将 HTML 转换为 pdf 并将其保存到给定位置，而无需打开“另存为”或“下载”窗口

Question

我正在将 html 转换为 pdf。它工作正常。但是当我尝试将 html 保存到任何位置时，它会给我错误Network path not found。 我有一些代码行

  #region Trying to convert pdf

        Response.ContentType = "application/pdf";
        Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        StringWriter sw = new StringWriter();
        HtmlTextWriter hw = new HtmlTextWriter(sw);
        StringReader sr = new StringReader(htmlStringToConvert);
        iTextSharp.text.Document pdfDoc = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 10f, 10f, 100f, 0f);
        HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
        PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
        pdfDoc.Open();
        htmlparser.Parse(sr);
        pdfDoc.Close();
        Response.Write(pdfDoc);
        Response.End();
        #endregion

htmlparser.Parse(sr) 出现错误。

提前致谢

Response.ContentType = "application/pdf";
 Response.AddHeader("content-disposition", "attachment;filename=Panel.pdf");

        StringWriter sw = new StringWriter();

        HtmlTextWriter hw = new HtmlTextWriter(sw);
        DivMaster.RenderControl(hw);

        StringReader sr = new StringReader(sw.ToString());

        Document pdfDoc = new Document(PageSize.A4, 20, 20, 10, 20);

        HTMLWorker htmlparser = new HTMLWorker(pdfDoc);


        PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
        pdfDoc.Open();
        htmlparser.Parse(sr);
        pdfDoc.Close();
        Response.Write(pdfDoc);
        Response.End();

在设计页面中添加 DivMaster (div) 并在该 DivMaster 中添加您的 HTML 代码。 注意：在整个 HTML 设计中使用 % 或 px。
