Eviar view parameter for action

Question

I have a views that lists my users, is basically in the pattern generated by Asp.net mvc with Entity, the data is in a table, and within this table I have a :

@Html.ActionLink("Aprovar cadastro", "Aprovar")

And I have inside the controller Action:

 [HttpGet]
    public ActionResult Aprovar(int? Id)
    {
        if(Id == null){return new HttpStatusCodeResult(HttpStatusCode.BadRequest);}
        else { 
               //A função será implementada aqui
        }
    }

Basically I need to pass the Id of a specific user to this controller, but I’m not succeeding.

Follow my view:

@model IEnumerable<ApegaPet.Models.ApplicationUser>
@{     Layout = "~/Views/Shared/_SideNavbar.cshtml";  }
@{
    ViewBag.Title = "Avaliar_Ong";
}


<h2>Avaliar requisição de cadastro de Ongs</h2>
<table class="table">
    <tr>
        <th>
            @Html.DisplayNameFor(model => model.nomerazao)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.endereco)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.telefone)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Name)
        </th>
        <th>
            @Html.DisplayNameFor(model => model.Email)
        </th>
    </tr>
    @foreach (var item in Model)
    {
        <tr>
            <td>
                @Html.DisplayFor(modelItem => item.nomerazao)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.endereco)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.telefone)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Name)
            </td>
            <td>
                @Html.DisplayFor(modelItem => item.Email)
            </td>
            <td>
                @Html.ActionLink("Aprovar cadastro", "Aprovar")
            </td>
        </tr>

    }

Must pass the third equal role is in your documentation:

@Html.ActionLink("Aprovar cadastro", "Aprovar", new {Id = item.id})

this is called method overload (overload)

Overload List:

• ^{Actionlink(Htmlhelper, String, String)}
• ^{Actionlink(Htmlhelper, String, String, Object)}
• ^{Actionlink(Htmlhelper, String, String, Object, Object)}
• ^{Actionlink(Htmlhelper, String, String, Routevaluedictionary)}
• ^{Actionlink(Htmlhelper, String, String, Routevaluedictionary, Idictionary)}
• ^{Actionlink(Htmlhelper, String, String, String)}
• ^{Actionlink(Htmlhelper, String, String, String, Object, Object)}
• ^{Actionlink(Htmlhelper, String, String, String, Routevaluedictionary, Idictionary)}
• ^{Actionlink(Htmlhelper, String, String, String, String, String, Object, Object)}
• ^{Actionlink(Htmlhelper, String, String, String, String, String, Routevaluedictionary, Idictionary)}

^{Reference: Overload List}

_{One observing its code in the controller is that this data may or may not be passed (int?), that is, it is not obligatory may need to find out what is the best option in this particular case.}
