How do I add structured content to a Word Document via Interop (C#)?

Thanks for looking. I am writing some C# to create a word doc based on a dataset. Using Microsoft.Office.Interop.Word I am able to create a document with formatted headings for the sections, but there is no associated structure. In other words, I can't see my sections in the Navigation pane or generate a Table of Contents.

Here is what I am trying:

Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application();
Microsoft.Office.Interop.Word.Document document = WordApp.Documents.Add(ref missing, ref missing, ref missing, ref missing);

document.Range(0, 0);

foreach (var solutionModel in solutions)
{
    var hText = document.Paragraphs.Add();
    hText.Format.SpaceAfter = 10f;
    hText.set_Style(Microsoft.Office.Interop.Word.WdBuiltinStyle.wdStyleHeading1);
    hText.Range.Text = solutionModel.Name;
    hText.Range.InsertParagraphAfter();

    var pText = document.Paragraphs.Add();
    pText.Format.SpaceAfter = 50f;
    pText.set_Style(Microsoft.Office.Interop.Word.WdBuiltinStyle.wdStyleNormal);
    pText.Range.Text = "Lorem ipsum dolor sit amet.";
    pText.Range.InsertParagraphAfter();
}

WordApp.Visible = true;

This renders nicely in Word with the headings (hText) taking on the native Header 1 style, but there is no associated structure.

Initially I was thinking the same as @Dirk mentioned in the comments, but tested it and as you've seen yourself that didn't work in your code.

After doing some more research I found that my other answer actually did not result in having the right Header Style applied to your added paragraphs. So my testing resulted in the following outcome:

You need to set the text before applying the style.

var hText = document.Paragraphs.Add();

hText.Range.Text = solutionModel.Name; // <--

hText.set_Style(Microsoft.Office.Interop.Word.WdBuiltinStyle.wdStyleHeading1);
hText.Format.SpaceAfter = 10f;
hText.Range.InsertParagraphAfter();

I added two empty rows to bring attention to the position of the Text line location, but you can leave that out.

You can set the OutlineLevel (that is located on the ParagrapFormat of a Paragraph's Range) to the desired level (VBA):

ActiveDocument.Paragraphs(1).Range.ParagraphFormat.OutlineLevel = wdOutlineLevel1

In your case (C#):

hText.Range.Text = solutionModel.Name;
hText.Range.ParagraphFormat.OutlineLevel = Microsoft.Office.Interop.Word.WdOutlineLevel.wdOutlineLevel1;

This will add the selected paragraph to the Navigation View
