I m trying to implement lamda expression in my ASP.NET MVC project

IEnumerable<int> employeeIds = Employee.GetAllEmployees()
    .Select(emp => emp.EmployeeID);
foreach (int id in employeeIds)
{
    Console.WriteLine(id);
}

public static List<Employee> GetAllEmployees()
       {
          EmployeeDBContext db = new EmployeeDBContext();
           List<Employee> lstEmployees = new List<Employee>();

           lstEmployees = db.Employees.ToList();
           return lstEmployees;

       }

public ActionResult EmpOutput()
       {
           StudentDBContext db = new StudentDBContext();
           IEnumerable<int> employeeIds = db.Employees
           .Select(emp => emp.Id);
           return View(employeeIds);
       }

The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery`1[System.Int32]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[DemoWithMVC.Models.Employee]'.
