如何使用OpenXml 2.0将任何文件类型嵌入到Microsoft Word中

using (WordprocessingDocument wordDoc = WordprocessingDocument.Open(docxFile, true))
{
    MainDocumentPart mainPart = wordDoc.MainDocumentPart;

    // 将PDF文件转换为OpenXml格式
    byte[] pdfBytes = File.ReadAllBytes(pdfFile);
    AlternativeFormatImportPart afiPart = mainPart.AddAlternativeFormatImportPart(
        AlternativeFormatImportPartType.Pdf, mainPart.GetIdOfPart(mainPart.Document));
    using (MemoryStream ms = new MemoryStream(pdfBytes))
    {
        afiPart.FeedData(ms);
    }

    // 创建嵌入式包含部分
    EmbeddedPackagePart packagePart = mainPart.AddEmbeddedPackagePart(afiPart.ContentType);
    using (FileStream fs = new FileStream(pdfFile, FileMode.Open))
    {
        packagePart.FeedData(fs);
    }

    // 创建嵌入式对象
    OpenXmlUnknownElement unknownElement = afiPart.CreateElement(new OpenXmlQualifiedName("o:OLEObject", "urn:schemas-microsoft-com:office:office"));
    unknownElement.SetAttribute(new OpenXmlQualifiedName("Type", ""), "Embed");
    unknownElement.SetAttribute(new OpenXmlQualifiedName("ProgID", ""), "AcroExch.Document.11");
    unknownElement.SetAttribute(new OpenXmlQualifiedName("ShapeID", ""), "_x0000_t129");
    unknownElement.SetAttribute(new OpenXmlQualifiedName("DrawAspect", ""), "Icon");
    unknownElement.SetAttribute(new OpenXmlQualifiedName("ObjectID", ""), "_1294302452");

    // 将嵌入式对象添加到文档中
    Paragraph p = new Paragraph();
    Run r = new Run();
    Drawing d = new Drawing();
    d.Append(unknownElement);
    r.Append(d);
    p.Append(r);
    mainPart.Document.Body.Append(p);
}
