IE不会在浏览器中显示生成的PDF

如果我使用

,我已经尝试了许多工作来实现这一点
Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", newFileInfo.Name));

而不是

Response.AddHeader("Content-Disposition", string.Format("inline; filename={0}", newFileInfo.Name));

它可以工作,但是我需要在浏览器窗口中显示它才能正常工作。内联视图在Chrome中正常运行。我已经尝试过使用Response.BinaryWrite和Response.WriteFile,它没有任何区别。

我正在使用Internet Explorer 9。

这是我的代码:

    Response.Clear();
    Response.ClearHeaders();
    Response.ClearContent();

    Response.Buffer = true;

    Response.ContentType = "application/pdf";
    Response.AddHeader("Pragma", "public");
    Response.AddHeader("expires", "0");
    Response.AddHeader("Cache-Control", "no-cache");
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    string filePath = Request["file"];
    string signatureFile = Request["SignatureImage"];
    double xPos = Convert.ToDouble(Request["X-Pos"]);
    double yPos = Convert.ToDouble(Request["Y-Pos"]);
    double scale = Convert.ToDouble(Request["Scale"]);

    if (!string.IsNullOrEmpty(filePath))
    {
        try
        {                
            string newFile = PDFTools.SignPDF(filePath, signatureFile, xPos, yPos, scale, tempDirectory);
            var newFileInfo = new FileInfo(newFile);
            Response.AddHeader("Content-Disposition", string.Format("inline; filename={0}", newFileInfo.Name));
            Response.AddHeader("content-length", newFileInfo.Length.ToString());

            Response.TransmitFile(newFile);
            Response.Flush();
            Response.Close();
        }
        catch (Exception ex)
        {
            Debug.WriteLine("Error: " + ex.Message);
            Debug.WriteLine("at " + ex.StackTrace);
        }
        finally
        {
            Response.End();
        }
    }

谢谢你的时间!

Chrome有一个内置的PDF查看器,但Internet Explorer没有。您是否为Web视图安装并配置了外部PDF查看器(即Adobe Acrobat或Adobe Reader)?

对不起,没有代表,也无法发表评论。
