DocumentInfo

DocumentInfo class

Provides read-only metadata about a loaded document, such as its format, page count, title, and encryption status.

public class DocumentInfo

Properties

Name Description
Author { get; } Gets the document author extracted from its metadata, or Empty if no author is available.
FileFormat { get; } Gets the detected file format of the document.
IsEncrypted { get; } Gets a value indicating whether the document is password-protected.
PageCount { get; } Gets the number of pages in the document. For spreadsheets this returns the number of worksheets.
Title { get; } Gets the document title extracted from its metadata, or Empty if no title is available.

Remarks

Use GetDocumentInfo or GetInfo to obtain an instance of this class. The information is extracted from the source document without performing a full conversion, so it is a lightweight way to inspect a file before converting it.

Examples

Inspect a document before converting it:

// Using the static helper
DocumentInfo info = MarkdownConverter.GetInfo("report.docx");
Console.WriteLine($"Format: {info.FileFormat}");
Console.WriteLine($"Pages:  {info.PageCount}");
Console.WriteLine($"Title:  {info.Title}");
Console.WriteLine($"Author: {info.Author}");

if (info.IsEncrypted)
    Console.WriteLine("The document is password-protected.");

Using the instance method:

using (var converter = new MarkdownConverter("spreadsheet.xlsx"))
{
    DocumentInfo info = converter.GetDocumentInfo();
    Console.WriteLine($"Worksheets: {info.PageCount}");
}
