Örnekler

Aşağıdaki örnekte Save yönteminin kullanımı gösterilmektedir.

// 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;

Açıklamalar

Bu yöntem döndürdüğünde, stream açık bırakılır ve stream içindeki geçerli konum tanımlanmamıştır.

Kaydetme işleminin bir parçası olarak, geçerli seçimdeki içerik dataFormattarafından belirtilen veri biçimine dönüştürülebilir.

Özel durumlar

Açıklamalar

preserveTextElements falseolduğunda, özel TextElement nesneleri bilinen TextElement türleri olarak kaydedilir. Örneğin, Paragraph'den devralan Heading1adlı özel bir TextElement oluşturduğunuzu varsayalım. preserveTextElements falseolarak ayarlanmış bu yöntemi çağırdığınızda, TextRange kaydedildiğinde Heading1 bir Paragraph dönüştürülür. preserveTextElements trueolarak ayarlanmış bu yöntemi çağırdığınızda Heading1 dönüştürülmeden kaydedilir. Özel metin öğelerini korumak için dataFormatDataFormats.Xamlolarak ayarlanmalıdır.

Save(Stream, String, Boolean) .NET Framework sürüm 3.5'te kullanıma sunulmuştur. Daha fazla bilgi için bkz. Sürümleri ve Bağımlılıklar.
