Based on an excessively lengthy comment thread above, you claim to have this server-side code:

public JsonResult StudentInfo(List<object> StudentData)
    return Json(StudentData);

So, you're returning a List<object> to your client-side code. Then in your client-side code you try to access a property on an element in that list:

success: function (response) {

Well, to put is simply, object doesn't contain a property called Name. It never has, and it probably never will. So you can't access a property that doesn't exist. Hence, it's undefined in JavaScript.

It looks like you meant to define a class for your objects. Something as simple as this:

public class Student
    public string Name { get; set; }
    public int Age { get; set; }

Then you can use that class in your action method:

public JsonResult StudentInfo(List<Student> StudentData)
    return Json(StudentData);

Since Student does have a property called Name, you can use that property in your client-side code.
