无法隐式转换类型'System.Linq.IQueryable< INT>'到'廉政？“

var cityList = from country in 
                    doc.Element("result").Element("cities").Descendants("city")
select new {
        Name = country.Element("name").Value,
        Code = country.Element("code").Value,
        CountryCode = int.Parse(country.Element("countrycode").Value)
    };

foreach(var citee in cityList)
{
    City city = new City();
    city.CountryID = from cnt in db.Countries 
             where cnt.DOTWInternalID == citee.CountryCode select cnt.ID;
}

作为标题看到我得到的第二个查询错误这个帖子。我试图转换为 INT 到可空INT ，但毫无效果。帮帮我吧，伙计们。

I'm getting an error on the second query as seen in the title of this post. I tried converting to int to nullable int but nothing worked. Help me, guys.

感谢
