ASP.NET Razor page dropdown list

 <div class="form-group">
            @Html.LabelFor(model => model.CountyId, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.CountyId, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.CountyId, "", new { @class = "text-danger" })
            </div>
        </div>

So I have the following code on my website. What I want to do is instead of having a text field where you type the countyID I would like to have the county name dropdown list where the user selects it by name and it would still register as a number. (For example instead of writing "1" he would just click and choose County1 from a list I make)

Edit: Alright now I have this code

@Html.DropDownList("Counties", new List<SelectListItem>
                   {
                       new SelectListItem {Text = "Alba", Value = "1", Selected = true },
                       new SelectListItem {Text = "Arad", Value = "2" },
                       new SelectListItem {Text = "Arges", Value = "3" },
                       new SelectListItem {Text = "Bacau", Value = "4" },
                   }, "Select County")
                @Html.EditorFor(model => model.CountyId, new { htmlAttributes = new { @class = "form-control" } })

How do I write it to replace the @Html.EditorFor(model => model.CountyId with the DropDownList selection?

Edit2: how do I use @Html.DropDownListFor ?

There are so many ways to do this, you can use this :

<div class="form-group col-4">
                                <label for="issueinput6">category</label>
                                <select id="issueinput6" class="form-control" data-toggle="tooltip" data-trigger="hover" data-placement="top"
                                        data-title="Status">
                                    @foreach (var item in ViewData["Categoryes"] as IList<AirPortModel.Models.Category>)
                                    {

                                        <option value="@item.Id">@item.CategoryName</option>
                                    }

                                </select>
                            </div>

This way, you have all the information you want as a drop down. These codes are from my project but you can change the names to use it for your own. Also, you can use this pic of code to solve your problem.

<select data-val="true" data-val-required="The Category field is required." id="category" name="1">
<option value="">Pick one</option>
<option selected="selected" value="0">blabla</option>
<option value="1">blabla</option>
<option value="2">blabla</option>
<option value="3">blabla</option>
<option value="4">blabla</option>
<option value="5">blabla</option>
<option value="6">blabla</option>

You can use the Html.DropDownListFor helper method

Add a new property to your view model to store the dropdown options. This property should be of type List

public class CreateUser
{
  public int CountryId {set;get;}
  public List<SelectListItem> Countries {set;get;}
}

Now in your GET action, populate the Countries collection property value on this view model object.

public ActionResult Create()
{
  var vm = new CreateUser();
  vm.Countries = new List<SelectListItem> {
          new SelectListItem { Value="1", Text="USA" },
          new SelectListItem { Value="2", Text="Canada" },
          new SelectListItem { Value="3", Text="Mexico" }
        };
 return View(Vm);
}

And in your view

@model CreateUser
@using(Html.BeginForm())
{
  <label>Select country</label>
  @Html.DropDownListFor(s=>s.CountryId,Model.Countries,"Select one")
  <input type="submit" />      
}

            <div class="col-md-10">
               @Html.DropDownListFor(model => model.CountyId, new List<SelectListItem>
                       {
                           new SelectListItem {Text = "Alba", Value = "1", Selected = true },
                           new SelectListItem {Text = "Arad", Value = "2" },
                           new SelectListItem {Text = "Arges", Value = "3" },
                           new SelectListItem {Text = "Bacau", Value = "4" },
                       }, new { @class = "form-control" })
                @Html.ValidationMessageFor(model => model.CountyId, "", new { @class = "text-danger" })
            </div>
        </div>

Buda,

Probably you need to use the DropDownListFor html helper.
