Use jquery to asynchronously pass model-to-controller methods with complex attributes and set properties

The student class has a collection attribute courses, how to pass student together with the Set attribute courses to the Controller method?

public class Student
{
public string Studentname {get; set;}
Public ilist<course> Courses {get; set;}
}

public class Course
{
public string Coursename {get; set;}
}

-Ideas

In the front end of the assembly into a match with student, the corresponding object, and then use the json.stringify () or $.tojson () method to convert to the JSON format to pass to the Controller method, using the $.tojson () method needs to reference a jquery extension JS file.
