c# word轉html（另存為)

方案一：

 /// <summary>
        /// word另存為html
        /// </summary>
        /// <param name="filePath"></param>
        private void WordToHTML(string filePath)
        {
            var rootPath = AppDomain.CurrentDomain.BaseDirectory;
            var fileName = Path.GetFileNameWithoutExtension(filePath);
            
 
object nothing = Missing.Value;
            object newPath = string.Format(@"{0}File\html\{1}.html", rootPath, fileName);
            object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatFilteredHTML;
            Microsoft.Office.Interop.Word.Application application = new Microsoft.Office.Interop.Word.ApplicationClass();
            Microsoft.Office.Interop.Word.Document document 
 
= application.Documents.Add(filePath, nothing, nothing);
            document.SaveAs2(newPath, format, nothing, nothing, nothing, nothing, nothing, nothing,
                nothing, nothing, nothing, Encoding.UTF8.CodePage, nothing, nothing, nothing);
            document.Close(nothing, nothing, nothing);
            application.Quit(nothing, nothing, nothing);
        }
