c#发送文件(pdf, html或rtf)到打印机

我在c#中打印文件时有一个问题。如何打印任何具有双面打印可能性的文件。

        ProcessStartInfo info = new ProcessStartInfo();
        info.Verb = "print";
        info.FileName = @"c:'output.pdf";
        info.CreateNoWindow = true;
        info.WindowStyle = ProcessWindowStyle.Hidden;
        Process p = new Process();
        p.StartInfo = info;
        p.Start();
        p.WaitForInputIdle();
        System.Threading.Thread.Sleep(3000);
        if (false == p.CloseMainWindow())
            p.Kill();

但是我不满意，因为我不能在这里设置打印参数。我如何使用PrintDocument类做到这一点?

我使用Spire PDF将PDF转换为图像。

            PdfDocument pdf = new PdfDocument();
            pdf.LoadFromFile("e:''proba1.pdf");
            BitmapSource source;
            Bitmap bmp;
            for (int i = 1; i < pdf.Pages.Count + 1; i++)
            {
                source = pdf.SaveAsImage(i);
                bmp = SourceToBitmap(source);
                bmp.Save(string.Format("result-{0}.png", i), ImageFormat.Png);
            }

但是，我得到一个错误:

Error   1   Cannot implicitly convert type 'System.Drawing.Image' to 'System.Windows.Media.Imaging.BitmapSource'    C:'Users'Łukasz'documents'visual studio 2013'Projects'WpfApplication1'WpfApplication1'MainWindow.xaml.cs    90  26  FileMonitor

你可以使用Free . net PDF Library (Free, on visualstudiogallery)。将PDF转换为图像并使用PrintDocument打印....

For Spire。. NET (from教程)

PdfDocument doc = new PdfDocument(); 
doc.LoadFromFile("sample.pdf"); 
Bitmap bmp = doc.SaveAsImage(0); 
bmp.Save("convertToBmp.bmp", ImageFormat.Bmp);
