Question

有没有办法可以使用excel电子表格然后输入我的html / c＃程序。我有多达10个下拉列表（DDL），它们都有不同的值（例如：{Ram [8,16,32,64]}，另一个是{City [HSV，DAL，SLC，DNV]}，硬编码到它们位于html层。这些DDL的名称和值代表excel电子表格中的数据。我需要编写从电子表格中提取某些数据的代码，当且仅当在DDL中选择了特定值时。我所有的事情都是尝试通过尝试让我导入电子表格并将其用作面板内的电子表格或其他东西。我需要有一种方法可以让我更像一个数据库修补它。我需要能够编写函数/像SQL查询一样运作的语句。感谢您抽出时间阅读本文并试图帮助我。
