I have a C# list of students. I cannot remove Item based on Id.

Program.cs

        static void RemoveStudent(StudentManager studentManager)
        {
            Console.WriteLine("Which student? Insert ID:");
            int id = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine(id);
            studentManager.RemoveStudent(1);
        }

How student class looks like:

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

How StudentManagerClass looks like:

public class StudentManager
{
    private List<Student> students = new List<Student>();

    public void RemoveStudent(int id)
    {
        students.RemoveAt(id);
    }

Program exits without any prompt when trying to remove the element.
