The two images are how my array is. In the first image I have an array with 3 items, the first of the month of April and contains 4 passages. For each ticket I have the respective participants. My problem is in sending this array to my view , because I can not get some properties at runtime as passagem.participante .

I tried to break this down into three arrays , but when I run via foreach on the screen it does not display properly with the month and its participants with their passages.

How to make an array only that I could access all properties and play them on the screen?

Here's how the view looks today, but I need to sync the information as I said earlier.

@using WebProvider.BMW_Incentivo.Domain.Models
@model WebProvider.BMW_Incentivo.Admin.Models.GerenciaPassagemModel

@{
    ViewBag.Title = "Gerenciamento de Passagens";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

Turn these methods into your ViewModel on properties that are consuming the IEnumerable Period that was set by the Controller

For example (ViewModel class: MobilityModel )

private IEnumerable<Periodo> listaPeriodo_
public IEnumerable<Periodo> ListaPeriodo { 
   get { return this.listaPeriodo_; } 
   set { this.listaPeriodo_ = value; } //Seta pelo Controller
}

public IEnumerable<int> ListaAno {
   get { 
       foreach (Periodo p in listaPeriodo_)
       {
           yield p.Ano;
       }
   }
}

public IEnumerable<Passagem> ListaParticipante {
   get { 
       foreach (Periodo p in listaPeriodo_)
       {
           for each (Passagem ps in p.Passagem)
               yield ps;
       }
   }
}

In your view, you should use:

@foreach (Passagem participante in Model.ListaParticipante.Distinct())
@foreach (int ano in Model.ListaAno.Distinct().OrderBy(p => p))
@foreach (Periodo periodo in Model.ListaPeriodo)

It does not seem to be a View problem: it's just a feature of the Entity Framework, which does not load participants alone because it's a nesting level greater than 1, (level 1), but does not load aggregate pass data (level 2 or more).

I do not know how your code is in the Controller , but I would recommend using the .Include() method to force the aggregate data load. For example:

var gerenciaPassagens = context.GerenciaPassagensModels
    .Include(gp => gp.Passagem.Participante)
    .Where(/* Seus parâmetros para carga das informações */)

return View(gerenciaPassagens);
