c# – 从word文件中提取图像

导读：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.Doc

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);

            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？
