PDF下载问题 [英] Pdf download problem

问题描述

我有一张Microsoft图表.我想在单击按钮时将该图表导出为pdf.
这是我在单击按钮时的代码.

Hi,
I have one Microsoft chart. I want to export that chart into pdf on button click.
This is my code in button click.

Response.Clear();
        Response.AddHeader("content-disposition", "attachment;filename=ForwardLoadHistory.pdf");        
        Response.ContentType = "application/pdf";        
        Response.Charset = "";
        StringWriter stringWriter = new StringWriter();
        HtmlTextWriter htmlWriter = new HtmlTextWriter(stringWriter);
        chtEstHoursRemaining.RenderControl(htmlWriter);
        Response.Output.Write(stringWriter.ToString());
        Response.Flush();
        Response.End();

文件正在下载.它正在正确呈现.当我在写字板中打开文件时，它会正确显示渲染的文本，但是当我尝试打开文件时，它会出现以下错误.

File is downloading .It is rendering properly. When i open file in wordpad it is properly showing rendered text but when i try to open file it is giving following error.

" Adobe reader could not open file 'ForwardLoadHistory.pdf' because it is either not a supported file type or because the  file has been damaged(for example it was sent as an email attachment and wasn't corrcetly decoded)".

我尝试使用ITextSharp做到这一点，但在解析时却出现以下错误.

I try to do it with ITextSharp but is giving me following error while parsing.

Illegal characters in path

请提供一些有用的解决方案.

Please give some helpful solution.

嗨
试试这个


Response.AppendHeader("content-disposition"，"attachment; filename = ForwardLoadHistory.pdf");
Response.ContentType =应用程序/pdf";
Response.WriteFile(Server.MapPath("ForwardLoadHistory.pdf"));//

Response.Flush();

Response.Close();
//System.Threading.Thread.Sleep(5000);
System.IO.File.Delete(Server.MapPath("ForwardLoadHistory.pdf"));
Response.End();

hi
try this one


Response.AppendHeader("content-disposition", "attachment; filename=ForwardLoadHistory.pdf");
Response.ContentType = "Application/pdf";
Response.WriteFile(Server.MapPath("ForwardLoadHistory.pdf"));//

Response.Flush();

Response.Close();
//System.Threading.Thread.Sleep(5000);
System.IO.File.Delete(Server.MapPath("ForwardLoadHistory.pdf"));
Response.End();

Response.ContentType = "application/pdf";
            Response.AddHeader("content-disposition", "attachment;filename=Vendors List.pdf");
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            StringWriter sw = new StringWriter();
            HtmlTextWriter hw = new HtmlTextWriter(sw);
            hw.Write("<center><h3>Vendors List</h3></center><br /><br /><br /><br />");
            grdVendorList.AllowPaging = false;
            grdVendorList.DataBind();
            grdVendorList.RenderControl(hw);
            StringReader sr = new StringReader(sw.ToString());
            Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
            HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
            PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
            pdfDoc.Open();
            htmlparser.Parse(sr);
            pdfDoc.Close();
            Response.Write(pdfDoc);
            Response.End();
