目的，把远程服务器传回的html，解析到类里面，为gridview等提供数据源
1 、向远程服务器post数据
public int postdata(string url, string data, out string info)
        {

            info = "";
            cookiecontainer cc = new cookiecontainer();
            httpwebrequest request = webrequest.create(url) as httpwebrequest;
            request.cookiecontainer = cc;
            request.method = "post";
            request.contenttype = "application/x-www-form-urlencoded";
            stream requeststream = request.getrequeststream();
            byte[] bytearray = encoding.utf8.getbytes(data);
            requeststream.write(bytearray, 0, bytearray.length);
            requeststream.close();
            httpwebresponse response = request.getresponse() as httpwebresponse;
            uri responseuri = response.responseuri;
            stream receivestream = response.getresponsestream();
            encoding encode = system.text.encoding.getencoding("utf-8");
            streamreader readstream = new streamreader(receivestream, encode);
            string result = readstream.readtoend();
            info = result;
            return 0;

        }2、解析返回的html，有省略
 public classinfo[] getclass(string html)
        {

            arraylist ar = new arraylist();
            arraylist arr = new arraylist();
            string table = "";
            regex regtable = new regex(@"(?<=<table.*>).*?(?=</table>)", regexoptions.singleline);
            match ma = regtable.match(html);
            while (ma.success)
            {
                if (ma.value.trim() != "")
                {
                    arr.add(httputility.htmldecode(ma.value));
                }
                ma = ma.nextmatch();
            }
            for (int i = 0; i < arr.count; i++)
            {
                table = arr[i].tostring() + table;
            }

            regex reg = new regex(@"(?<=<.*?>).*?(?=<.*?>)", regexoptions.singleline);
            match m = reg.match(table);

            while (m.success)
            {
                if (m.value.trim() != "")
                {

                    ar.add(httputility.htmldecode(m.value));
                }
                m = m.nextmatch();
            }

           classinfo[] ci = new classinfo[classno];
            for (int i = 0; i < classno; i++)
            {
                ci[i] = new classinfo();
                ci[i].registerdate = (ar[i * 8 + 0]).tostring();

                ci[i].logindate = (ar[i * 8 + 1]).tostring();
                ci[i].logoutdate = (ar[i * 8 + 2]).tostring();
                ci[i].usemin = ar[i * 8 + 3].tostring();
                ci[i].classname = ar[i * 8 + 5].tostring();
                ci[i].classtype = ar[i * 8 + 6].tostring();
                ci[i].percent = ar[i * 8 + 7].tostring();

            }

 

            return ci;

        }
