Question

我想将该表作为pdf下载到视图中。为此，我使用此代码。

      public void pdf()
      {
          MemoryStream workStream = new MemoryStream();
          Document document = new Document();
          PdfWriter.GetInstance(document, workStream).CloseStream = false;

          document.Open();

         document.Add(new Paragraph("msg"));
          document.Add(new Paragraph(DateTime.Now.ToString()));
          document.Close();

          byte[] byteInfo = workStream.ToArray();
          workStream.Write(byteInfo, 0, byteInfo.Length);
          workStream.Position = 0;
          Response.Buffer = true;

          Response.AddHeader("Content-Disposition", "attachment; filename= " + Server.HtmlEncode("doc.pdf"));
          Response.ContentType = "APPLICATION/pdf";
          Response.BinaryWrite(byteInfo);
          //return new FileStreamResult(workStream, "application/pdf");
      }

但它仅以pdf格式显示“msg”。我想以pdf格式显示表格。我怎么能这样做

现在你只打印段落，因为你调用它document.Add(new Paragraph("msg"));

正确的下载PDF格式：

  public static void DownloadPDF(HttpResponse response,string fileRelativePath)
{
    try
    {
        string contentType = "";
        //Get the physical path to the file.
        string FilePath = HttpContext.Current.Server.MapPath(fileRelativePath);

        string fileExt = Path.GetExtension(fileRelativePath).Split('.')[1].ToLower();

        if (fileExt == "pdf")
        {
            //Set the appropriate ContentType.
            contentType = "Application/pdf";
        }

        //Set the appropriate ContentType.
        response.ContentType = contentType;
        response.AppendHeader("content-disposition", "attachment; filename=" + (new FileInfo(fileRelativePath)).Name);

        //Write the file directly to the HTTP content output stream.
        response.WriteFile(FilePath);
        response.End();
    }
    catch
    {
       //To Do
    }
}
