parsing - c# error when parse string to JSON -

i have bit text when trying parse json in c# program through error "error reading jobject jsonreader. current jsonreader item not object: string. path '', line 1, position 6."

text:

"data":[{"username":"sex","bio":"#u24e2kyu24d4u24e7pressionsninstagramsex@gmail.com","website":"","profile_picture":"http://images.ak.com/profiles/profile_37086_75sq_1363954517.jpg","full_name":"sex","id":"37086"}] 

my code:

jobject obj = jobject.parse(text); 

i want username value when parse json

i put { } around entire string.

i.e. change text to:

{"data":[{"username":"sex","bio":"#u24e2kyu24d4u24e7pressionsninstagramsex@gmail.com","website":"","profile_picture":"http://images.ak.com/profiles/profile_37086_75sq_1363954517.jpg","full_name":"sex","id":"37086"}]}
