I have this code that makes me a query an action of my controller, which returns a list in JSON

function CargPregRegist(valor) {
    $.ajax({
        type: 'POST',
        url: '@Url.Action("CargPregTipo")',
        data: "tipo=" + valor,
        contentType: "application/x-www-form-urlencoded",
        dataType: "json",
        success: function (data) {
            if (data) {

            }
        }
    });
}

What I have thought to do is capture the result of data but with c # so I can make a query with razor, someone knows how I can read that data with c # ????? I'm working with asp.net mvc 5

part of what I have planned to do is this

@foreach (var m in t)
                    {
                        if (Model.Sto_TipoAlertas_Preguntas.lol(m.CodigoInterno1).TipoAlerta1 > 0)
                        {
                            <option value='@m.CodigoInterno1' selected>@m.DetallePregunta1</option>
                        }
                        else
                        {
                            <option value='@m.CodigoInterno1'>@m.DetallePregunta1</option>
                        }
                    }

What this part of the code has to do, select the ones that do comply with and show in a separate list now where is the 0 is what I'm going to replace by the way I get the result of ajax

c# ajax asp.net asp.net-mvc-5

You add the code similar to this:

if (data){
  for(i in data) {
     $("#id_select").append("<option value=" + data[i].CodigoInterno1 +
       ">" + data[i].DetallePregunta1 + "</option>");
   }
}

in the view you create your select:

<select id="id_select">
   <option value="0">[--Seleccione un Nombre--]</option>
</select>

C # code where the answer is formatted:

var lstHtml= new StringBuilder();
                lstHtml.Append("<option selected='selected' value='-1'>-- Seleccionar --</option>");

                lstHtml.Append(string.Join(string.Empty, lista.Select(x =>
                string.Format("<option value='{0}'>{1}</option>",
                x.Id,
                x.Descripcion
                )).ToList()));
                comboHtml = lstHtml.ToString();

Ajax answer code:

if (data) {
       $("#id_select").html(data.comboHtml);
        }
