如何使用C#在Word文档中插入图片以及读取Word文档中的图片？

this.OpenFile(@"c:\1.doc",false);
        //读取并将图片保存到指定目录中

            int i = 0;
            foreach (Word.InlineShape ish in MyDoc.InlineShapes)
            {
                if ((ish.Type == Word.WdInlineShapeType.wdInlineShapeLinkedPicture) || (ish.Type==Word.WdInlineShapeType.wdInlineShapePicture))
                {
                    ish.Select();
                    MyWordApp.Selection.Copy();
                    Image image = Clipboard.GetImage();

                    Bitmap bitmap = new Bitmap(image);
                    bitmap.Save("c:\\pic" + i.ToString() + ".jpg");
                    i++;
                }
            }
