PDFsharp save to MemoryStream

I want to save a PdfSharp.Pdf.PdfDocument by its Save method to a Stream, but it doesn't attach the PDF header settings to it. So when I read back the Stream and return it to the user, he see that the PDF file is invalid. Is there a solution to attach the PDF header settings when PDFsharp saves to memory?

pdfsharp pdf stream .net c#

So the solution:

MigraDoc.DocumentObjectModel.Document doc = new MigraDoc.DocumentObjectModel.Document();
MigraDoc.Rendering.DocumentRenderer renderer = new DocumentRenderer(doc);
MigraDoc.Rendering.PdfDocumentRenderer pdfRenderer = new MigraDoc.Rendering.PdfDocumentRenderer();
pdfRenderer.PdfDocument = pDoc;
pdfRenderer.DocumentRenderer = renderer;
using (MemoryStream ms = new MemoryStream())
{
  pdfRenderer.Save(ms, false);
  byte[] buffer = new byte[ms.Length];
  ms.Seek(0, SeekOrigin.Begin);
  ms.Flush();
  ms.Read(buffer, 0, (int)ms.Length);
}

There is this MigraDoc stuff which comes with PdfSharp, but i hardly found any proper doc/faq for it. After hours of googling i've found a snippet which was something like this. Now it works.

Thanks Misnyo Solution. But for me it works like this:

        Document document = new Document();
        PdfDocumentRenderer pdfRenderer = new PdfDocumentRenderer();   

        //Add to document here.......

        //render the document with pdf renderer
        pdfRenderer.Document = document;
        pdfRenderer.RenderDocument();

        //Save renderer result into stream   
        using(MemoryStream ms = new MemoryStream())
        {
            pdfRenderer.PdfDocument.Save(ms, false);
            byte[] buffer = new byte[ms.Length];
            ms.Seek(0, SeekOrigin.Begin);
            ms.Flush();
            ms.Read(buffer, 0, (int)ms.Length);
            ms.Position = 0;
        }
