您需要在服务器上安装Adobe PDF才能使用iTextSharp吗

我在我的开发机器上开发了一个解决方案：

1. 通过C打开文件路径服务器端的PDF#
2. 将它们合并在一起
3. Response.BinaryWrite将合并后的PDF推送到浏览器

在本地DEV上效果很好。当推送到服务器时，它会在浏览器窗口中得到一些"二进制胡言乱语"。

Adobe或Foxit阅读器没有安装在服务器上，但它安装在我的本地开发机器上。我的理解是iTextSharp允许你根本不需要安装PDF阅读器，但它是吗？或者这可能是IIS的事情，其中.pdf没有被列为文件类型。。。

以下是一些示例代码：

 // First set up the response and let the browser know a PDF is coming
            context.Response.Buffer = true;
            context.Response.ContentType = "application/pdf";
            context.Response.AddHeader("Content-Disposition", "inline");
            List<string> PDFs = new List<string>();
            PDFs.Add(@"c:'users'shane'documents'visual studio 2010'Projects'PDFMultiPrintTester'PDFMultiPrintTester'TEST1.pdf");
            PDFs.Add(@"c:'users'shane'documents'visual studio 2010'Projects'PDFMultiPrintTester'PDFMultiPrintTester'TEST2.pdf");
            PDFs.Add(@"c:'users'shane'documents'visual studio 2010'Projects'PDFMultiPrintTester'PDFMultiPrintTester'TEST3.pdf");
            // Second, some setup stuff
            System.IO.MemoryStream MemStream = new System.IO.MemoryStream();
            iTextSharp.text.Document doc = new iTextSharp.text.Document();
            iTextSharp.text.pdf.PdfReader reader = default(iTextSharp.text.pdf.PdfReader);
            int numberOfPages = 0;
            int currentPageNumber = 0;
            iTextSharp.text.pdf.PdfWriter writer = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, MemStream);
            doc.Open();
            iTextSharp.text.pdf.PdfContentByte cb = writer.DirectContent;
            iTextSharp.text.pdf.PdfImportedPage page = default(iTextSharp.text.pdf.PdfImportedPage);
            int rotation = 0;
            foreach (string f in PDFs)
            {
                // Third, append all the PDFs--THIS IS THE MAGIC PART
                byte[] sqlbytes = null;
                sqlbytes = ReadFile(f);
                reader = new iTextSharp.text.pdf.PdfReader(sqlbytes);
                numberOfPages = reader.NumberOfPages;
                currentPageNumber = 0;
                while ((currentPageNumber < numberOfPages))
                {
                    currentPageNumber += 1;
                    doc.SetPageSize(PageSize.LETTER);
                    doc.NewPage();
                    page = writer.GetImportedPage(reader, currentPageNumber);
                    rotation = reader.GetPageRotation(currentPageNumber);
                    if ((rotation == 90) | (rotation == 270))
                    {
                        cb.AddTemplate(page, 0, -1f, 1f, 0, 0, reader.GetPageSizeWithRotation(currentPageNumber).Height);
                    }
                    else
                    {
                        cb.AddTemplate(page, 1f, 0, 0, 1f, 0, 0);
                    }
                }
            }
            // Finally Spit the stream out
            if (MemStream == null)
            {
                context.Response.Write("No Data is available for output");
            }
            else
            {
                doc.Close();
                context.Response.BinaryWrite(MemStream.GetBuffer());
                context.Response.End();
                MemStream.Close();
            }
        }
    }
    public static byte[] ReadFile(string filePath)
    {
        byte[] buffer;
        FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read);

            // read until Read method returns 0 (end of the stream has been reached)
            while ((count = fileStream.Read(buffer, sum, length - sum)) > 0)
                sum += count;  // sum is a buffer offset for next reading
