Question

我想将excel表格数据上传到sql sever 2008，我的excel表格中的所有数据，即数字和字母表将在数据库表格中上传，但$ sign不会上传，因为我必须使用货币作为列，$ sign将上传文本数据但不上传数字.....请让我知道这个问题

Answer 1

如果您希望货币列为Int，则无法在其中插入$符号和decimal，因为默认的整数数据类型将不允许它。因此，要解决您的问题，请将当前值设为Varchar并将数据插入$100.00之类的内容而显示它只是显示它。在前端进行计算时，使用$关键字删除Contains符号并将其转换为Double并进行计算。希望它有所帮助

Answer 2

好的尝试此链接用于存储从excel到gridview的数据（仅作为示例），您只需更改您的需求。我还测试了该代码，以便在单元格中存储包含$符号的数据，并将其存储在数据库中，同时显示相同的data from the database with $ symbols in the same cells。看看它，它可能会有用。

只需根据需要更改代码。
