protected void Page_Load(object sender, EventArgs e)

    {

        string FullFileName = "";

 

        //ASP.NET下载文件(弹出打开保存文件对话框) 

        //fileURL为带路径的文件全名 

 

        //无错版: 

        try

        {

            string FileName ="";

            FileName = @"UserFiles/Matytype快捷键.txt";

            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

                Response.Write("File not exist");

            }

        }

        catch

        {

            //打开时异常了

            Response.Write("Exception occured");

        } 

 


    }
