Loop through JSON object ?

[websam]

Hello,

I'm making a class to create a table and fill that table with data
from JSON. But I can't find a way to loop throug my JSON object
without hardcoding the key/value pair.

My JSON looks like this :

{"d":[
    {"Id":1,"RoleName":"Master","AddDate":"10-08-2008
21:28:23","Active":false},
    {"Id":2,"RoleName":"Administrator","AddDate":"10-08-2008
23:46:13","Active":true},
    {"Id":3,"RoleName":"SuperUser","AddDate":"11-08-2008
09:41:49","Active":true},
    {"Id":4,"RoleName":"User","AddDate":"10-08-2008
23:16:44","Active":true}
]}

How can I loop through this without knowing the key's Id, RoleName,
ect. ?
