c#asp.net中从excel读取到数据库的外部表格式异常

问题是： 我从excel工作表将数据导入数据库的代码对于.xls很有效，但是对于.xlsx它给出了“外部表不是预期的格式。”错误

请帮我做这个

我使用的连接字符串是：

<add name="Excel03ConString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;  Data Source={0};Extended Properties='Excel 8.0;HDR={1}'"/>

<add name="Excel07ConString" connectionString="Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties='Excel 12.0;HDR={1}; IMEX=YES'"/>

问一个明显的问题，您确定.xls和.xlsx文件的列标题完全相同吗？即，列标题等中没有意外的额外空格。？如果标题名称与查询不匹配，则您收到的错误消息很常见。是的，它们是相同的。要问明显的问题，您确定.xls和.xlsx文件之间的列标题完全相同吗？即，列标题等中没有意外的额外空格。？如果标题名称与查询不匹配，则您收到的错误消息很常见。是的，它们是相同的。要问明显的问题，您确定.xls和.xlsx文件之间的列标题完全相同吗？即，列标题等中没有意外的额外空格。？如果标题名称与查询不匹配，则您收到的错误消息很常见。是的，它们是相同的
