从word文件中提取图像

Question

我一直在尝试使用以下 C# 代码从 doc 文件中提取图像，但它不起作用：

object missing = System.Reflection.Missing.Value;            
            Microsoft.Office.Interop.Word.Application oWord = new Microsoft.Office.Interop.Word.Application();
            Microsoft.Office.Interop.Word.Document oDoc = new Microsoft.Office.Interop.Word.Document();
            oWord.Visible = false;
            object str1 = "C:\\doc.doc";
            oDoc = oWord.Documents.Open(ref str1, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);

            if (oDoc.InlineShapes.Count > 0)            {


                for (int j = 0; j < oDoc.InlineShapes.Count; j++)
                {  

                    oWord.ActiveDocument.Select();
                    oDoc.ActiveWindow.Selection.CopyAsPicture();

                    IDataObject data = Clipboard.GetDataObject();                    

                    if (data.GetDataPresent(typeof(System.Drawing.Bitmap)))
                    {
                        object bm = data.GetData(DataFormats.Bitmap);

                        Bitmap bmp;
                        bmp = (Bitmap)data.GetData(typeof(System.Drawing.Bitmap));

                        bmp.Save("C:\\test.bmp");
                    }



                }

谁能给出从word文件中提取图像的正确代码？

我在使用 spire 库时遇到了同样的问题，我得到了解决方案，我提供了该库的链接，只需在您的 Visual Studio 中添加该 dll 文件并复制以下代码：

enter code here



        if (file.ShowDialog() == DialogResult.OK) //if there is a file choosen by the user  
        {
            object path = file.FileName; //get the path of the file  
            object readOnly = true;

            Spire.Doc.Document document = new Spire.Doc.Document(file.FileName);
            int index = 1;

            //Get Each Section of Document  
            foreach (Spire.Doc.Section section in document.Sections)
            {
                //Get Each Paragraph of Section  
                foreach (Spire.Doc.Documents.Paragraph paragraph in section.Paragraphs)
                {
                    StringBuilder sb = new StringBuilder();
                    sb.AppendLine(paragraph.Text);//storing the text of word in string builder
                    Console.WriteLine(sb);
                    //Get Each Document Object of Paragraph Items  
                    foreach (DocumentObject docObject in paragraph.ChildObjects)
                    {
                        //If Type of Document Object is Picture, Extract.  
                        if (docObject.DocumentObjectType == DocumentObjectType.Picture)
                        {
                            DocPicture pic = docObject as DocPicture;

                            String imgName = String.Format(@"E:\C#\OnlineExam\Question\{0}.png", index);

                            //Save Image  
                            pic.Image.Save(imgName, System.Drawing.Imaging.ImageFormat.Png);
                            index++;
                        }
                    }
                }
            }}

如果是.docx 文件，则另一种选择：

1. 将文件重命名为.zip
2. 提取内容
3. 在解压的word/media文件夹中查找以下目录

是的，这不是发布的 C# 方式，但即使编写代码来执行上述 3 个步骤，如果这正是您所寻找的，这也是一种自动化流程的方式。

这是一个本地/非网页版本。

大部分代码都复制自：http://www.csharphelp.com/2007/05/save-picture-from-clipboard-to-file-using-c/ - 加上 Ekk 的回答中的几行。

InlineShape inlineShape = m_word.ActiveDocument.InlineShapes[m_i];
inlineShape.Select();
m_word.Selection.Copy();
if (Clipboard.GetDataObject() != null)
{
    IDataObject data = Clipboard.GetDataObject();

    if (data.GetDataPresent(DataFormats.Bitmap))
    {
        Image image = (Image)data.GetData(DataFormats.Bitmap,true);

        image.Save("image.bmp",System.Drawing.Imaging.ImageFormat.Bmp);
        image.Save("image.jpg",System.Drawing.Imaging.ImageFormat.Jpeg);
        image.Save("image.gif",System.Drawing.Imaging.ImageFormat.Gif);
    }
    else
    {
        MessageBox.Show("The Data In Clipboard is not as image format");
    }
}
else
{
    MessageBox.Show("The Clipboard was empty");
}
