How to save a document in PDF format C# and VB.Net

How to save a document in PDF format C# and VB.Net

  1. Save to a file:
    
                // The file format will be detected automatically from the file extension: ".pdf".
                dc.Save(@"d:\Book.pdf");
    

    To not rely on the file extension and guarantee that the file contents is really PDF (Adobe Portable Format), you may specify PdfSaveOptions as 2nd parameter.

                dc.Save(@"d:\Book.pdf", new PdfSaveOptions());
    

    In PdfSaveOptions you can also set various options which affects to the saving process.

                dc.Save(@"d:\Book.pdf", new PdfSaveOptions()
                {
                    Compliance = PdfCompliance.PDF_A,
                    PreserveFormFields = true
                });
    
  2. Save to a Stream:
                // Let's save our document to a MemoryStream.
                using (MemoryStream ms = new MemoryStream())
                {
                    dc.Save(ms, new PdfSaveOptions()
                    {
                        PageIndex=0,
                        PageCount=1,
                        Compliance = PdfCompliance.PDF_A
                    });             
                }
