I have the following code, but i`m having error of

Error 6 foreach statement cannot operate on variables of type 'int' because 'int' does not contain a public definition for 'GetEnumerator' C:\Dev\DEV\Code\MvcUI\Models\MappingModel.cs 100 13 MvcUI

How can I solve this?

Note: string [] projectID;

Class Employee { int id {get; set;} string Name {get;set;}

}

 public IEnumerable<SelectListItem> GetStudents()
    {
        List<SelectListItem> result = new List<SelectListItem>();
        foreach (var id in Convert.ToInt32(projectID))
        {
            foreach( Employee emp in Project.Load(id))
                result.Add(new SelectListItem
                {
                    Selected =  false,
                    Text = emp.ID.ToString(),
                    Value = emp.Name
                });

            return result.AsEnumerable();
        }


    }
