I used Aspose PDF version 21.12.0 to load the input file. However, the process crashes during the file loading stage. Please help look into the cause of the crash and suggest a possible fix. Thank you very much.
Code:

using(var inputDocument = new Document(<input file>))
{
    foreach(Page page in inputDocument.Pages)
    {
        if(page == null)
        {
            continue;
        }
    }
}

It appears you are encountering a crash when loading a PDF file using Aspose PDF version 21.12.0. This issue may stem from several factors, including file corruption, compatibility issues, or memory limitations.

Here are some steps to troubleshoot and potentially resolve the issue:

  1. Check File Integrity: Verify that the PDF file is not corrupted. Open it with a standard PDF viewer to ensure it displays correctly.

  2. Update Aspose PDF: Consider upgrading to the latest version of Aspose PDF. Newer versions often include bug fixes and enhancements that may address your issue.

  3. Memory Management: If the PDF is large or complex, ensure your application has adequate memory allocated. Monitor memory usage during the loading process to identify any potential limitations.

  4. Error Handling: Implement error handling in your code to catch exceptions and log them. This can provide valuable insights into the cause of the crash.

Here’s an example of how to add error handling to your code:

try
{
    using (var inputDocument = new Document(<input file>))
    {
        foreach (Page page in inputDocument.Pages)
        {
            if (page == null)
            {
                continue;
            }
            // Process the page
        }
    }
}
catch (Exception ex)
{
    Console.WriteLine($"An error occurred: {ex.Message}");
}

If the problem persists after trying these steps, consider reaching out to the Aspose support forum with details about the issue, including specific error messages or behaviors you observe.
