我們一般下載中文文件名一般會utf-8編碼再下載，火狐瀏覽器會出現文件名亂碼，解決辦法，火狐瀏覽器文件名不編碼，直接下載：

   HttpContext curContext = HttpContext.Current;

            // 設置編碼和附件格式
            curContext.Response.ContentType = "application/vnd.ms-excel";
            curContext.Response.ContentEncoding = Encoding.UTF8;
            curContext.Response.Charset 
 
= "";
            strFileName = strFileName + DateTime.Now.ToString("yyyyMMddHHmmss");

            string userAgent = curContext.Request.ServerVariables["http_user_agent"].ToLower();
            if (userAgent.IndexOf("firefox", StringComparison.Ordinal) == -1) 
            {
                strFileName 
 
= HttpUtility.UrlEncode(strFileName, Encoding.UTF8) + ".xls";
            }
            curContext.Response.AppendHeader("Content-Disposition",
                "attachment;filename=" + strFileName);

            curContext.Response.BinaryWrite(ListToExcel(list, strFileName, titleDic).GetBuffer());
            curContext.Response.End();
