Hi, I am facing issue with reading .xls and .xlsx file. It does work in my local machine. But, when published to QA box it throws the below error. Did anyone came across this issue ? I have pasted below the error stack trace for the reference.
My code :
FileOperation.FileStream stream = FileOperation.File.Open(path, FileOperation.FileMode.Open, FileOperation.FileAccess.ReadWrite);
IExcelDataReader excelReader = null;
if (fileType.FileExtension == "xls" && new List<string>() { "application/excel", "application/vnd.ms-excel", "application/x-excel", "application/x-msexcel" }.Contains(fileType.FileMimeType))
{
excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
}
else if (fileType.FileExtension == "xlsx" && fileType.FileMimeType == "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")
{
excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
}
excelReader.IsFirstRowAsColumnNames = false;
List<FeeScheduleLine> feeScheduleLines = new List<FeeScheduleLine>();
while (excelReader.Read())
{
}
Thanks in advance.
