使用下拉列表从Excel电子表格中提取数据
有没有办法，我可以使用Excel电子表格，然后将饲料到我的HTML / C＃程序。 我有多达10个dropdownlists（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]}，硬编码他们在html层中，这些DDL的名字和值代表的是excel电子表格中的数据，我需要编写从电子表格中抽取某些数据的代码，当且仅当在DDL中select了这个特定的值。试图通过尝试让我导入电子表格，并使用它像一个面板里面的电子表格或什么我需要有一种方式，让我补充它更像一个数据库，我需要能够编写函数/像SQL查询一样操作的语句。感谢您花时间阅读本文，并试图帮助我。
