Get document info

GroupDocs.Conversion allows to get basic document information (like pages count) for every supported document type, which may be useful for converting part of source document or per-page conversion.
Along with this GroupDocs.Conversion provides additional information for the following document types:

  • CAD drawings - collection of layouts and layers;
  • Email - attachments count, is html body, is encrypted, is signed;
  • PDF document - pages count, is landscaped, is encrypted, author and creation date;
  • Image - width, height, image format;
  • Presentation document - slides count, author, creation date and presentation format;
  • Spreadsheet document - worksheets count, author and creation date;
  • Wordprocessing document - pages count, lines count, words count, author and creation date.

Here is a code snippet to demonstrate how to obtain document info for PDF document.

using (Converter converter = new Converter("sample-toc.pdf"))
{
    IDocumentInfo info = converter.GetDocumentInfo();
    PdfDocumentInfo pdfInfo = (PdfDocumentInfo) info;
    Console.WriteLine("Author: {0}", pdfInfo.Author);
    Console.WriteLine("Creation date: {0}", pdfInfo.CreationDate);
    Console.WriteLine("Title: {0}", pdfInfo.Title);
    Console.WriteLine("Version: {0}", pdfInfo.Version);
    Console.WriteLine("Pages count: {0}", pdfInfo.PagesCount);
    Console.WriteLine("Width: {0}", pdfInfo.Width);
    Console.WriteLine("Height: {0}", pdfInfo.Height);
    Console.WriteLine("Is landscaped: {0}", pdfInfo.IsLandscape);
