extract image from word file

Question

I have been trying the following C# code to extract image from the doc file but it is not working:

object missing = System.Reflection.Missing.Value;                  


        

Answer 1

Another option if it's a .docx file:

1. Rename the file to a .zip
2. Extract the contents
3. Look for the following directory in the extracted folder word/media

Yeah, it's not the C# way to do it as posted, but even writing the code to perform the 3 steps above would be a way of automating the process if that's what you are looking for.

I had the same problem I used spire library and i got the solution i am giving the link of that library use just add that dll files in your visual studio and copy the below code :

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++;
                        }
                    }
                }
            }}

Here's a local/non-web-page version.

Most of this code is copied from: http://www.csharphelp.com/2007/05/save-picture-from-clipboard-to-file-using-c/ - plus a few lines from Ekk's answer.

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");
}
