寻找一种方法，在word文档中使用open xml将可折叠功能应用于标题。

Question

我试图在生成word文档时，用下面的代码来渲染标题部分。

    private static Paragraph BuildSubHeaderPart(string headingText)
    {
        Paragraph headerParagraph = new Paragraph();

        var runProperty = new RunProperties();

        runProperty.Append(new RunFonts() { Ascii = "Nirmala UI", HighAnsi = "Nirmala UI" }
            , new FontSize { Val = new StringValue("22") }
            , new Bold()
            , new Color() { Val = "55B6DA" });
        runProperty.Append(new Text(headingText) { Space = SpaceProcessingModeValues.Default });
        headerParagraph.AppendChild(new Run()).Append(runProperty);

        return headerParagraph;
    }

将标题添加到正文中，如下所示

  var mainDocumentPart = wordDoc.AddMainDocumentPart();
  Document doc = new Document();
  mainDocumentPart.Document = doc;
  doc.Body = new Body();

  Body body = wordDoc.MainDocumentPart.Document.Body;
  body.AppendChild(BuildSubHeaderPart("MECHANICAL SYSTEMS"));

这是很好的工作，现在我正在寻找方式来应用 collapsible/Expand 使用c#代码为这个标题添加功能，如下图所示。

有什么办法可以实现这个功能，我是用Open XML与.Net Core来生成word文档的。

能否有人对这个问题提出任何建议，非常感谢。

更新代码。

  Paragraph headerParagraph = new Paragraph();
        ParagraphProperties paragraphProperties1 = new ParagraphProperties();
        OpenXmlUnknownElement openXmlUnknownElement1 = OpenXmlUnknownElement.CreateOpenXmlUnknownElement("<w15:collapsed xmlns:w15=\"http://schemas.microsoft.com/office/word/2012/wordml\" />");
        paragraphProperties1.Append(openXmlUnknownElement1);
        var runProperty = new RunProperties();
        runProperty.Append(new RunFonts() { Ascii = "Nirmala UI", HighAnsi = "Nirmala UI" }
            , new FontSize { Val = new StringValue("22") }
            , new Bold()
            , new Color() { Val = "55B6DA" });
        runProperty.Append(new Text(headingText) { Space = SpaceProcessingModeValues.Default });
        headerParagraph.Append(paragraphProperties1);
        headerParagraph.AppendChild(new Run()).Append(runProperty);

你应该可以对一个段落使用这样的代码，但是如果你想让一个段落的所有段落都能使用这样的代码。风格 要折叠，你将需要使用类似的代码来修改样式。

ParagraphProperties paragraphProperties1 = new ParagraphProperties();


// having the level makes it collapsible
// You'll need to change the level as appropriate in { Val = 1 }
// so either you'll need to pass an outline level parameter to your
// method and set the level (or no level) 
//or perhaps have a second method to add these outline level paras.
OutlineLevel outlineLevel1 = new OutlineLevel() { Val = 1 };


//Having the w15:collapsed element makes the show as
// collapsed when you open the document.
// if you want it expanded on open, do not add
// this element
OpenXmlUnknownElement openXmlUnknownElement1 = OpenXmlUnknownElement.CreateOpenXmlUnknownElement("<w15:collapsed xmlns:w15=\"http://schemas.microsoft.com/office/word/2012/wordml\" />");
paragraphProperties1.Append(outlineLevel1);
paragraphProperties1.Append(openXmlUnknownElement1);
headerParagraph.Append(paragraphProperties);

顺便说一下，我认为你在这里描述的是一个。标题. 在Word中，a 头部 是指页面顶部的区域(以 页脚 (在底部)]
