How do I pass the data from my View to the controller? – Asp.net

I have a concierge application where the user will register an entry and exit of vehicles, to register an entry I work with two tables, the user consults the associate by the license plate and checks if he is registered, yes I allow him to enter one of his another table, but I can’t find a way to pass this data to the controller and insert it into the database, that is, how do I get the data from my View? And how do I enter the data in the database? follows my code from the View that is displaying the form and the Controller…

public ActionResult Buscar(string texto)
    {
        VeiculosDB vb = new VeiculosDB();

        var placa = vb.VEICULOGERAL.Where(p => p.PLACA == texto);
        return View(placa);
    }

In a way in my plate variable I have the data that is being displayed, but how would I do an insert with this data ?

@model IEnumerable<Portaria.Models.VEICULOGERAL>

@{ 
ViewBag.title = "Chegada";
}

<div class="panel-body">
  @using (Html.BeginForm("Buscar", "Portarias", FormMethod.Get))
{
    <input type="text" class="form-control" name="texto" placeholder="Placa..." />
    <div class="form-group">
        <div class="">
            <input type="submit" value="Buscar" class="btn btn-default" name="texto" style="background-color:aliceblue" />
        </div>
    </div>
}

<table class="table">

    You are using submit form mechanism with GET method. This isn’t logical.

    GET === retrieve something from server

    POST/PUT === send something to server

    So regarding your case just change

     using (Html.BeginForm("Buscar", "Portarias", FormMethod.Get))

    to

     using (Html.BeginForm("Buscar", "Portarias", FormMethod.Post))

    Since you’re using this statement

    @model IEnumerable<Portaria.Models.VEICULOGERAL>

    your View will be populated based on the model’s values above.

    Split Buscar ActionResult to [HttpGet] and [HttpPost] methods.
    With [HttpGet] you will retrieve data with controller from data to view.
    with [HttpPost] action, you will retrieve data from view to database.

    Firstly define your db object globally(outside from action methods):

    VeiculosDB vb = new VeiculosDB();

    In your view make your Form method "post" like this:

    using (Html.BeginForm("Buscar", "Portarias", FormMethod.Post))

    inside the beginForm you can use a button with submit type like this:

    <button type="submit" class="btn btn-primary">Add</button>

    It will automatically send data to [HttpPost] action.

    Your [HttpPost] Action can be like this:

    [HttpPost]
    public ActionResult Buscar(Vehicle v)
            {
                vb.Carname.Add(v); //vb from your global db object that I mentioned above.
                vb.SaveChanges();
                return RedirectToAction("index");
            }
