Hello,

Do you want to add a table of content? I am bit confused at this point of adding a catalog.
If so, please try the below code:

Code: Select all

 Spire.Doc.Section sec = doc.Sections[0];

    sec.Paragraphs.Insert(0, para);
    para.AppendTOC(1, 3);


If not, could you please elaborate your requirement to help us know it? Thank you.

Thank you ,it works !But what is the meaning by "para.AppendTOC(2, 4);"?

[caroline.zhang]

Hello,

Thanks for your inquiry.
Firstly, glad that the code works for your scenario.
Then the method para.AppendTOC() contained two pramaters which represent lowerLevel and upperLevel. The lowerLevel is the starting heading level of table of content, and the upper level is the ending heading level of the table of content. Because the heading level starts from Heading 2 to Heading 4 in your docx file, so it should be “para.AppendTOC(2,4)”.

Thank you .It works .But could you explain the code "toc.Owner.Owner.Owner",so many owners confused me.

[caroline.zhang]

Hi,

OK, please refer to the below code with explanations

Code: Select all

            TableOfContent toc = doc.TOC; //defines a field as table of content
            var para = toc.Owner;        //Gets Toc Paragraph in the doc
            var con = para.Owner;        //Gets SDTContent of toc paragraph
            var tocObject = con.Owner;  //Gets StructureDocumentTag of the content
