国家显示名称和代码的下拉列表

Question

某人是否可以向我展示一个示例或教程，显示国家及其代码的下拉列表 我的代码显示新西兰的错误语言代码，它显示mi-NZ而不是en- NZ

ASP.NET

protected void Page_Load(object sender, EventArgs e)  { 

    SortedDictionary<string, string> objDic = 
      new SortedDictionary<string, string>();      

    foreach (CultureInfo ObjectCultureInfo in CultureInfo.GetCultures(CultureTypes.SpecificCultures))   
    {    
     RegionInfo objRegionInfo = new RegionInfo(ObjectCultureInfo.Name);    
     if(!objDic.ContainsKey(objRegionInfo.EnglishName)) {      
      objDic.Add(objRegionInfo.EnglishName, ObjectCultureInfo.Name); 
     }   
    } 

    foreach (KeyValuePair<string, string> val in objDic) 
    {    
     ddlCountries.Items.Add(new ListItem(val.Key, val.Value));   
    } 

} 

如

United States(en-US) 
New Zealand(en-NZ) 
China(zh-CN) 

Answer 1

您排除RegionInfo.EnglishName，取出!和尝试CultureTypes.AllCultures：

foreach (CultureInfo ObjectCultureInfo in CultureInfo.GetCultures(CultureTypes.AllCultures))   
{    
    RegionInfo objRegionInfo = new RegionInfo(ObjectCultureInfo.Name); 
    if(objDic.ContainsKey(objRegionInfo.EnglishName)) {      
     objDic.Add(objRegionInfo.EnglishName, ObjectCultureInfo.Name); 
    } 
}
