How to popular a class with a C#string list

Question

On the system I’m developing I send a select with multiple options to a list of string type in my controller, I now need to link this list I get from the view to the list with the login class I have in my model. The goal is that each position of the string list becomes a position in the new list.

For example I get the following list of values that were sent from the view select:

[0] = "147"

[1] = "56"

I need to link this array to my other login list, something like this

Login[0] = "147

Login[1] = "56"

I’ll put my codes with comments to explain better:

View:

<select class="selectpicker" multiple data-live-search="true" asp-for="ListaResponsaveis">
   <option value="147">João</option>
   <option value="212">Maria</option>
   <option value="33">Luiza</option>
</select>

Model:

//Aqui recebo as opções marcadas no select
public List<string> ListaResponsaveis { get; set; }

//Quero passar a lista que recebi da view para essa lista
public List<Responsaveis> ListaResponsaveisData { get; set; }
    
public class Responsaveis
{
   public string Login { get; set; }
}

Controller:

public async Task<IActionResult> CadastrarTarefa([FromForm] WebdeskTarefas webdeskTarefas)
{
//Criei essa variavel para receber os dados da outra lista
var ListaResponsaveis = webdeskTarefas.ListaResponsaveisData;

//Aqui tentei vincular cada possição do array da lista da view a minha lista, porém ele não mostra valor no webdeskTarefas.ListaResponsaveis[i]
for (int i = 0; i < webdeskTarefas.ListaResponsaveis.Count; i++)
{
   ListaResponsaveis[i].Login = webdeskTarefas.ListaResponsaveis[i];
}

Responsible listings is not a list already populated by select and belongs to the webdeskTarefas class?

The idea was not popular webdeskTarefas.ListaResponsaveisData?

If that’s what your code really is, it doesn’t make much sense. If I understood what you wanted to do, I would do it that way:

//Considerando que o parâmetro **webDeskTarefas** tenha como atributo a lista **ListaResponsaveis** e que esteja populada com os valores do select
public async Task<IActionResult> CadastrarTarefa([FromForm] 
WebdeskTarefas webdeskTarefas)
{
    for (int i = 0; i < webdeskTarefas.ListaResponsaveis.Count; i++) //com a lista webdeskTarefas.ListaResponsaveis ja populada pelo select
    {
       Responsaveis responsavel = new Responsaveis()
       {
           login = webdeskTarefas.ListaResponsaveis[i]
       };
       webdeskTarefas.ListaResponsaveisData.Add(responsavel);
    }
}
