How to correctly display radiobutton in asp.net mvc 5

I want to know what is the best way to display check boxes in asp.net mvc 5 application.

Attempt 1:

    @Html.RadioButton("SearchBy", "Name", true) <text> Name </text>
    @Html.RadioButton("SearchBy", "Location") <text> Location</text>


    [HttpPost]
    public ActionResult Create(CoverLetterViewModel viewModel, string searchBy)
    {//somecode}

Attempt 2:

     //prop
       public string SelectedRoleType { get; set; }
     //view
       <label>
            @Html.RadioButtonFor(m => m.SelectedRoleType, "JobSeeker", new { @class = "js-radio", id = "" })
            <span>Job Seeker</span>
        </label>

        <label>
            @Html.RadioButtonFor(m => m.SelectedRoleType, "Referrer", new { @class = "js-radio", id = "" })
            <span>Referrer</span>
        </label>
      //controller action
        [HttpPost]
        public ActionResult Create(CoverLetterViewModel viewModel)
        {//somecode}

Attempt 3: Now suppose I have 10 radiobutton, is there any efficient way to create radiobutton. I mean suppose I have a list of radiobuttonitem, Something like below

public List<SOME RADIBUTTON ITEM> radiobuttonlist {get;set;}

Question:

Can we somehow display radiobuttonsame way we handle List of Dropdown Item . Can we somehow avoid hardcoding "Referrer" AND "JobSeeker" text in view file.
