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; }
}

我没有此类的视图模型，它只会用于在我的应用程序的其他视图模型中填充 SelectLists（通过存储库）。但是，我想创建一个像这样的属性，以连接 SelectLists/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，我收到一个错误，即 EmployeeName 列不存在。好的，有道理，因为这是我的模型，他们没有这样的专栏。

下面是一个使用 SelectList 的视图模型的简短示例：

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，我这样做：

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);

由于我没有 Employee 类的视图模型，我可以将这个 EmployeeName 属性放在哪里来替换 FirstName？如果有人能指出我正确的方向，我将不胜感激。

您不需要 EmployeeName 属性。在您的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);
