Facing issues on converting list to datatable c#

I have below code and facing issues on converting list to datatable. This line gives error. DataTable studentTable = Students;

public DataTable GetDetails()
        {

            List<Student> Students = new List<Student>(){
                new Student() { Name = "Jack", Age = 1, StudentId = 100 },
                new Student() { Name = "Smith", Age = 2, StudentId = 101 },   
                       new Student() { Name = "Smit", Age = 3, StudentId = 102 },};
            DataTable studentTable = Students;// This line gives error.
        }

        public class Student
        {
            public string Name;
            public int Age;
            public int StudentId;
        }

Please correct me.

Instead of making lists, you should make columns and then add rows.

Studenttable.columns.add("Name", typeof(string));
Studenttable.columns.add("Agg", typeof(int));
Studenttable.columns.add("StudentID", typeof(int));

Studenttable.Rows.add("Jack",1,100);
