问题描述
我正在尝试建立一个页面以将数据从excel加载到sql server，我在行
上收到一条错误消息
Hi I am trying to build a page to load data from excel to sql server, I am getting a error message at the line
ProductID = Convert.ToInt32(SSAdapter.InsertProductQuery(PartNumber, Description, Convert.ToDecimal(UnitCost), Convert.ToDecimal(Postage), QtyAvailable.ToInt32, MakeID, DealerID));
说它的格式不正确，任何人都可以提供正确格式的帮助吗?
整个页面是
saying that it is formatted incorrectly can anyone help with the correct format?
