Query in .NET Core

I'm learning the MVC logic applied in .NET Core but I have some doubts about doing CRUD process, more specifically Query .

• How can I make the click of the button communicate with a Controller and the same, request the information for the Model , it returns the result for Controller and the results are displayed on the screen?

Follow the code.

View.

@model WebApplication1.Models.CepViewModel
<h2>Manutenção de Cep</h2>
<div class="container" style="margin-top: 50px;">
<form asp-controller="Cep" asp-action="Cadastro" method="post">
    <div class="form-group">
        <label class="control-label">CEP</label>
        <input asp-for="CepCodigo" style="margin-left: 90px" width="50px" />
        <label style="margin-left: 90px" class="control-label">LOGRADOURO</label>
        <input asp-for="CepLogr" style="margin-left: 90px" width="50px" />
        <br />
        <label class="control-label">ENDEREÇO</label>
        <input asp-for="CepEnd" style="margin-left: 40px" width="50px" />
        <label style="margin-left: 90px" class="control-label">COMPLEMENTO</label>
        <input asp-for="CepCompl" style="margin-left: 82px" width="50px" />
        <br />
        <label class="control-label">BAIRRO</label>
        <input asp-for="CepBairro" style="margin-left: 64px" width="50px" />
        <label style="margin-left: 90px" class="control-label">CIDADE</label>
        <input asp-for="CepCidade" style="margin-left: 138px" width="50px" />
        <br />
        <label>UF</label>
        <input asp-for="CepUF" style="margin-left: 100px; width: 50px;" />
        <br />
        <br />
        <div class="form-group">
            <input type="submit" value="Consulta" />
        </div>
    </div>
    </div>
</form>

Controller.

   public class CepController : Controller
    {
        public IActionResult Cadastro()
        {
            return View();
        }
        public IActionResult Consulta()
        {
            return View();

        }
    }
}

Model.

    public class CepViewModel
    {
        public string CepCodigo { get; set; }
        public string CepLogr { get; set; }
        public string CepEnd { get; set; }
        public string CepCompl { get; set; }
        public string CepBairro { get; set; }
        public string CepCidade { get; set; }
        public string CepUF { get; set; }
        public int CepSetor { get; set; }
        public string CepRegiao { get; set; }
        public string CepRota { get; set; }


        public CepViewModel TakeCepById(int Id)
        {
            CepViewModel cep = null;

            using (var connection = new SqlConnection("DBConect"))
            {

                cep = connection.Query<CepViewModel>("Select * From CEP WHERE CepCodigo = @CepCodigo",
                        new { CepCodigo = Id }).SingleOrDefault();
                return cep;
            }

        }
    }
}
