我一直在尝试使用以下C#代码从doc文件中提取图像,但它无法正常工作:

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");
                    }



                }

任何人都可以提供正确的代码来从word文件中提取图像吗?

另一个选项,如果它是.docx文件:

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

    是的,它不是C#的方式来发布它,但即使编写代码来执行上述3个步骤将是一种自动化过程的方式,如果这是你正在寻找的

if (Clipboard.GetDataObject() != null)
{
    IDataObject data = Clipboard.GetDataObject();

我遇到了与我使用spire库相同的问题,并且得到了解决方案,我正在提供该库的链接,只需在您的visual studio中添加该dll文件并复制以下代码即可:

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++;
                        }
                    }
                }
            }}
