yte[] filec = (byte[])(ds.Tables[0].Rows[0]["FContent"]);
            Response.Clear();
            string FileName = ds.Tables[0].Rows[0]["FName"].ToString();
            string FullName = ds.Tables[0].Rows[0]["FullName"].ToString();
            //类型
            string imageType = System.IO.Path.GetExtension(FullName).ToLower();
            if (imageType == ".jpg")
            {
                ResponseEnd(filec, FullName);
            }
            if (imageType == ".doc")
            {
                ContentType = "application/msword";
                Response.ContentType = ContentType;
                Response.ContentEncoding = System.Text.Encoding.Unicode;
                Response.AddHeader("Content-Disposition ", "attachment;filename=" + FullName);
                Response.Charset = "GB2312 ";
                Response.OutputStream.Write(filec, 0, filec.Length);
                Response.End();
            }
            if (imageType == ".xls")
            {
                ContentType = "application/vnd.ms-excel";
                Response.ContentType = ContentType;
                Response.ContentEncoding = System.Text.Encoding.Unicode;
                Response.AddHeader("Content-Disposition ", "attachment;filename=" + FullName);
                Response.Charset = "GB2312 ";
                Response.OutputStream.Write(filec, 0, filec.Length);
                Response.End();
            }
            if (imageType == ".pdf")
            {
                ContentType = "application/pdf";
                Response.ContentType = ContentType;
                Response.ContentEncoding = System.Text.Encoding.Unicode;
                Response.AddHeader("Content-Disposition ", "attachment;filename=" + FullName);
                Response.Charset = "GB2312 ";
                Response.OutputStream.Write(filec, 0, filec.Length);
                Response.End();
            }
 if (imageType == ".pdf")
或 if (imageType == ".txt")时不显示
