一个下载文件的问题，各位帮忙看下。。。急急急

需求：将数据导入到Excel里，并下载。

问题所在：在IE下，会下载当前页面的源代码。看图：

火狐下正常,看图：

代码：

        /// <summary>

        /// 数据导出到Excel 

        /// </summary>

        /// <param name="table">数据表</param>

        /// <param name="context">上下文对象</param>

        /// <param name="fileName">文件名</param>

        public static void RenderToExcelBrowser(DataTable table, HttpContext context, string fileName)

        {

            MemoryStream ms = new MemoryStream();

            using (table)

            {

                IWorkbook workbook = new XSSFWorkbook();

                ISheet sheet = workbook.CreateSheet();

                IRow headerRow = sheet.CreateRow(0);              

                foreach (DataColumn column in table.Columns)

                    headerRow.CreateCell(column.Ordinal).SetCellValue(column.Caption);



                // handling value.

                int rowIndex = 1;

                foreach (DataRow row in table.Rows)

                {

                    IRow dataRow = sheet.CreateRow(rowIndex);

                    foreach (DataColumn column in table.Columns)

                    {

                        dataRow.CreateCell(column.Ordinal).SetCellValue(row[column].ToString());

                    }

                    rowIndex++;

                }

                workbook.Write(ms);

                ms.Flush();

            }//.xlsx

            fileName=fileName+"-"+ DateTime.Now.ToString("yyyyMMddHHmmssfff") + ".xlsx";  



            context.Response.ContentType = "application/octet-stream";

            context.Response.AddHeader("Content-Disposition", "attachement;filename=" + fileName);

            context.Response.AddHeader("Content-Length", ms.ToArray().Length.ToString()); 

        

            //context.Response.AddHeader("Content-Disposition", "attachment;fileName=" + fileName);

            //System.Web.HttpContext.Current.Response.AddHeader("Content-Length", ms.ToArray().Length.ToString());

            context.Response.BinaryWrite(ms.ToArray());

        }
