解决方案

您已经在下载时发布了此问题按钮上的ID卡pdf文件使用上面的代码显示错误,因为访问路径'C:\'被拒绝.... [ ^ ]


HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader
("Content-Disposition", "attachment;filename=iTextSharpExample.pdf");
HttpContext.Current.Response.Charset = "";
HttpContext.Current.Response.ContentType = "application/pdf";
StringWriter stringwrite = new StringWriter();
HtmlTextWriter htmlwrite = new HtmlTextWriter(stringwrite);
dvText.RenderControl(htmlwrite);
StringReader sr = new StringReader(stringwrite.ToString());
Document pdfDoc = new Document(PageSize.A4, 50, 50, 25, 25);
PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
