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
                });             
            }
