unable to get Package.");
    return false;
}

// Set a PackageStore Uri reference for the encrypted stream.
// ("sdk://packLocation" is a pseudo URI used by
//  PackUriHelper.Create to define the parserContext.BaseURI
//  that XamlReader uses to access the encrypted data stream.)
Uri packageUri = new Uri(@"sdk://packLocation", UriKind.Absolute);
// Add the URI package
PackageStore.AddPackage(packageUri, _xpsPackage);
// Determine the starting part for the package.
PackagePart startingPart = GetPackageStartingPart(_xpsPackage);

// Set the DocViewer.Document property.
ShowStatus("   Opening in DocumentViewer.");
ParserContext parserContext = new ParserContext();
parserContext.BaseUri = PackUriHelper.Create(
                            packageUri, startingPart.Uri);
parserContext.XamlTypeMapper = XamlTypeMapper.DefaultMapper;
DocViewer.Document = XamlReader.Load(
    startingPart.GetStream(), parserContext)
        as IDocumentPaginatorSource;

// Enable document menu controls.
menuFileClose.IsEnabled = true;
menuFilePrint.IsEnabled = true;
menuViewIncreaseZoom.IsEnabled = true;
menuViewDecreaseZoom.IsEnabled = true;

// Give the DocumentViewer focus.
DocViewer.Focus();

If rmi.CryptoProvider.CanDecrypt = True Then
    ShowStatus("   Decryption granted.")
Else
    ShowStatus("   CANNOT DECRYPT!")
End If

ShowStatus("   Getting the Package from" & vbLf & "      the EncryptedPackage.")
_xpsPackage = ePackage.GetPackage()
If _xpsPackage Is Nothing Then
    MessageBox.Show("Unable to get Package.")
    Return False
End If

Comentarios

packageUri define el URI de clave del paquete que se compara al llamar a PackWebRequest.

Si coincide packageUri con para Uri en PackagePart una PackWebRequest llamada, el paquete definido en PackageStore se usa para tener acceso al elemento solicitado.

packageUri Si no coincide con para Uri una PackagePart en una PackWebRequest llamada, el paquete con el URI especificado se abre para tener acceso al elemento solicitado.

Nota de seguridad Este método exige EnvironmentPermission todos los tipos personalizados Package (no).ZipPackage
