c# - 如何从 C# 中的 CultureTypes 对象获取对值？

Question

我创建了 IEnumerable 的单个对象 想要使其成为字典类型对象来处理键和值。

想要从文化中提取货币符号和名称。

 IEnumerable<string> currencySymbols = CultureInfo.GetCultures(CultureTypes.SpecificCultures) //Only specific cultures contain region information
            .Select(x => (new RegionInfo(x.LCID)).ISOCurrencySymbol )
            .Distinct()
            .OrderBy(x => x);
            foreach(string s in currencySymbols)
            {
                CurrencyTable tbl = new CurrencyTable();
                tbl.Iso = s;
                tbl.Name = s;
            }

我想要像下面这样的

IEnumerable<string,string> 

怎么可能？ CurrencyTable 是一个包含 ID | 的类。异|姓名 已提交

这个返回所有货币符号及其第一个不同的英文货币名称

var currencySymbols =
        CultureInfo.GetCultures(CultureTypes.SpecificCultures) //Only specific cultures contain region information
       .Select(x => new RegionInfo(x.LCID))
       .GroupBy(x => x.ISOCurrencySymbol)
       .Select(x => new CurrencyTable() {
            Iso = x.Key,
            Name = x.Select(y => y.CurrencyEnglishName).Distinct().FirstOrDefault()
        });

这是 LINQ 版本:

var symbols = from x in CultureInfo.GetCultures(CultureTypes.SpecificCultures)
                  let region = new RegionInfo(x.LCID)
                  group region by region.ISOCurrencySymbol into g
                  let names = from r in g select r.CurrencyEnglishName
                  select new CurrencyTable() {
                      Iso = g.Key,
                      Name = names.FirstOrDefault()
                  };
