Linq 读取简单的XML数据

在项目开发中常用到这些,记录下来,以后忘记了,来查询

public class XmlCountryRepository : ICountryRepository
    {
        private static List<CountryData> countryList = null;

        static XmlCountryRepository()
        {
            XDocument loadedData = XDocument.Load("CountriesXML.xml");

            var data = from query in loadedData.Descendants("Country")
              select new CountryData
              {
                  Name = (string)query.Element("Name"),
                  Flag = (string)query.Element("Flag"),
                  Description = (string)query.Element("Description"),
                  Capital = (string)query.Element("Capital"),
                  ID = (int)query.Element("ID"),
              };
            countryList = data.ToList();
        }

        public IList<CountryData> GetCountryList()
        {
            return countryList;
        }

        public CountryData GetCountryById(int id)
        {
            return countryList.FirstOrDefault(c => c.ID == id);
        }
    }
