IEnumerable的DropDownList <string> 模型

Question

I have a IEnumerable list model containing different city names, I would like to make a DropDownList from this model, I saw an example that work, but for creating links, I think we can do the same thing for a Dropdownlist by looping through the list. How could I do that ?

@model IEnumerable<string>





    @foreach (var link in Model)
    {
      // ????
    }

Answer 1

使用已经为您提供的htmlhelper

@Html.DropDownList("cities", new SelectList(Model))

Answer 2

If you don't want to use HtmlHelpers, which, from your question, it sounds like you don't, you can use the following iterative method for an IEnumerable<string> :

<select name="myFormInputName">
@foreach (var link in Model)
{
  <option value="@(link)">@(link)</option>
}
</select>

Answer 3

The very simple, and basic form (without moving the SelectList to the controller) is :

@model IEnumerable<string>
@{
var selectList = new SelectList(Model) ;

}

@Html.DropDownList("MyDropDownListName", selectList)

Although I would prefer creating an extension to the HtmlHelper class, or using a "strong named" dropdownlist @Html.DropDownListFor(myvar=>myvar.City, selectList)
