如何将孩子的名字列出来？

Question

enter image description here我打算返回已经接种疫苗的孩子的名字。 发生的事情是它什么也没有返回给我，因为如果我调用ID，它将返回孩子的ID。

模型VacinacaoIndexData

      using GestCentros.Models;
using System.Collections.Generic;

namespace GestCentros.ViewModels
{
    public class VacinacaoIndexData
    {
       public IEnumerable<Vacinacao> Vacinacoes { get; set; }
        public IEnumerable<Vacina> Vacinas { get; set; }
        public IEnumerable<Enrollment> Enrollments { get; set; }

    }
}

控制器

public ActionResult Index(int? id, int? Idvacina)
    {
        var user = db.Users.Where(u => u.UserName == User.Identity.Name).FirstOrDefault();

        if (user == null)
        {
            return RedirectToAction("Index", "Home");
        }    
        var viewModel = new VacinacaoIndexData();    
        viewModel.Vacinacoes = db.Vacinacao
            .Include(v => v.Vacinas)
            .Include(v => v.Crianca)
            .Where(c => c.IdCentro == user.IdCentro);  

        if (id != null)
        {
            ViewBag.IdVacinacao = id.Value;
            viewModel.Vacinas = viewModel.Vacinacoes
                .Single(i => i.IdVacinacao == id.Value).Vacinas;
        }    
        if (Idvacina == null) return View(viewModel);           
            ViewBag.IdVacina = Idvacina.Value;
            // Lazy loading
            viewModel.Enrollments = viewModel.Vacinas.Single(x => x.IdVacina == Idvacina).Enrollments;
        // Explicit loading
        Vacina selectedVacina = viewModel.Vacinas.Single(x => x.IdVacina == Idvacina);    
        db.Entry(selectedVacina).Collection(x => x.Enrollments).Load();

            foreach (var enrollment in selectedVacina.Enrollments)
            {
                db.Entry(enrollment).Reference(x => x.Centro).Load();
            }    
            viewModel.Enrollments = selectedVacina.Enrollments;            

        return View(viewModel);
    }

在“字段名称”中，我想显示“子名称”，但不返回任何内容

      @model GestCentros.ViewModels.VacinacaoIndexData

@{
    ViewBag.Title = "Index";
}

<h2 class="text-center">Lista de Crianças Vacinadas</h2>

<table class="table">

        <th>Nome</th>
        <th>Data Vacinação</th>

    </tr>

    @foreach (var item in Model.Vacinacoes)
     {
        string selectedRow = "";
        if (item.IdVacinacao == ViewBag.IdVacinacao)
        {
            selectedRow = "success";
        }
        <tr class="@selectedRow">
