Question

我想使用以下代码填充位于我的word文档的标题中的图片内容控件:(我已将内容控制标记和图像流通过文档参数传递给此函数）

 ImagePart ip = (ImagePart)idpp.OpenXmlPart;

它在word文档中找到内容控件，但是在这一行中：

navigator.userAgent;

我收到此错误：

无法投射类型的对象输入'DocumentFormat.OpenXml.Packaging.CustomXmlPart' “DocumentFormat.OpenXml.Packaging.ImagePart”。

你能指导我吗？

我试图找到一种方法，这是答案：

public void FillDocument(Stream stream, XDocument document)
    {    

using (WordprocessingDocument wordDocument =
            WordprocessingDocument.Open(stream, true))
        {
            List<SdtElement> descendants = wordDocument.MainDocumentPart.Document.Descendants<SdtElement>().ToList();
            foreach (HeaderPart headerPart in wordDocument.MainDocumentPart.HeaderParts)
            {
                descendants.AddRange(headerPart.Header.Descendants<SdtElement>().ToList());
            }
            foreach (var footerPart in wordDocument.MainDocumentPart.FooterParts)
            {
                descendants.AddRange(footerPart.Footer.Descendants<SdtElement>().ToList());
            }

            XDocument doc = document;


            foreach (SdtElement item in descendants)
            {
                SdtAlias alias = item.Descendants<SdtAlias>().FirstOrDefault();

                if (alias != null)
                {
                    string sdtTitle = alias.Val.Value;

                    //if Sdt Content Control is Picture
                    string imageContent = (from xElement in doc.Descendants("Picture") where xElement.Attribute("Id").Value == sdtTitle select xElement.Value).FirstOrDefault();
                    if (imageContent != null)
                    {
                        MemoryStream result = (MemoryStream)StringToStream(imageContent);

                        D.Blip blipElement = item.Descendants<D.Blip>().FirstOrDefault();
                        string imageId = "default value";

                        if (blipElement != null)
                        {
                            imageId = blipElement.Embed.Value;

                            ImagePartType imagePartType = ImagePartType.Png;

                            //Add image and change embeded id.
                            ImagePart imagePart = null;
                            Type p = item.Parent.GetType();
                            switch (p.Name)
                            {
                                case "Header":
                                    HeaderPart headerPart = ((Header)(item.Parent)).HeaderPart;
                                    imagePart = headerPart.AddImagePart(imagePartType);
                                    imagePart.FeedData(result);
                                    blipElement.Embed = headerPart.GetIdOfPart(imagePart);
                                    break;
                                case "Body":
                                    MainDocumentPart mainDocumentPart = wordDocument.MainDocumentPart;
                                    imagePart = mainDocumentPart.AddImagePart(imagePartType);
                                    imagePart.FeedData(result);
                                    blipElement.Embed = mainDocumentPart.GetIdOfPart(imagePart);
                                    break;
                                case "Footer":
                                    FooterPart footerPart = ((Footer)(item.Parent)).FooterPart;
                                    imagePart = footerPart.AddImagePart(imagePartType);
                                    imagePart.FeedData(result);
                                    blipElement.Embed = footerPart.GetIdOfPart(imagePart);
                                    break;
                                default:
                                    break;
                            }

                        }
                        continue;
                    }
            }

        }

   }}

它工作正常，可以在页眉或页脚或正文中填充图片内容控件！

使用OpenXML在word doc的标题中填充图片内容控件
