It seems that when file creation is watched, the file copying/uploading is still in process. You need to wait for some time before starting a new ProcessDirectory(). e.g. waiting for 1 second: System.Threading.Thread.Sleep(1000);


private static void OnCreated(object sender, FileSystemEventArgs e)
    //string value = $"Created: {e.FullPath}";
    //Sleep some time to wait for the process of copying/uploading files is done

Thank you for your response…i will check.also i have some issues on conversion result…could you check and give some solution

Thanks for the sample files.

I evaluated your issue using one of your template file “#40168(2021)_検査報告書(目視).xlsx” to directly convert to PDF via Aspose.Cells APIs. In the output PDF file, I only noticed issue on the second page, the contents/data is actually part of first page which should be rendered on the first page. Could you confirm this is the only issue you are talking about? After your confirmation, I will log a separate ticket for the issue into our database.
Sample code:

    Workbook workbook = new Workbook("e:\\test2\\#40168(2021)_検査報告書(目視).xlsx");

exactly that was the problem…could you log a seperate ticket for the issue?
