使用pdfsharp将wpf布局保存为pdf,c#

Question

我是c#,wpf和pdfsharp库的新手.这是我的XAML代码:

<Grid>
    <zoom:ZoomControl>
    <graphsharp:GraphLayout x:Name="graphLayout"
                            Graph="{Binding ElementName=root, Path=GraphToVisualize}" 
                            LayoutAlgorithmType="FR"
                            OverlapRemovalAlgorithmType="FSA"
                            HighlightAlgorithmType="Simple"></graphsharp:GraphLayout>
    </zoom:ZoomControl>
    <Button Content="Button" Height="23" Name="button1" Width="75" Margin="12,294,658,412" Click="button1_Click" />
</Grid>

我现在想要使用Pdfsharp将我的"graphLayout"保存到pdf文件中.我创建了一个按钮,基本上使用了pdfsharp wiki中的"hello world"示例代码来启动.

PdfDocument document = new PdfDocument();
        document.Info.Title = "Created with PDFsharp";
        PdfPage page = document.AddPage(); 
        XGraphics gfx = XGraphics.FromPdfPage(page);
        XFont font = new XFont("Verdana", 20, XFontStyle.BoldItalic);
        gfx.DrawString("My Graph", font, XBrushes.Black,
            new XRect(0, 0, page.Width, page.Height),
            XStringFormats.TopCenter);
        const string filename = "MyGraph.pdf";
        document.Save(graphLayout+filename);
        Process.Start(filename);

我得到一个pdf,但其中只有文字.有人可以告诉我,我如何将整个布局保存为PDF格式？谢谢

我不知道你可以直接从WPF转换为PDF,但它很简单

使用WPF < - > XPS < - > PDF.

MemoryStream lMemoryStream = new MemoryStream();
Package package = Package.Open(lMemoryStream, FileMode.Create);
XpsDocument doc = new XpsDocument(package);
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(doc);
writer.Write(dp);
doc.Close();
package.Close();

var pdfXpsDoc = PdfSharp.Xps.XpsModel.XpsDocument.Open(lMemoryStream);
PdfSharp.Xps.XpsConverter.Convert(pdfXpsDoc, d.FileName, 0);

其中dp是你的视觉/布局
