从word文件中提取图像

Question

我一直在尝试以下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");
                    }



                }

任何人都可以提供从word文件中提取图像的正确代码吗？

            }
            else
            {
                LabelMessage.Text="The Data In Clipboard is not as image format";
            }
        }
        else
        {
            LabelMessage.Text="The Clipboard was empty";
        }
    }

从代码复制如何从文档(word文件)的文件在C#中Exctract图像？

Answer 2

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. 在解压出来的文件夹word/media中查找以下目录

是的，这不是 C# 发布的方式，但即使编写代码来执行上述 3 个步骤，如果这就是您正在寻找的，那也是一种自动化过程的方式。
