PdfDocument.Merge Method (String, String, Int32)

Merges two PDF files.

Syntax
C#
Copy
 public static void Merge(
   string fileName1,
   string fileName2,
   int bookmarkLevel
);

Parameters

fileName1
Full path of the first PDF file.
fileName2
Full path of the second PDF file.
bookmarkLevel
Specify on which level the second file's bookmarks should be inserted into. See remark section for more details.
Remarks

This function appends the second PDF file to the end of the first PDF file and does not perform a "deep merge". thus can result in bigger file but uses less memory and is much faster.

If either of the source file has bookmarks, then they will be merged into the final file. In case both file has bookmarks, it may be necessary to insert the second file's bookmarks as child bookmarks of a bookmark item in the first file. For example, consider the following bookmark structure:

The first file's bookmarks:

Chapter 1 - Overview Introduction Terms and definitions Chapter 2 - Syntax

The second file's bookmarks:

File Structure Object Types Members

If the desired final bookmarks is:

Chapter 1 - Overview Introduction Terms and definitions Chapter 2 - Syntax File Structure Object Types Members

Then bookmarkLevel should be set to 1, which indicating the second file's bookmarks will be on the second level (0 based).

If bookmarkLevel is set to 0, then all bookmarks for the second file will be directly appended after "Chapter 2":
