存储从.DOC MS Word文件，与功放的数学方程;恢复它们 [英] Storing math equations from .doc MS Word file & restoring them

问题描述

我在处理含有数学公式和图像的Microsoft Word文件。
我需要得到这些 InlineShapes 对象，并将其储存的按原样&安培;需要的时候再恢复它们。

我知道如何让 InlineShape 从文件对象，问题是我怎么能存储它们。保存为图片是不是一种选择

解决方案

 使用系统！; 
使用System.Drawing中; 
：使用System.IO; 
使用的System.Threading;使用页面= System.Web.UI.Page 
; 
使用的Microsoft.Office.Interop.Word;使用Microsoft.VisualBasic.Devices 
; 
公共部分类ReadIMG：System.Web.UI.Page 
 {
私人应用m_word; 
私人诠释m_i; 
保护无效的Page_Load（对象发件人，EventArgs五）
 {
对象缺少= Type.Missing; 
目标文件名=使用Server.Mappath（〜/ LectureOrig / Word.docx）; 
对象readOnly的= TRUE; 
 m_word =新的应用程序（）; 
 m_word.Documents.Open（REF文件名，
裁判失踪，裁判只读，已参考失踪，失踪参考，
参考失踪，失踪参考，参考失踪，失踪参考，
 REF失踪，失踪参考，参考失踪，失踪参考，
参考失踪，失踪参考，参考失踪）; 
试
 {
的for（int i = 1; I< = m_word.ActiveDocument.InlineShapes.Count;我++）
 {
 m_i = I; 
 // CopyFromClipboardShape（）; 
线程线程=新主题（CopyFromClipbordInlineShape）; 
 thread.SetApartmentState（ApartmentState.STA）; 
 thread.Start（）; 
的Thread.join（）; 
} 
} 
终于
 {
对象保存= FALSE; 
 m_word.Quit（编号保存，裁判失踪，失踪参考）; 
 m_word = NULL; 
} 
} 
保护无效CopyFromClipbordInlineShape（）
 {
 InlineShape inlineShape = m_word.ActiveDocument.InlineShapes [m_i] 
 inlineShape.Select（）; 
 m_word.Selection.Copy（）; 
电脑电脑=新计算机（）; 
 //图片IMG = computer.Clipboard.GetImage（）; 
如果（！computer.Clipboard.GetDataObject（）= NULL）
 {
 System.Windows.Forms.IDataObject数据= computer.Clipboard.GetDataObject（）; 
如果（data.GetDataPresent（System.Windows.Forms.DataFormats.Bitmap））
 {
图像的图像=（图）data.GetData（System.Windows.Forms.DataFormats.Bitmap，真正）; 
 image.Save（使用Server.Mappath（〜/ ImagesGet / Image.gif的），System.Drawing.Imaging.ImageFormat.Gif）; 
 image.Save（使用Server.Mappath（〜/ ImagesGet / image.jpg文件），System.Drawing.Imaging.ImageFormat.Jpeg）; 
 
} 
，否则
 {
 LabelMessage.Text =数据在剪贴板并不像图片格式; 
} 
} 
，否则
 {
 LabelMessage.Text =剪贴板是空的; 
} 
} 
  

代码从的如何从文件Exctract图像（字）在C＃中的文件吗？

从Word文档图像转换为位图

I'm processing Microsoft Word files which contain math equations and images. I need to get these InlineShapes objects and store them as is & then restore them when needed.

I know how to get InlineShape objects from file, the problem is how can I store them. Saving them as images is not an option!
