  string localFileName = path + Path.DirectorySeparatorChar + fileName;
                FileInfo file = new FileInfo(localFileName);
                using (ExcelPackage package = new ExcelPackage(file))

                    ExcelWorkbook wb = package.Workbook;

                    //配置文件属性  
                    wb.Properties.Title = "库存导入模板";
                    // 添加worksheet
                    ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("商品库存");
                    //添加头
                    worksheet.Cells[1, 1].Value = "商品ID";
                    worksheet.Cells[1, 2].Value = "商品名称";

                    //获取当前商户库存数据模板
                    var items = _pser.GetImportInnentoryList(CurrentVendorID);
                    int rowindex = 1;
                    foreach (var item in items)
