如何在没有c#数据库的情况下填写DropDown中的状态列表

本文关键字：DropDown 列表 状态 情况下 数据库 | 更新日期: 2023-09-27 17:58:58

Ii想在不使用数据库的情况下用状态列表填充下拉列表

我用以下代码填写了国家/地区下拉列表

 RegionInfo Countries = new RegionInfo(new CultureInfo("en-us",false).LCID);
            List<string> CountryNames = new List<string>();
            foreach (CultureInfo cul in CultureInfo.GetCultures(CultureTypes.SpecificCultures))
            {
                Countries = new RegionInfo(new CultureInfo(cul.Name,false).LCID);
                CountryNames.Add(Countries.DisplayName.ToString());
            }
            IEnumerable CountryNamesAdded = CountryNames.OrderBy(names => names).Distinct();
            foreach (string items in CountryNamesAdded)
            {
                DrdCountryList.Items.Add(items);
            }

有人能告诉我如何在不使用数据库的情况下获得无状态列表吗

或者另一个选项是从这里提到的web服务获取列表

嗨，试试这个这将填充没有数据库的国家

  List<string> objcountries = new List<string>();
            CultureInfo[] objculture = CultureInfo.GetCultures(CultureTypes.SpecificCultures);
            foreach (CultureInfo getculture in objculture)
            {
                RegionInfo objregion = new RegionInfo(getculture.LCID);
                string ss = getculture.DisplayName;
                if (!(objcountries.Contains(objregion.EnglishName)))
                {
                    objcountries.Add(objregion.EnglishName);
                }
            }
            objcountries.Sort();
            comboBox1.DataSource = objcountries;
