  根据这个类似的问题：“Saving a word document as an image”你可以这样做：

  const string basePath = @"C:\Users\SomeUser\SomePath\";
  var docPath = Path.Combine(basePath, "documentA.docx");
  var app = new Application()
                  {
                      Visible = true
                  };
  
  var doc = app.Documents.Open(docPath);
  
  foreach (Window window in doc.Windows)
  {
      foreach (Pane pane in window.Panes)
      {
          for (var i = 1; i <= pane.Pages.Count; i++)
          {
              var page = pane.Pages[i];
              var bits = page.EnhMetaFileBits;
              var target = Path.Combine(basePath, string.Format("page-no-{0}", i));
  
              using (var ms = new MemoryStream(bits))
              {
                  var image = Image.FromStream(ms);
                  var pngTarget = Path.ChangeExtension(target, "png");
                  image.Save(pngTarget, ImageFormat.Png);
              }
          }
      }
  }
  
  app.Quit();
  

  基本上，我正在使用 Page.EhmMetaFileBits 属性，根据documentation：

  返回一个Object，表示文本页面如何显示的图片表示 .

  ...并基于此，我创建一个图像并将其保存到磁盘 .
