Extract attachments from PDF portfolios

To extract attachments from emails GetContainer method is used. This method returns the collection of ContainerItem objects.

Here are the steps to extract an attachment text from PDF Portfolios:

  • Instantiate Parser object for the initial document;
  • Call GetContainer method and obtain collection of ContainerItem objects;
  • Check if collection isn’t null (container extraction is supported for the document);
  • Iterate through the collection and get container item names, sizes and obtain content.

The following example shows how to extract a text from PDF Portfolios:

// Create an instance of Parser class
using(Parser parser = new Parser(filePath))
    // Extract attachments from the container
    IEnumerable<ContainerItem> attachments = parser.GetContainer();
    // Check if container extraction is supported
    if(attachments == null)
        Console.WriteLine("Container extraction isn't supported");

    // Iterate over attachments
    foreach(ContainerItem item in attachments)
		// Print the file path
            // Create Parser object for the email content
            using (Parser attachmentParser = item.OpenParser())
                // Extract an email text
                using (TextReader reader = attachmentParser.GetText())
                    Console.WriteLine(reader == null ? "No text" : reader.ReadToEnd());
        catch (UnsupportedDocumentFormatException)
            Console.WriteLine("Isn't supported.");
