Beispiele

Im folgenden Beispiel wird die Verwendung der Save-Methode gezeigt.

// This method accepts an input stream and a corresponding data format.  The method
// will attempt to load the input stream into a TextRange selection, apply Bold formatting
// to the selection, save the reformatted selection to an alternat stream, and return 
// the reformatted stream.  
Stream BoldFormatStream(Stream inputStream, string dataFormat)
{
    // A text container to read the stream into.
    FlowDocument workDoc = new FlowDocument();
    TextRange selection = new TextRange(workDoc.ContentStart, workDoc.ContentEnd);
    Stream outputStream = new MemoryStream();

    try
    {
        // Check for a valid data format, and then attempt to load the input stream
        // into the current selection.  Note that CanLoad ONLY checks whether dataFormat
        // is a currently supported data format for loading a TextRange.  It does not 
        // verify that the stream actually contains the specified format.  An exception 
        // may be raised when there is a mismatch between the specified data format and 
        // the data in the stream. 
        if (selection.CanLoad(dataFormat))
            selection.Load(inputStream, dataFormat);
    }
    catch (Exception e) { return outputStream; /* Load failure; return a null stream. */ }

    // Apply Bold formatting to the selection, if it is not empty.
    if (!selection.IsEmpty)
        selection.ApplyPropertyValue(TextElement.FontWeightProperty, FontWeights.Bold);

    // Save the formatted selection to a stream, and return the stream.
    if (selection.CanSave(dataFormat))
        selection.Save(outputStream, dataFormat);

    return outputStream;
}

Hinweise

Wenn diese Methode zurückgegeben wird, stream bleibt sie geöffnet, und die aktuelle Position innerhalb stream ist nicht definiert.

Im Rahmen des Speichervorgangs können Inhalte in der aktuellen Auswahl in das durch dataFormatdie Datei angegebene Datenformat konvertiert werden.

Hinweise

Wenn preserveTextElements dies der Typ ist false, werden benutzerdefinierte TextElement Objekte als bekannte TextElement Typen gespeichert. Angenommen, Sie erstellen einen benutzerdefinierten TextElement Namen Heading1, der von Paragraph. Wenn Sie diese Methode mit preserveTextElements "set to false" aufrufen, Heading1 wird sie in einen Paragraph Zeitpunkt konvertiert, an dem die TextRange Methode gespeichert wird. Wenn Sie diese Methode mit preserveTextElements "Set" trueaufrufen, wird sie gespeichert, Heading1 ohne konvertiert zu werden. Um benutzerdefinierte Textelemente beizubehalten, dataFormat muss auf DataFormats.Xaml.

Save(Stream, String, Boolean) wird in der .NET Framework Version 3.5 eingeführt. Weitere Informationen finden Sie unter "Versionen und Abhängigkeiten".
