SubDocument.InsertDocumentContent(DocumentPosition, Stream) Method
Inserts content from the stream in the current document at the specified position.
A DocumentPosition specifying the position in the current document, after which content is inserted.
A Stream representing a sequence of bytes interpreted as the content to insert.
A DocumentRange representing the document range with inserted content.
The InsertDocumentContent method loads the specified stream into the internal document model with the help of the specific importer.
After the stream is imported successfully, the new document model is inserted at the specified position of the main document.
The inserted text starts with a new paragraph and preserves formatting. It is inserted into an existing section and gets all section details (header, footer, page and print layout).
If the text being inserted contains document styles which are not present in the current document, the styles are copied to the resulting document.
If the document whose content is being inserted contains floating objects, such as pictures or text boxes, they are inserted into the corresponding positions in a newly created range.
The inserted content's format is determined automatically.
