c# - 国家/地区显示名称和代码的下拉列表

Question

有人可以给我一个示例或教程，其中显示国家及其代码的下拉列表我的代码显示错误的新西兰语言代码，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));         
    }   

}

例如

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

Answer 1

您正在排除 RegionInfo.EnglishName，删除 ! 并尝试 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); 
    } 
}
