Asp.net mvc 获取MVC4中dropdownlist的值

我是MVC新手告诉我如何在controller中检索所选的dropdownlist值 这就是我向dropdownlist添加值的方式

List<SelectListItem> items = new List<SelectListItem>();
            items.Add(new SelectListItem { Text = "What is your Place of Birth?", Value = "What is your Place of Birth?" });
            items.Add(new SelectListItem { Text = "What is your favourite Book?", Value = "What is your favourite Book?" });
            items.Add(new SelectListItem { Text = "What is your childhood friend name?", Value = "What is your childhood friend name?" });
            items.Add(new SelectListItem { Text = "What is your first car make and model?", Value = "What is your first car make and model?" });
            items.Add(new SelectListItem { Text = "What is your favourite place?", Value = "What is your favourite place?" });
            ViewData["ddlitems"] = items;

在模型上，为值设置一个属性：

class ModelClass
{
    public string DropdownValue{get; set;}
}

然后使用以下Razor语法

@Html.DropdownListFor(m => m.DropdownValue, "ddItems");

---

这将创建一个名为“与模型属性相同”的下拉列表，它将自动使用模型发回。获取所选选项值的最简单方法就是将元素的ID与正在发布到

ActionResult

的ID相匹配。因此，如果您的

select

元素呈现为

<select id="SomeID">
    <option value="What is your Place of Birth?">What is your Place of Birth?</option>
</select>

在您的情况下，这可能是最简单的选择，因为您没有传递到

视图中的强类型对象。还请注意，这将适用于您发布的任何表单元素。只需将ID与
ActionResult
上的参数匹配即可

为了进一步了解这一点，您可能最好阅读关于
为每个项目指定一个值，并在模型中添加相同的值（使用相同的名称）。MVC框架将自动为您检索值。可能重复：
<select id="SomeID">
    <option value="What is your Place of Birth?">What is your Place of Birth?</option>
</select>

[HttpPost]
public ActionResult MyActionResult(string SomeID){
    // SomeID = What is your Place of Birth?
    Return View();
}
