Safest way to copy a file
- by aron
Hello,
I need to merg two PDF files.
However sometimes a file might be locked up
I wrote this code, but I'm wondering if it's not the smartest solution:
private static int FILE_LOCKED_WAIT_PERIOD = 1000;
while (true)
{
// If the file is in use, IOException will be thrown.
// If file is not permitted to be opened because of Permission
// Restrictions, UnauthorizedAccessException will be thrown.
// For all other, Use normal Exception.
try
{
inputDocument1 = PdfReader.Open(fileToMerge, PdfDocumentOpenMode.Import);
break;
}
catch (IOException)
{
Thread.Sleep(FILE_LOCKED_WAIT_PERIOD);
}
catch (UnauthorizedAccessException)
{
Thread.Sleep(FILE_LOCKED_WAIT_PERIOD);
}
catch (Exception)
{
Thread.Sleep(FILE_LOCKED_WAIT_PERIOD);
}
}
