How to Add Footnote in Word by Using C#/VB.NET

Footnote which is always put at the end of one page and separated from contents, is additional information to explain some words or sentences in a Word document.

Generally speaking, if users want to explain one complicated word or show some additional description of one paragraph, they would like to add footnote because footnote will not influence integrity of original contents and help readers learn more information which is related to this document.

In this post, I want to introduce a method about how to add footnote in Word document by using C#/VB.NET. Also, Spire.Doc is used in this example for meeting my requirements more quickly and easily.

Steps

Step 1. Load Document

Use document.LoadFromFile() method to get document which I want to add footnote. Then, get the second paragraph in the first section. Note: title is paragraph 1.

C#

            Document document = new Document();

            document.LoadFromFile(@"E:\work\documents\Antarctic.docx");

            Section section = document.Sections[0];

            Paragraph paragraph = section.Paragraphs[1];

VB.NET

            Dim document As New Document()

            document.LoadFromFile("E:\work\documents\Antarctic.docx")

            Dim section As Section = document.Sections(0)

            Dim paragraph As Paragraph = section.Paragraphs(1)

Step 2. Add Footnote

Use paragraph.AppendFootnote() method to add footnote. The parameter is passed to this method is foot note type. Then, add footnote content by using footnote.TextBody.AddParagraph().AppendText() method. After that, set format for footnote content.

C#

            Footnote footnote=paragraph.AppendFootnote(FootnoteType.Footnote);

            TextRange text = footnote.TextBody.AddParagraph().AppendText("If you want to get more information of Antarctic, please check from wiki.");

            text.CharacterFormat.FontName = "Arial Narrow";

            text.CharacterFormat.FontSize = 12;

            text.CharacterFormat.TextColor = Color.SlateGray;

VB.NET

            Dim footnote As FootNote = paragraph.AppendFootnote(FootnoteType.Footnote)

            Dim text As TextRange = footnote.TextBody.AddParagraph().AppendText("If you want to get more information of Antarctic, please check from wiki.")

            text.CharacterFormat.FontName = "Arial Narrow"

            text.CharacterFormat.FontSize = 12

            text.CharacterFormat.TextColor = Color.SlateGray

Actually, footnote is formed with content and marker, which is often shown as number. In this step, I will set format for marker.

C#

            footnote.MarkerCharacterFormat.FontName = "Century Gothic";

            footnote.MarkerCharacterFormat.FontSize = 15;

            footnote.MarkerCharacterFormat.Bold = true;

            footnote.MarkerCharacterFormat.TextColor = Color.DarkCyan;

VB.NET

            footnote.MarkerCharacterFormat.FontName = "Century Gothic"

            footnote.MarkerCharacterFormat.FontSize = 15

            footnote.MarkerCharacterFormat.Bold = True

            footnote.MarkerCharacterFormat.TextColor = Color.DarkCyan

Step 3. Save and Launch

Save this document by using document.SaveToFile() method and then launch it for viewing.  

C#

            document.SaveToFile("FootNote.docx", FileFormat.Docx);

            System.Diagnostics.Process.Start("FootNote.docx");

VB.NET

            document.SaveToFile("FootNote.docx", FileFormat.Docx)

            System.Diagnostics.Process.Start("FootNote.docx")
