我的控制器操作代码：
ViewBag.country = from p in CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures)
select new SelectListItem
{
Text = p.EnglishName,
Value = p.DisplayName
};
查看代码：
<dl>
<dt>
<label>
Country:
</label>
</dt>
<dd>
@Html.DropDownListFor(model => model.Country, (IEnumerable<SelectListItem>)ViewBag.country)
</dd>
<dl>
它会生成未排序语言的下拉列表。但是我需要一个下拉列表，以排序国家列表。请帮助！！！
这是您想要的吗？
ViewBag.country = from p in CultureInfo.GetCultures(CultureTypes.AllCultures & ~CultureTypes.NeutralCultures).OrderBy(c=>c.Name)
select new SelectListItem
{
Text = p.EnglishName,
Value = p.DisplayName
};
Windows和/或.Net不包含所有国家/地区的列表。
语言/文化列表很稳定，国家来来往往，或经常更改名称。
转到ISO站点，您可以从其站点download a list of countries。您必须下载此列表，并经常更新数据。
更新：国家/地区代码列表不再由ISO自由分发，更多信息can be found on the iso.org site.
[并且您必须确定是否要在该列表中包括巴勒斯坦这样的国家（巴勒斯坦在此列表中，只是“新”国家的示例）。您可能必须手动添加它们。
您可以使用此列表
