how can try catch or something?

you should add try/catch handle errors.

    ftpwebrequest req = (ftpwebrequest)webrequest.create(@"ftp://" + **struploadip** + @"/" + struser);     req.method = webrequestmethods.ftp.makedirectory;     req.credentials = new networkcredential(struusername, strupassword);     try {         using (var resp = (ftpwebresponse)req.getresponse()) {             console.writeline(resp.statuscode);         }     } catch {         // todo: handle exception     }
