使用以下代码

公共对象ImportExcel（） { 尝试 { ProductClass objProduct = new ProductClass（）; DbManager管理器=新的DbManager（）; DataTable dtProduct = objProduct.ImportFromExcel（HttpContext.Current.Session [“ TempFilePath”]。ToString（））; 字符串类别= string.Empty; 字符串Brand = string.Empty; 字符串模型= string.Empty; 字符串Branch = string.Empty; 字符串数量=字符串。空; 字符串ProductDescription = string.Empty; 字符串ClaimNumbers = string.Empty;
            if (dtProduct != null && dtProduct.Rows.Count > 0)
            {

                for (int i = 0; i < dtProduct.Rows.Count; i++)
                {
                    Category = dtProduct.Rows[i]["Category"].ToString().Trim();
                    Brand = dtProduct.Rows[i]["Brand"].ToString().Trim();
                    Model = dtProduct.Rows[i]["Model"].ToString().Trim();
                    Branch = dtProduct.Rows[i]["Branch"].ToString().Trim();
                    Quantity = dtProduct.Rows[i]["Quantity"].ToString().Trim();
                    ProductDescription = dtProduct.Rows[i]["Item Description"].ToString().Trim();
                    InventoryClass obj = new InventoryClass();
                    int result = obj.ImportStock(Category, Brand, Model, ProductDescription, Branch, Quantity);

                }

                return new { Result = "OK", Message = "Imported Successfully", ClaimNumbers = ClaimNumbers.TrimEnd(',') };

            }
        }
        catch (Exception ex)
        {
            return new { Result = "error", Message = "Fail to import" };
        }
        return null;
    }

} }
