使用OpenXML SDK C＃以编程方式将FootNotes添加到Word文档

Question

I need to create a Word Document using Open XML SDK. I have the document text and the Footnotes . I am using the below Snippets to Create the Word Document. I am able to create the document with the text ,But I am not able to add Footnotes to it. Can you please let us know how to add FootNotes programmatically using Open Xml

   public void CreateWordDocument()
   {

       using (MemoryStream DocxMemory = new MemoryStream())
       {
           using (WordprocessingDocument wordDocument = WordprocessingDocument.Create(DocxMemory, WordprocessingDocumentType.Document, true))
           {
               // Add a main document part. 
               MainDocumentPart mainPart = wordDocument.AddMainDocumentPart();
               // Create the document structure and add some text.
               this.AddSettingsToMainDocumentPart(mainPart);

               StyleDefinitionsPart part = mainPart.StyleDefinitionsPart;
               // If the Styles part does not exist, add it.  
               if (part == null)
               {
                   this.AddStylesPartToPackage(mainPart);
               }

               mainPart.Document = new Document();
               Body body = mainPart.Document.AppendChild(new Body());

Answer 1

I managed to add footnotes using the following code. I hope this helps.

        var ms = new MemoryStream();
        using (WordprocessingDocument myDoc = WordprocessingDocument.Create(ms, WordprocessingDocumentType.Document))
        {
            MainDocumentPart mainPart = myDoc.AddMainDocumentPart();
            var footPart = mainPart.AddNewPart<FootnotesPart>();
            footPart.Footnotes = new Footnotes();

            mainPart.Document = new Document();
            Body body = new Body();
            var p = new Paragraph();
            var r = new Run();
            var t = new Text("123");
            r.Append(t);
            p.Append(r);

            // ADD THE FOOTNOTE
            var footnote = new Footnote();
            footnote.Id = 1;
            var p2 = new Paragraph();
            var r2 = new Run();
            var t2 = new Text();
            t2.Text = "My FootNote Content";
            r2.Append(t2);
            p2.Append(r2);
            footnote.Append(p2);
            footPart.Footnotes.Append(footnote);

            // ADD THE FOOTNOTE REFERENCE
            var fref = new FootnoteReference();
            fref.Id = 1;
            var r3 = new Run();
            r3.RunProperties = new RunProperties();
            var s3 = new VerticalTextAlignment();
            s3.Val = VerticalPositionValues.Superscript;
            r3.RunProperties.Append(s3);
            r3.Append(fref);
            p.Append(r3);

            body.Append(p);
            mainPart.Document.Append(body);
            mainPart.Document.Save();
            ms.Flush();
        }
        return ms.ToArray();

I'm not an expert on OpenXML but I think you're missing adding an actual reference to the footnote in the body text, I tweaked your code like this and I now get the footnote in the document. Hope it helps or at least gets you started.

Run run = Para.AppendChild(new Run());
run.AppendChild(new DocumentFormat.OpenXml.Wordprocessing.Text("This is main text of the document"));
var footnoteref = new FootnoteReference() { Id = 1 };
run.Append(footnoteref);
