Class PdfMetadata

Namespace

DocToolkit

Assembly

DocToolkit.dll

The document information a PDF carries about itself — what a file manager shows in its properties panel, and what a search indexer reads.

Remarks

Every property is nullable, and null means absent rather than blank. The distinction matters to anything combining metadata from more than one source: an absent title should be replaced by a fallback, while a deliberately empty one should not.

WithMetadata(byte[], PdfMetadata) applies the same rule in the other direction — a null property leaves whatever the document already had alone, so stamping a title does not silently erase an author.
