I asked a question with another user but I do not know what happened that I could not recover the information and I had to create another one now. Anyway, I wanted to create a search field and I was given as response to controller and view below:

public class HomeController : Controller
{
    private readonly ModelDb db;
    public HomeController()
    {
       db = new ModelDb();
    }

   ~HomeController()
    {
      db.Dispose();
    }

    [HttpGet]
    public ActionResult Pesquisa()
    {
       return View();
    } 
    [HttpPost]
    public ActionResult Pesquisa(string texto)
    {
        return View(db.Pessoas.Where(x => x.Nome.Contains(texto)).OrderBy(x => x.Nome));
    }
}

View

@model IEnumerable<WebApp.Models.Pessoas>
@{ Layout = null; }
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Pesquisa</title>
</head>
<body>
<div>
@using (Html.BeginForm())
     {
         <p>Digite o nome</p>
         <input type="text" name="texto" id="texto" placeholder="Digite a pesquisa" />
         <div><button type="submit">Filtrar</button></div>   
     }
</div>
<table>
    <tr>
        <td>Id</td>
        <td>Nome</td>
    </tr>
@{
        if (Model != null)
        {
            foreach (var item in Model)
            {
                <tr>
                    <td>@item.PessoaId</td>
                    <td>@item.Nome</td>
                </tr>
            }
        }
    }
</table>
</body>
</html>

Great, that’s exactly what I needed, Harry Polter! Only now, I need to do the same thing but in the view I have to return information from two different tables. What’s the syntax for a controller Join or how do I call it in the view since I can’t put two models as:

@model IEnumerable<WebApp.Models.Pessoas>
@model IEnumerable<WebApp.Models.Informacoes>

?

The models

namespace Competências.Models
{
public class Informacoes
{
    public int Id { get; set; }

    [Required(ErrorMessage = "A Chapa é obrigatória.")]
    [StringLength(16, ErrorMessage = "A Chapa pode ter no máximo 16 caracteres.")]
    public string Chapa { get; set; }

    [Required(ErrorMessage = "O Nome é obrigatório.")]
    [StringLength(120, ErrorMessage = "O Nome pode ter no máximo 120 caracteres.")]
    public string Nome { get; set; }
}

public class Pessoas
{
    public int Id { get; set; }


    [Required(ErrorMessage = "É obrigatório descrever as atividades desempenhadas na empresa")]
    [StringLength(255, ErrorMessage = "O campo atividades pode ter no máximo 255 caracteres")]
    public string Atividades { get; set; }


    public int InformacoesId { get; set; }
    public virtual Informacoes Informacoes { get; set; }

}

Pass your template on the question please and it was I who answered the previous

You cannot pass two models in the same view, you must use Viewbag or Viewdata !!!

That! That’s right! Thank you so much for your help! That’s just what I needed! Only that I need at the time of return along with the text field, return the information Plate and Name of another table on the grid! How do I do this?

To pass on information from Controller for View use Viewbag or Viewdata.

Example:

Realize that Viewbag.Flow will be the transport to your View, can be used normally for various types of data.

public ActionResult Pesquisa(string texto)
{
        ViewBag.Fluxo = db.Fluxo.AsEnumerable();
        return View(db.Pessoas.Where(x => x.Nome.Contains(texto)).OrderBy(x => x.Nome));
}

View:

@model IEnumerable<WebApp.Models.Pessoas>
@{ Layout = null; }
@{    
    IEnumerable<WebApp.Models.Fluxo> modelFluxo = (IEnumerable<WebApp.Models.Fluxo>)ViewBag.Fluxo;
}

Another way would be with a Model class

Example:

public class Models
{
    public IList Model { get; set; }
    public Models()
    {
        Model = new List<Object>();
    }
    public void Add(Object model)
    {
        this.Model.Add(model);
    }
}

Controller

public ActionResult Pesquisa(string texto)
{
    Models.Models model = new Models.Models();
    model.Add(db.Fluxo);
    model.Add(db.Pessoas.Where(x => x.Nome.Contains(texto)).OrderBy(x => x.Nome));
    return View(model);
}

View:

@model WebApp.Models.Models
@{ Layout = null; }
@{  
    IEnumerable<WebApp.Models.Fluxo> modelFluxo = null;
    IEnumerable<WebApp.Models.Pessoas> modelPessoa = null;
    if (Model != null) { 
        modelFluxo = Model.Model[0] as IEnumerable<WebApp.Models.Fluxo>;
        modelPessoa = Model.Model[1] as IEnumerable<WebApp.Models.Pessoas>;
    }
}
