Getting employees list under manager

Question

I have two lists, one's for employees and the other is for department. I NEED TO print the employee list under manager. This is my code.

public class Model
{
    public static List<Employee> employees = new List<Employee>
    {

  new Employee { empID = "201", empName = "Afreen", DepartmentId = 201, designation = "Intern"},
                new Employee { empID = "202", empName = "Resmi", DepartmentId = 201, designation = "Software Developer" },
                new Employee { empID = "203", empName = "Najat", DepartmentId = 202, designation = "E- commerce representative" },
                new Employee { empID = "204", empName = "Bincy", DepartmentId = 203, designation = "buying team" },
                new Employee { empID = "205", empName = "Sara", DepartmentId = 204, designation = "Marketing associate" },
                new Employee { empID = "206", empName = "Kashif", DepartmentId = 201, designation = "Automative Testing" },
                new Employee { empID = "207", empName = "Noor", DepartmentId = 205, designation = "HR representative" },
                new Employee { empID = "208", empName = "Saad", DepartmentId = 201, designation = "Web developer" },
                new Employee { empID = "209", empName = "Kylie", DepartmentId = 205, designation = "HR representative" },
                new Employee { empID = "210", empName = "Kendall", DepartmentId = 203, designation = "buying team" }

};
        public static List<Department> departments = new List<Department>()
        {

             new Department {DepartmentId=201,  departmentname="IT", manager= "York" },
             new Department {DepartmentId=202,  departmentname="IT", manager= "York"   },
             new Department {DepartmentId=203,  departmentname="Buying", manager= "Mohammad"  },
             new Department {DepartmentId=204,  departmentname="Marketting", manager= "Chang"  },
             new Department {DepartmentId=205,  departmentname="HR", manager= "Ameera"},

             };
        }
    }
}
        public void deppp()
        {
            bool incorrect = true;
            Console.WriteLine("(get employees) Enter the manager's name?");
            var managename = Console.ReadLine();
            foreach (var deps in Model.departments)
            {
                foreach (var emps in Model.employees.Where(y => y.DepartmentId == deps.DepartmentId))
                {
                    while (incorrect)
                    {

                        if (string.IsNullOrEmpty(managename))
                        {
                            Console.WriteLine("Manager name cant be empty, enter name again");
                            managename = Console.ReadLine();
                        }
                        else if (!string.IsNullOrEmpty(managename) && !Model.departments.Any(x => x.manager.ToLower().Trim().Equals(managename.ToLower())))
                        {
                            Console.WriteLine("Manager name invalid, enter name again");
                            managename = Console.ReadLine();
                        }

                        //if (ManagerID == 0)
                        //{
                        //    Console.WriteLine("Manager ID cant be empty, enter name again");

                        //}

                        else
                        {
                            var ManagerID = Model.departments.Where(x => x.manager.ToLower().Equals(managename.ToLower())).Select(x => x.DepartmentId).FirstOrDefault();

                            var EmployeesUnderMan = Model.employees.Where(x => x.DepartmentId == ManagerID).Select(x => x.empName).ToList();

                            Console.WriteLine((string.Join(" ", EmployeesUnderMan)));

                            incorrect = false;
                        }
                    }
                }
            }
        }

Now how do i print a list of employees. where Managers are INCLUDED as employees,
