Hi,
I am trying to open a file using FileStream Object in C# and I am getting an
error: "
" Duplicate name " SummaryInformation" ". We are getting this file from our
client to parse the file and process the information in our system.
But one scenario, I have noticed that If I open this file using Microsoft excel
and at the time of closing, the excel is asking for save the file. If do no
changes in the file and just click save button(or Ctrl + S), then I am not
getting any error and the file is getting processed properly. Please find my
code and exception details below:
Code:
using (FileStream sourceStream = File.Open(filePath, FileMode.Open,
FileAccess.Read))
{
HSSFWorkbook Workbook = new HSSFWorkbook(sourceStream); // This statement
is throwing an exception
}
Exception Message: " Duplicate name " SummaryInformation" "
Exception Source: NPOI DLL
Target Site Name: PopulatePropertyTree
Please help me with a quick resolution for this.
Thanks In advance.
Regards,
Nilabhra Bhattacharjee
