Voorbeelden

In het volgende voorbeeld ziet u hoe u toegang FixedDocumentSequenceReader krijgt tot FixedDocument onderdelen in een XpsDocument.

ShowStatus("   Getting FixedDocumentSequenceReader.");
IXpsFixedDocumentSequenceReader fixedDocSeqReader =
    xpsDocument.FixedDocumentSequenceReader;

ShowStatus("   Getting FixedDocumentReaders.");
ICollection<IXpsFixedDocumentReader> fixedDocuments =
    fixedDocSeqReader.FixedDocuments;

ShowStatus("   Getting FixedPageReaders.");
IEnumerator<IXpsFixedDocumentReader> enumerator =
    fixedDocuments.GetEnumerator();
enumerator.MoveNext();
ICollection<IXpsFixedPageReader> fixedPages =
    enumerator.Current.FixedPages;

// Add a document structure to each fixed page.
int i = 0;
foreach (IXpsFixedPageReader fixedPageReader in fixedPages)
{
    XpsResource pageStructure;
    ShowStatus("   Adding page structure resource:\n       '" +
                       Filename(_fixedPageStructures[i]) + "'");
    try
    {   // Add a new StoryFragment to hold the page structure.
        pageStructure = fixedPageReader.AddStoryFragment();
    }
    catch (System.InvalidOperationException)
    {
        MessageBox.Show(xpsUnstructuredFile +
            "\n\nDocument structure cannot be added.\n\n" +
            Filename(xpsUnstructuredFile) + " might already " +
            "contain an existing document structure.",
            "Cannot Add Document Structure",
            MessageBoxButton.OK, MessageBoxImage.Error);
        break;
    }

    // Copy the page structure to the new StoryFragment.
    WriteResource(pageStructure, _fixedPageStructures[i++]);
}

ShowStatus("   Saving and closing the new document.\n");
xpsDocument.Close();

Opmerkingen

Hoewel deze klasse een enkelvoudige naam gebruikt, kan een XpsDocument set (reeks) van een FixedDocument of meerdere documenten zijn.
