如何获取textbox或dropdownlist的值并发送到ASP.NET MVC4中的数据库

I have a dropdownlist like this:

我有一个这样的下拉列表：

var Country = new List<ListItem> 
{ 
        new ListItem { Text = "American" }, 
        new ListItem { Text = "British" } ,
        new ListItem { Text = "Spanish" }, 
        new ListItem { Text = "Persian" } ,
        new ListItem { Text = "China" },
        new ListItem { Text = "else" }
};
@Html.DropDownList("Country", new SelectList(Country))

When a user choose “else” , one textbox appears and user can type it’s country on textbox, I did this by jquery :

当用户选择“else”时，会出现一个文本框，用户可以在文本框中键入它的国家/地区，我通过jquery执行此操作：

@Html.TextBox ("txtCountry",null,new {@id="txtCountry"})

I want to define a variable to get Country from user and send to database. Filed’s name in Model is “Country”

我想定义一个变量来从用户获取Country并发送到数据库。模型中提交的名称是“国家”

How do this?

这是怎么回事？

You can get the list of form controls values using FormCollection Class. Try the below option

您可以使用FormCollection类获取表单控件值列表。请尝试以下选项

Note : Your controls should have have names (just having an id is not returning values in the formCollection)

注意：您的控件应该有名称（只是id没有返回formCollection中的值）

[HttpPost]
public ActionResult YourActionMethod(FormCollection Collection)
{
        string Country = string.Empty;

        if (Collection["txtCountry"] != null)
            Country = Collection["txtCountry"].ToString();
//Else you can assign the values to your model object.
        return View();
}
