Asp.net mvc 在viewmodels中填充SelectList

我有一个由以下模型表示的旧表：

public class Employee
{
    [Key]
    [Column("employee_id")]
    public string EmployeeId { get; set; }

    [Column("first_name")]
    public string FirstName { get; set; }

    [Column("last_name")]
    public string LastName { get; set; }

    [Column("active")]
    public bool Active { get; set; }
}

我没有此类的viewmodel，它将仅用于填充我应用程序中其他viewmodel中的SelectList（通过存储库）。但是，我想创建一个类似这样的属性，以连接SelectList/下拉列表的名字和姓氏：

    private string _EmployeeName;
    public string EmployeeName
    {
        get
        {
            return _EmployeeName;
        }
        set
        {
            _EmployeeName = this.FirstName + " " + this.LastName;
        }
    }

当我将EmployeeName放入我的Employee模型时，我得到一个错误，即列EmployeeName不存在。好的，这很有意义，因为这是我的模型，他们的专栏没有这样的内容

下面是一个使用SelectList的ViewModel的简化示例：

public class EquipmentViewModel
{
    [Display(Name = "Equipment ID:")]
    public string EquipmentId { get; set; }

    [Required(ErrorMessage = "Equipment name is required.")]
    [Display(Name = "Equipment Name:")]
    [MaxLength(128)]
    public string EquipmentName { get; set; }

    public SelectList EmployeeList { get; set; }
}

在我的控制器中，我执行以下操作：

var emp = iEmployeeRepository.FindBy(x => x.Active == true).OrderBy(x => x.FirstName);
var equipmentViewModel = new EquipmentViewModel
{
    EquipmentId = e.EquipmentId,
    EquipmentName = e.EquipmentName,
    OriginatorEmployeeId = e.OriginatorEmployeeId,
    EmployeeList = new SelectList(emp, "EmployeeId", "FirstName"),
};
return View(equipmentViewModel);

由于Employee类没有viewmodel，我可以将此EmployeeName属性放在哪里来替换FirstName？如果有人能给我指出正确的方向，我将不胜感激。

你不需要员工姓名财产。在控制器中执行此操作：

var emp = iEmployeeRepository.FindBy(x => x.Active == true)
                             .OrderBy(x => x.FirstName)
                             .Select(x => new { EmployeeId = x.EmployeeId, EmployeeName = x.FristName + " " + x.LastName });
var equipmentViewModel = new EquipmentViewModel
{
    EquipmentId = e.EquipmentId,
    EquipmentName = e.EquipmentName,
    OriginatorEmployeeId = e.OriginatorEmployeeId,
    EmployeeList = new SelectList(emp, "EmployeeId", "EmployeeName"),
};
return View(equipmentViewModel);

好极了！我从没想过。我想我把事情弄得太复杂了。谢谢
