What steps will reproduce the problem?
1. Try to open a non-Excel file(e.g. a comma delimited file using xls
extension.)
2. Handle the ArgumentOutOfRangeException
3. Try to open the same file by using Stream class
What is the expected output? What do you see instead?
The CompoundDocument.Open method throws an ArgumentOutOfRangeException but it
do not release the loaded file in the Open method. Therefore, when trying to
open the same file using Stream class, I see the exception:
IOException: The process cannot access the file 'filename' because it is being
used by another process
I would expect a null value as output.
What version of the product are you using? On what operating system?
FileName: ExcelLibrary.dll
Release Date: Jul 2011

WORKAROUND:
public static CompoundDocument Open(string file)
{
FileStream stream = File.Open(file, FileMode.Open, FileAccess.ReadWrite, FileShare.Read);
BinaryReader reader = new BinaryReader(stream);
FileHeader header = ReadHeader(reader);
int sectorSize = (int)Math.Pow(2, header.SectorSizeInPot);
CompoundDocument document = null;
if (sectorSize > 0)
{
document = new CompoundDocument(stream, header);
if (!document.CheckHeader()) return null;
document.ReadDirectoryEntries();
}
else
{
stream.Close();
stream.Dispose();
reader.Close();
}
return document;
}
