listBox不将值发送回控制器

Question

我试图从给定的选项中选择几个选项，然后将选择的选项发送回控制器。

The view (image) is something like this:

我遇到的问题是这些值不会发送回控制器。我可以将项目从一个ListBox移动到另一个.... @Html.ListBoxFor(model => model.participantes, Model.participantes.Select(x => new SelectListItem { Text = x.nombre, Value = x.id.ToString() }), new { id = "listBoxSeleccionados", style = "width: 180px; height: 200px; resize: none;" }) .... @Html.ListBoxFor(model => model.posiblesparticipantes, Model.posiblesparticipantes.Select(x => new SelectListItem { Text = x.nombre, Value = x.id.ToString() }), new { id = "listBoxPosibles", style = "width: 180px; height: 200px; resize: none;" }) 。 代码如下：

查看

public ActionResult Create() 
{
    ....
    prueba.posiblesparticipantes = Pers.listaPersonaParticipantes();
    prueba.participantes = new List<ModeloPersona>();
    return View(prueba);
}

public ActionResult Create(createCurso_prueba model, FormCollection collection)
{
    try
    {
    }
    catch
    {
        return View();
    }
}

控制器

public class createCurso_prueba
{
    ....
    public List<ModeloPersona> posiblesparticipantes { get; set; }
    public List<ModeloPersona> participantes { get; set; }
    ....
}

模型

private int Judge(int Speed, int ViolationLimit, int SpeedLimit, int ExceedInstance) {
    if (Speed>=1 && Speed=<SpeedLimit) {
        ExceedInstance += 1;
    }
    return ExceedInstance;
}
