Question

我是.net开发者。在这里，我只想创建pdf报告。更多信息我包括这段代码：

Document document = new Document(PageSize.A4, 88f, 88f, 10f, 10f);
        Font NormalFont = FontFactory.GetFont("Arial", 12, Font.NORMAL, Color.BLACK);
        using (System.IO.MemoryStream memoryStream = new System.IO.MemoryStream())
        {
            PdfWriter writer = PdfWriter.GetInstance(document, memoryStream);
            Phrase phrase = null;
            PdfPCell cell = null;
            PdfPTable table = null;
            Color color = null;

            document.Open();

            //Header Table
            table = new PdfPTable(2);
            table.TotalWidth = 500f;
            table.LockedWidth = true;
            table.SetWidths(new float[] { 0.3f, 0.7f });

            //Company Logo
            cell = ImageCell("../images/easyweb_logo.gif", 30f, PdfPCell.ALIGN_CENTER);
            table.AddCell(cell);

            //Company Name and Address
            phrase = new Phrase();
            phrase.Add(new Chunk("Electrocom Technology India Limited\n\n", FontFactory.GetFont("Arial", 16, Font.BOLD, Color.RED)));

            table.AddCell(cell);

            document.Close();
            byte[] bytes = memoryStream.ToArray();
            memoryStream.Close();
            Response.Clear();
            Response.ContentType = "application/pdf";
            Response.AddHeader("Content-Disposition", "attachment; filename=PostRecord.pdf");
            Response.ContentType = "application/pdf";
            Response.Buffer = true;
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.BinaryWrite(bytes);
            Response.End();
            Response.Close();

这里只显示少数字段。

转到您的代码：

table.AddCell(cell);
document.Close();

现在添加如下一行：

table.AddCell(cell);
document.Add(table);
document.Close();

您正在创建一个表对象，但您没有将其添加到文档中。
