英文:
I can't read some Excel files with ClosedXML package in .NET
问题
private List<Dictionary<string, object>> ReadExcelData(IFormFile file)
{
using (var stream = file.OpenReadStream())
{
using (var workbook = new XLWorkbook(stream))
{
....
}
}
}
在 using (var workbook = new XLWorkbook(stream)) 这行代码中，我遇到了一个错误。我的 "file" 对象不为空。但是在这行代码中，它给了我 System.IO.FileFormatException: '文件包含损坏的数据。' 错误。
我尝试读取 Excel1.xls 文件，它能够正常工作，但当我尝试读取 Excel2.xls 文件时，它给了我这个错误。我进行了比较，它们的编码标准都是相同的，都是 ANSI。我将 .xls 更改为 .xlsx，但仍然不起作用。文件并没有损坏。我找不到任何解决方法。
提前谢谢

In using (var workbook = new XLWorkbook(stream)) line, I have an error. My "file" object is not empty. But on that line, it gives me System.IO.FileFormatException: 'File contains corrupted data.' error.
I am trying to read Excel1.xls file, it reads very well but when I try to read Excel2.xls file, it gives me this error. I compared them, their coding standarts are same, ANSI. I changed .xls with .xlsx. Still Excel1 file works, other not. Files are not corrupted. I couldnt't find any solution.
Thanks in advance

ClosedXML不支持旧式的.xls文件，只支持Excel 2007+的.xlsx和.xlsm文件。你需要另一个库，比如NPOI来读取.xls文件。
英文:
ClosedXML doesn't support old school .xls files, but only Excel 2007+ .xlsx and .xlsm files. You'll need another library, e.g. NPOI to read .xls.
