OpenXML 添加图像在 Document 媒体文件夹中但不显示在 Office 中

Question

我在创建 Word 文档 (openXML) 和向其中添加图像时遇到问题。我已经尝试了很多我发现的代码片段以及官方 MS 文档 (https://docs.microsoft.com/de-de/office/open-xml/how-to-insert-a-picture-into-a-word-processing-document)。

为了让它正常工作，我基本上从上面的 Link 复制了完整的代码，并包装了 2 个 WPF FileDialogs 以首先创建一个文档，然后选择要添加的图像。我还在图像前添加了一些文本，以检查访问文档是否正常。

一切都编译和运行没有错误。但是，创建的文档只有我的文字，没有图像的迹象。我经常读到有人遇到诸如“红色 X”之类的错误或缺少添加图像的资源的某些迹象，但对我而言，该文档只包含添加的文本。但是，当我将文档作为存档打开时（例如使用 winrar），我可以看到我选择的图像位于我的文档的“媒体”文件夹中。

为什么我用office打开文档没有任何显示？

下面是我的代码，但它基本上来自官方 SDK：

using A = DocumentFormat.OpenXml.Drawing;
using DW = DocumentFormat.OpenXml.Drawing.Wordprocessing;
using PIC = DocumentFormat.OpenXml.Drawing.Pictures;    

public static void ExportToDoc()
    {
        
        SaveFileDialog exportFile = new SaveFileDialog
        {
            Filter = "Word Document (*.docx)|*.docx",
            AddExtension = true,
            FileName = "Proposed-Filename.docx"
        };
        switch (exportFile.ShowDialog())
        {
            case true:
                WordprocessingDocument doc = WordprocessingDocument.Create(exportFile.FileName, WordprocessingDocumentType.Document);
                // Make some changes to the document.  
                MainDocumentPart mainDocumentPart = doc.AddMainDocumentPart();
                mainDocumentPart.Document = new Document();
                Document document = mainDocumentPart.Document;
                Body body = document.AppendChild(new Body());
                Paragraph para = body.AppendChild(new Paragraph());
                Run run = para.AppendChild(new Run());
                run.AppendChild(new Text("Created text in body."));

                //Prepare Image
                OpenFileDialog openImage = new OpenFileDialog
                {
                    Filter = "Bild (*.jpg)| *.jpg"
                };
                
                //Document is created
                doc.Close();

                switch (openImage.ShowDialog())
                {
                    case true:

                     EditId = "50D07946"
                 });

        // Append the reference to body, the element should be in a Run.
        wordDoc.MainDocumentPart.Document.Body.AppendChild(new Paragraph(new Run(element)));
    }

}

Answer 1

好的，我自己想出来了：

我为绘图使用了错误的命名空间。就是这样。

有趣的是，这根本没有产生任何错误，但却不起作用。

因此，如果您遇到此问题，这就是我所做的更改：

 private static void AddImageToBody(WordprocessingDocument wordDoc, string relationshipId)
        {
            // Define the reference of the image.
            var element =
                 new DocumentFormat.OpenXml.Office.Drawing.Drawing(

更改为：

private static void AddImageToBody(WordprocessingDocument wordDoc, string relationshipId)
            {
                // Define the reference of the image.
                var element =
                     new DocumentFormat.OpenXml.Wordprocessing.Drawing(
