将内存中的pdf转换为字节[]

MemoryStream -从这里你可以得到你的 byte[] 通过呼叫 GetBuffer

显然可以将()文档保存到流对象:

我记得不久前用Aspose.pdf做过类似的事情。下面是我写的一些POC代码,它打开了一个PDF页面,并将其返回。希望有帮助。。

   public ActionResult Index(int pageNumber)
    {


        ActionResult result = null;
        var path = Server.MapPath("~/Content/BigPdf.pdf");

        if (pageNumber == 0)
        {

            result = new FilePathResult(path, "application/pdf");
        }

        else
        {
            string inFile = path;

            string outFile = ".\\ExtractStream.pdf";



            //Creating stream objects holding the PDF files in Open Mode

            var inStream = new FileStream(inFile, FileMode.Open);


            //Creating output stream object that will store the extracted pages as a PDF file

            var outputStream = new MemoryStream();



            //Instantiating PdfFileEditor object

            var editor = new PdfFileEditor();



            //Creating an array of integers having numbers of the pages to be extracted from PDF file

            var pages = new int[] { pageNumber };



            //Calling Extract method

            editor.Extract(inStream, pages, outputStream);
            inStream.Close();


            //Closing output stream
            outputStream.Seek(0, SeekOrigin.Begin);//rewind stream


            var converter = new PdfConverter();

            converter.BindPdf(outputStream);

            converter.DoConvert();


            var imageStream = new MemoryStream();

            while (converter.HasNextImage())
            {

                converter.GetNextImage(imageStream, ImageFormat.Jpeg );



            }



            imageStream.Seek(0, SeekOrigin.Begin);//rewind stream

            result = new FileStreamResult(imageStream, "image/Jpeg");


        }

        return result;

    }
