保存在word文档openXML

Question

我阅读了一些与构建文档相关的文档，因此我使用构建块构建我的应用程序，其中每个块都是一个组件（标题，图像......）。

因此，当我构建我的doc结构时，我有类似的东西：

DocRun accessTypeTitle  = new DocRun();
Run permissionTitle = accessTypeTitle.createParagraph("DOCUMENT ACCESS", "0475B9","16");

// document permission (ex: public, internal use only), defined on template side
DocRun accessTypePermission = new DocRun();
Run permission = accessTypePermission.createParagraph(document.documentAccess, "262626", "16");

DocRun disclaimerTitle = new DocRun();
Run disclaimerTitleTxt = disclaimerTitle.createParagraph("DISCLAIMER", "0475B9", "16");

DocRun disclaimerDescription = new DocRun();
Run disclaimerDescriptionTxt = disclaimerDescription.createParagraph(disclaimerTxt, "262626", "16");

var stream = new MemoryStream();
using (WordprocessingDocument doc = WordprocessingDocument.Create(stream, WordprocessingDocumentType.Document, true))
{
    MainDocumentPart mainPart = doc.AddMainDocumentPart();

    new Document(new Body()).Save(mainPart);

    Body body = mainPart.Document.Body;

    /*body.Append(new Paragraph(
             new Run(image)));*/

    body.Append(new Paragraph(
               new Run(permissionTitle)));

    body.Append(new Paragraph(
              new Run(permission)));

    body.Append(new Paragraph(
             new Run(disclaimerTitleTxt)));

    body.Append(new Paragraph(
             new Run(disclaimerDescriptionTxt)));

    mainPart.Document.Save();
}

我有一个处理这些功能的外部dll，我需要为我的图像提供相同的功能。

基本上，图像应该是文档中添加的第一件事，我看到一些文档，他们访问uri并将图像保存在路径上。我只需要访问我的图像文件夹获取图像并将其添加到文档中。

目前我有这个：

DocImage docImage = new DocImage();
Drawing image = docImage.addImage("2", "https://pbs.twimg.com/profile_images/465786286825955328/JIN8xseJ_400x400.png");

namespace openXml
{
    public class DocImage
    {

        public Drawing addImage(String relationshipId,String uri)
        {
            // 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(
                             new A.GraphicData(
                                 new PIC.Picture(
                                     new PIC.NonVisualPictureProperties(
                                         new PIC.NonVisualDrawingProperties()
                                         {
