json格式如下： {"10000003":{"hall_id":"10000003","sys_point":"100000","xy_sys_point":"0"},"10000065":{"hall_id":"10000065","sys_point":"92162","xy_sys_point":"6275192","win_point":"5537000"}}我用的是JavaScriptSerializer js = new JavaScriptSerializer();方法，實(shí)體類已經(jīng)建過(guò)，實(shí)體類為嵌套，只是不知道json數(shù)據(jù)的10000003 和10000065  該如何讀取和寫(xiě)實(shí)體？請(qǐng)大家?guī)蛶兔?，謝謝了！
