c# – 在word文档中加载在线图像

我开发了一个wpf应用程序,只需将图像插入word文档.每次打开word文档时,我都希望图片从服务器调用图像,例如(server.com/Images/image_to_be_insert.png)
我的代码如下：

 Application application = new Application();
 Document doc = application.Documents.Open(file);

 var img = doc.Application.Selection.InlineShapes.AddPicture("server.com/Images/img.png");
 img.Height = 20;
 img.Width = 20;

 document.Save();
 document.Close();

基本上我的代码是什么,下载图像然后将其添加到文档.我想要做的是,我希望每当打开word文档时从服务器加载图像.

解决方法:

您可以使用新的OpenXML SDK来实现此目的,而不需要使用Office Interop库,而不需要安装MS Office才能工作.

要求

从Visual Studio安装OpenXML NuGet：DocumentFormat.OpenXml

添加所需的命名空间：

using DocumentFormat.OpenXml;
using DocumentFormat.OpenXml.Packaging;
using DocumentFormat.OpenXml.Vml;
using DocumentFormat.OpenXml.Wordprocessing;

代码

using (WordprocessingDocument package = WordprocessingDocument.Create(@"c:/temp/img.docx", WordprocessingDocumentType.Document))
{
    package.AddMainDocumentPart();

    var picture = new Picture();
    var shape = new Shape() { Style="width: 272px; height: 92px" };
    var imageData = new ImageData() { RelationshipId = "rId1" };
    shape.Append(imageData);
    picture.Append(shape);

    package.MainDocumentPart.Document = new Document(
        new Body(
            new Paragraph(
                new Run(picture))));

            package.MainDocumentPart.AddExternalRelationship("http://schemas.openxmlformats.org/officeDocument/2006/relationships/image",
   new System.Uri("https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png", System.UriKind.Absolute), "rId1");

    package.MainDocumentPart.Document.Save();
}

这将创建一个新的Word文档,该文档将在打开时从提供的URL加载Google徽标.
