在asp.net mvc中为具有一对多关系的模型创建视图模型

public class DepartmentViewModel
{
    public Department Department { get; set; }
    public List<Employee> Employees { get; set; }
}

public ActionResult DepartmentDetails(int departmentId)
{
    Department department = db.Departments.Find(departmentId);
    List<Employee> employees = db.Employees.Where(e => e.DepartmentId == departmentId).ToList();

    DepartmentViewModel viewModel = new DepartmentViewModel
    {
        Department = department,
        Employees = employees
    };

    return View(viewModel);
}

@model DepartmentViewModel

<h2>@Model.Department.Name</h2>

<h3>Employees:</h3>
<ul>
    @foreach (var employee in Model.Employees)
    {
        <li>@employee.Name</li>
    }
</ul>
