How to convert JSON Array to List<>?

This is my json and I need to access the values under each object in the attendance array:

{"name":" ","course":"","attendance":[{"name":"INTERNATIONAL FINANCE","type":"Theory","conducted":"55","present":"50"},{"name":"INDIAN CONSTITUTION","type":"Theory","conducted":"6","present":"6"}]}

Here is my code:

public class Att
{

    public class Attendance
    {
        public string name { get; set; }
        public string type { get; set; }
        public string conducted { get; set; }
        public string present { get; set; }
    }


    public Att(string json)
    {
        JObject jObject = JObject.Parse(json);
        JToken jUser = jObject;

        name = (string)jUser["name"];
        course = (string)jUser["course"];
        attender = jUser["attendance"].ToList<Attendance>;

    }

    public string name { get; set; }
    public string course { get; set; }
    public string email { get; set; }
    //public Array attend { get; set; }

    public List<Attendance> attender { get; set; }
}

It is the attender = jUser["attendance"].ToList<Attendance>; line that I have a problem with. It says,

Cannot convert method group ToList to non-delegate type. Did you intend to invoke this method?

How do I access those values?

You wanted to write:

attender = jUser["attendence"].ToList<Attendance>(); // notice the ()

About the Error: When you dont put the parantheses there, C# assumes you want to assign the function (delegate) ToList to the varaible attender, instead of invoking it and assign its return value.

You have a typo!

attendance vs attendence

And this should work

attender = jUser["attendance"].ToObject<List<Attendance>>();

You may find the running result at DotNetFiddle
