How do you retrieve a URL value in MVC?

I am having a slight little problem and wondering is there anyway that you could help me?

I am passing information using angularJs to an MVC controller. I am passing an Id of a user to the controller to allow the admin to change the user into an administrator. Here is the code for the view,

<tr ng-repeat="r in students | filter : searchStudent">
    <td><input type="text" name="Id" value="{{r.ID}}" readonly id="AdminIdText" /></td>
    <td>{{r.username}}</td>
    <td>{{r.Email}}</td>
    <td>{{r.AccountStatus}}</td>
    <td><a href="{{r.ID}}">test</a></td>
    <td><input type="submit" value="Make Admin" class="btn btn-warning" /></td>
</tr>

Here is the controller,

 public ActionResult AdminStatus(int id)
    {
        int Id = id;
        //Connection to the database
        var db = WebMatrix.Data.Database.Open("Database");
            db.Execute("UPDATE tblaccount SET AccountStatus= 1 WHERE ID =" + id);


        db.Close();
        return View("AddAdministrator");
    }
}

What I am wondering is, how do you retrieve the numeric value that has been passed through to the controller? This is because placing the information into a model is not working correctly.

Thanks in advance

Use the MVC 'UrlHelper' to generate URLs that keep working even after controllers have been moved around:

@Url.Action("<ActionName>", "<ControllerName>", new { Area = "<AreaName>", parameter1 = parameter1Value, parameter2 = parameter2Value })

For example:

 @Url.Action("AdminStatus", "Admin", new { Area = "Admin", id = r.ID})

will hit the "AdminStatus" action in the "AdminController" in the Area named "Admin" and send a parameter named "id".

I think you need to do 2 things. Make the <a> tag look something like this:

<a href="Action/{{r.ID}}">

And add a controller method like this:

public ActionResult Action(int id)
{
    // Do something with the id
}

As long as the default route maps are set up in the MVC project, that should map the id value to the id parameter.

you can also use name attribute to get the id value to your controller method.

public void action(int Id)
{
   // your code
}
