How to user String to Get Data?

it means that maybe i can get data like this in apex(just like DataTable in some other language such as c#,):

 

<sObject sOs=[select name,id from account limit 1] ;

 

//use the filedname to get data 

String fieldname="name"; 

String fieldvalue; 

 

fieldvalue = sOs.get(fieldname);  Maybe sOs[fieldname];   Maybe sOs.getValue(fieldname);

 

How to do it as my case in apex?
