MVC 4 中的 DropDownList 与 Razor [英] DropDownList in MVC 4 with Razor

问题描述

我正在尝试在剃刀视图上创建一个 DropDownList.

I'm trying to create a DropDownList on a razor view.

有人能帮我解决这个问题吗?

Would someone help me with this?

普通 HTML5 代码:

<select id="dropdowntipo">
    <option value="Exemplo1">Exemplo1</option>
    <option value="Exemplo2">Exemplo2</option>
    <option value="Exemplo3">Exemplo3</option>
</select>

我试过了:

@{
    var listItems = new List<ListItem> { 
        new ListItem { Text = "Exemplo1", Value = "Exemplo1" }, 
        new ListItem { Text = "Exemplo2", Value = "Exemplo2" }, 
        new ListItem { Text = "Exemplo3", Value = "Exemplo3" } 
    };
}

@Html.DropDownListFor(model => 
    model.tipo, 
    new SelectList(listItems), 
    "-- Select Status --"
)

推荐答案

@{
   List<SelectListItem> listItems= new List<SelectListItem>();
   listItems.Add(new SelectListItem
        {
          Text = "Exemplo1",
          Value = "Exemplo1"
        });
   listItems.Add(new SelectListItem
        {
            Text = "Exemplo2",
            Value = "Exemplo2",
            Selected = true
        });
   listItems.Add(new SelectListItem
        {
            Text = "Exemplo3",
            Value = "Exemplo3"
        });
}

@Html.DropDownListFor(model => model.tipo, listItems, "-- Select Status --")
