无法在视图中看到视图模型属性

我仍然试图使用ViewModels和IEnumerable/List作为属性来思考。我显然错过了一些不允许我在我的观点中看到我的 IEnumerable 的东西。

我最终要做的是有一个视图，该视图将显示未分配到组的未分配用户列表（在本例中称为巡逻，PatrolId=0）。该表的每个成员旁边都有一个复选框。该表上方将是可用巡逻的下拉列表。管理员将来到页面以查看未分配的那些，从顶部的 DDL 中选择一个巡逻，检查他想要分配给该巡逻的用户，然后提交将从 DDL 传递 PatrolID 的表单并找到所有选定的成员，以便使用该 PatrolID 更新他们的记录。

在下面的视图中，当我遍历 Scout 属性时，我假设我能够在此部分中使用 Model.Scout，以便循环遍历并写出该 IEnumerable 中的所有成员。

@for (var i = 0; i < Model.Count(); i++)

但是，当我尝试在使用模型时使用智能感知来查看 Scout 属性时，我看不到该属性。除此之外，我认为在写出所有行之前，我需要首先检查 Scout 属性以查看是否有计数。同样，我看不到 Scout 属性以检查其计数。

视图模型

public class PatrolMemberViewModel
{
        [Key]
        public int MemberId { get; set; }
        public int PatrolId { get; set; }
        [Display(Name = "First Name")]
        public string FirstName { get; set; }
        [Display(Name = "Last Name")]
        public string LastName { get; set; }
        [Display(Name = "Phone")]
        public string PhonePrimary { get; set; }
        [Display(Name = "Email")]
        public string EmailPrimary { get; set; }
        public bool IsSelected { get; set; }
}
public class PatrolUnassignedViewModel
{
        public SelectList Patrols { get; set; }
        public IEnumerable<PatrolMemberViewModel> Scout { get; set; }
}

控制器

// GET: 
public ViewResult Unassigned()
{
    PatrolUnassignedViewModel unassinged = new PatrolUnassignedViewModel();
    unassinged.Patrols = new SelectList(repository.SelectAllPatrols());
    unassinged.Scout = repository.SelectAllUnassigned();
            
    return View(unassinged);
}
