使用C#调用Word的接口生成doc文件与htnl文件

　　　　 public static void WordTest()
        {
            Application app = new Application { Visible = true };
            app.Documents.Add();
            Document doc = app.ActiveDocument;
            Paragraph par = doc.Paragraphs.Add();
            par.Range.Text = "hehe C# hellop";

            string filename = AppDomain.CurrentDomain.BaseDirectory;
            doc.SaveAs2(FileName: Path.Combine(filename,"demo.html"), FileFormat: WdSaveFormat.wdFormatFilteredHTML);
　　　　　　　doc.SaveAs2(FileName: Path.Combine(filename, "demo.doc"), FileFormat: WdSaveFormat.wdFormatDocument97);
            doc.Close();
            app.Application.Quit();
        }
