生成pdf下载问题。。。。。。。。。。
我有一个页面是把数据生成pdf下载的。但有个问题是：如果客户装了pdf软件，有的就会直接在IE中打开。现在我想只能下载，不要在IE中打开要怎么做？ 附上下载的代码。

 Response.AddHeader("Content-Disposition", "inline; filename=CalcTariff.pdf");
  Response.AddHeader("Content-Length", ms.Length.ToString());
  Response.HeaderEncoding = System.Text.Encoding.GetEncoding("big5");
  Response.Cache.SetCacheability(HttpCacheability.NoCache);
  Response.ContentType = "application/pdf"; 
  Response.BinaryWrite(ms.ToArray());
  Response.End();

下载时，target转到一个页面，或者转到一个 .ashx的简单页，然后代码中以类似如下代码编写：

FileStream fs = new FileStream(dir, System.IO.FileMode.Open);
context.Response.Buffer = false;
context.Response.AddHeader("Connection", "Keep-Alive");
context.Response.ContentType = "application/octet-stream";
context.Response.AddHeader("Content-Disposition", "attachment;filename=" + System.IO.Path.GetFileName(dir));
context.Response.AddHeader("Content-Length", fs.Length.ToString());

using (fs)
{
byte[] data = new byte[1024];

int byteReads;
do
{
byteReads = fs.Read(data, 0, data.Length);
context.Response.BinaryWrite(data);
} while (byteReads > 0);

}

context.Response.End();

C# code

string FullFileName = "";
                        try
            {
                string FileName = "acrobat.pdf";
                FullFileName = Server.MapPath(FileName);
                //FileName--要下载的文件名 
                FileInfo DownloadFile = new FileInfo(FullFileName);
                if (DownloadFile.Exists)
                {
                    Response.Clear();
                    Response.ClearHeaders();
                    Response.Buffer = false;
                    Response.ContentType = "application/octet-stream";
                    Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(DownloadFile.FullName, System.Text.Encoding.ASCII));
                    Response.AppendHeader("Content-Length", DownloadFile.Length.ToString());
                    Response.WriteFile(DownloadFile.FullName);
                    Response.Flush();
                    Response.End();
                }
                else
                {
                    //文件不存在
                }
            }
            catch
            {
                //打开时异常了
            }
