c# - 如何使用 Open XML SDK 将 Word 文档 (docx) 中的书签替换为图像？

Question

我需要一个带有一组书签的模板 Word 文档，并将它们替换为图像(删除书签本身)。我看到的使用书签的示例令人困惑，我不确定它们是否适用于使用 ImagePart，因为看起来情况因内容而异。

谁能提供一个简单的例子？

您可以使用下面的方法 ReplaceBookmarksWithImage 将所有书签替换为给定的图像。 word模板文件路径和图片文件路径为参数。如果每个书签需要不同的图像，您可以扩展代码。

    private static void ReplaceBookmarksWithImage(string wordDocTempaltePath, string imageFilename)
    {
        WordprocessingDocument doc = WordprocessingDocument.Open(wordDocTempaltePath, true);

        // Read all bookmarks from the word doc
        foreach (BookmarkStart bookmarkStart in doc.MainDocumentPart.RootElement.Descendants<BookmarkStart>())
        {
            // insert the image
            InsertImageIntoBookmark(doc, bookmarkStart, imageFilename);

            // remove the bookmark
            bookmarkStart.Remove();
        }

        doc.Close();
    }

    public static void InsertImageIntoBookmark(WordprocessingDocument doc, BookmarkStart bookmarkStart, string imageFilename)
    {
        // Remove anything present inside the bookmark
        OpenXmlElement elem = bookmarkStart.NextSibling();
        while (elem != null && !(elem is BookmarkEnd))
        {
            OpenXmlElement nextElem = elem.NextSibling();
            elem.Remove();
            elem = nextElem;
        }

        // Create an imagepart
        var imagePart = AddImagePart(doc.MainDocumentPart, imageFilename);

        // insert the image part after the bookmark start
        AddImageToBody(doc.MainDocumentPart.GetIdOfPart(imagePart), bookmarkStart);
    }

    public static ImagePart AddImagePart(MainDocumentPart mainPart, string imageFilename)
    {
        ImagePart imagePart = mainPart.AddImagePart(ImagePartType.Jpeg);

        using (FileStream stream = new FileStream(imageFilename, FileMode.Open))
        {
            imagePart.FeedData(stream);
        }

        return imagePart;
    }

    private static void AddImageToBody(string relationshipId, BookmarkStart bookmarkStart)
    {
        // Define the reference of the image.
        var element =
            new Drawing(
                new DW.Inline(
                    new DW.Extent()
                        {
                            Cx = 990000L,
                            Cy = 792000L
                        },
                    new DW.EffectExtent() { LeftEdge = 0L, TopEdge = 0L, RightEdge = 0L, BottomEdge = 0L },
                    new DW.DocProperties() { Id = (UInt32Value)1U, Name = "Picture 1" },
                    new DW.NonVisualGraphicFrameDrawingProperties(new A.GraphicFrameLocks() { NoChangeAspect = true }),
                    new A.Graphic(
