Question

Footnotes have numbering restart options. Numbering can be restarted from: page, section or can be continuous.

How can I programmatically get numbering restart setting(s) for footnotes of an existing docx document.

Thank you for advices.

Answer 1

The document wide footnote settings can be found in the DocumentSettingsPart.
The releated class in the OpenXml SDK is called FootnoteDocumentWideProperties.

The sample below reads the footnote numbering restart settings configured by the user:

public static void ReadFootnoteNumberingRestartSettings()
{
  using (WordprocessingDocument wordDoc = 
         WordprocessingDocument.Open(@"c:\temp\Doc1.docx", true)) 
  {
    FootnoteDocumentWideProperties fdwp = 
             wordDoc.MainDocumentPart.DocumentSettingsPart.Settings.Elements<FootnoteDocumentWideProperties>().FirstOrDefault();

    if (fdwp == null)
    {
      Console.Out.WriteLine("No document wide footnote settings specified.");
      return;
    }

    if (fdwp.NumberingRestart == null)
    {
      Console.Out.WriteLine("No numbering restart settings specified.");
      return;
    }

    Console.Out.WriteLine("Numbering restart option: {0}", fdwp.NumberingRestart.Val);    
  }
}

static void Main(string[] args)
{
  ReadFootnoteNumberingRestartSettings();
}
