asp.net how to convert Word files to HTML _ practical tips

#region file format conversion//Please refer to Microsoft.Office.Interop.Word applicationclass Word = new ApplicationClass (); Type Wordtype = Word.
GetType (); Documents docs = Word.

 Documents; Open file Type docstype = Docs.
 GetType (); 
 Object fileName = Wordpath;
 "F:\\cc.doc"; Document doc = (document) Docstype.invokemember ("Open", BindingFlags.InvokeMethod, NULL, (object) Docs, new object[] {

 FileName, True, true}); Determine if the file that is associated with the file conversion exists, or if it exists, delete it.

Files")) {Direct Ory.
 Delete (Htmlpath.replace (". html", ". Files"), true);

 }; Transform the format to invoke Word Save As method Type DocType =doc.

 Object savefilename = Htmlpath; //"F:\\aaa.html "; Doctype.invokemember ("SaveAs", BindingFlags.InvokeMethod, NULL, doc, new object[] {savefilename,
 wdsaveformat.wdformathtml});
 Quit Word wordtype.invokemember ("Quit", BindingFlags.InvokeMethod, NULL, Word, NULL);
