c# - ASP.NET Razor 页面下拉列表

Question

 <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>

所以我的网站上有以下代码。我想要做的是，而不是有一个文本字段，您可以在其中键入县名，我希望拥有县名下拉列表，用户可以在其中按名称选择它，并且它仍将注册为数字。 (例如，他不会写“1”，而是单击并从我制作的列表中选择 County1)

编辑:
好的，现在我有这个代码

@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" } })

我如何编写它来替换 @Html.EditorFor(model => model.CountyId 与 DropDownList 选择？

Edit2:我如何使用 @Html.DropDownListFor ？

                @Html.ValidationMessageFor(model => model.CountyId, "", new { @class = "text-danger" })
            </div>
        </div>
