Question

在我在控制器中的方法中，我使用以下代码来保存pdf。

HtmlDocument doc = new HtmlDocument();
            doc.LoadHtml(htmlContent);
            HtmlNode node = doc.GetElementbyId("DetailsToPDF");
            HtmlToPdfConverter htmlToPdf = new HtmlToPdfConverter();
            var pdfBytes = htmlToPdf.GeneratePdf("<html><body>" + node.InnerHtml + "</body></html>");

            Response.ContentType = "application/pdf";
            Response.ContentEncoding = System.Text.Encoding.UTF8;
            Response.AddHeader("Content-Disposition", "attachment; filename=TEST.pdf");
            Response.BinaryWrite(pdfBytes);
            Response.Flush();
            Response.End();

调试器中没有任何异常，一切都过去了。但是文件未保存。我做错了什么？

Answer 1

在ASP.NET MVC中返回文件的推荐方法是使用File()辅助方法：

public ActionResult Download()
{
  // Starting with pdfBytes here...
  // ...
  var pdfBytes = htmlToPdf.GeneratePdf("<html><body>" + node.InnerHtml + "</body></html>");
  var contentDisposition = new System.Net.Mime.ContentDisposition
  {
      FileName = "TEST.pdf",
      Inline = false
  };
  Response.AppendHeader("Content-Disposition", contentDisposition.ToString());
  return File(pdfBytes, "application/pdf");
}

将PDF文件保存在ASP .NET MVC的Downloads文件夹中
