I am populating a list using

```
List<Country> countries = new List<Country> 
{ 
   new Country() 
   {
      CountryID = "US",
      City = new List<City>
      {
         new City()
         {
            CountryID = "US", CityName = "dfdsf", sqkm = 2803
         }
      }
   }
};

```

and so on

How to access **sqkm** in the following query?

```
var countryQuery = countries
    .Select(c => new { Id = c.CountryId, Area = c.City.sqkm???});

```

`c.city.sqkm` gives compilation error...how to modify query
