Examples

The following example shows how to use the AddPackage method.

if (rmi.CryptoProvider.CanDecrypt)
    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

' 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.)
Dim packageUri As New Uri("sdk://packLocation", UriKind.Absolute)
' Add the URI package
PackageStore.AddPackage(packageUri, _xpsPackage)
' Determine the starting part for the package.
Dim startingPart As PackagePart = GetPackageStartingPart(_xpsPackage)

' Set the DocViewer.Document property.
ShowStatus("   Opening in DocumentViewer.")
Dim parserContext As New ParserContext()
parserContext.BaseUri = PackUriHelper.Create(packageUri, startingPart.Uri)
parserContext.XamlTypeMapper = XamlTypeMapper.DefaultMapper
DocViewerProperty.Document = TryCast(XamlReader.Load(startingPart.GetStream(), parserContext), IDocumentPaginatorSource)

' Enable document menu controls.
menuFileClose.IsEnabled = True
menuFilePrint.IsEnabled = True
menuViewIncreaseZoom.IsEnabled = True
menuViewDecreaseZoom.IsEnabled = True

' Give the DocumentViewer focus.
DocViewerProperty.Focus()

Remarks

packageUri defines the package's key URI that is compared when you call PackWebRequest.

If the packageUri matches the Uri for a PackagePart in a PackWebRequest call, the package defined in the PackageStore is used to access the requested part.

If the packageUri does not match the Uri for a PackagePart in a PackWebRequest call, the package with the specified URI is opened to access the requested part.

Security Note This method demands EnvironmentPermission for all custom Package (non-ZipPackage) types.
