我想将 excel 表数据上传到 sql sever 2008，我的所有数据，即我的 excel 表中的数字和字母表都将上传到数据库表中，但 $ 符号不会上传到那里，因为我必须使用货币作为一列，$sign 将上传文本数据但不上传数字.....请让我知道这个问题

这是我的代码

如果您想要货币列，因为Int您无法在其中插入$符号，decimal因为默认整数数据类型不允许它。因此，要解决您的问题，请将 curreny 设置为Varchar并插入数据，$100.00 并在显示时将其显示出来。在前端进行计算时，$使用关键字删除符号Contains并将其转换为Double并进行计算。希望能帮助到你

好的，请尝试使用此链接将数据从 excel 存储到 gridview（仅作为示例），您只需更改您的需求。我还使用该代码进行了测试，以将包含$符号的数据存储在单元格中，并将其存储在数据库中也显示相同data from the database with $ symbols in the same cells。看看它，它可能有用。

从 Excel 加载 Gridview

只需根据您的需要更改代码。
