我从供应商处收到一个 .xlsx 文件，它包含一个 HH:mm:ss 格式的持续时间列，当我在 Excel 中打开文件时，它显示为日期，但实际上应该只是一个字符串。
我想使用 ExcelDataReader 将此 .xslx 文件读入我的 c# 应用程序，而无需在运行我的应用程序之前手动修改或删除该列。
FileStream fs = File.Open(extractedFilePath, FileMode.Open, FileAccess.Read);
var reader = ExcelReaderFactory.CreateReader(fs);
//I've also tried using ExcelReaderFactory.CreateOpenXmlReader(fs) and get the same error
但是，当我尝试按上述方式创建阅读器时，出现以下错误：
System.FormatException: String was not recognized as a valid DateTime.
at System.DateTimeParse.ParseExact(String s, String format, DateTimeFormatInfo dtfi, DateTimeStyles style)

有没有办法解决这个错误？
