动态Linq访问项

Question

我有一个动态LINQ查询，如下所示。

 var results=DataTable.AsEnumerable().AsQueryable()
                .Select(selectObjStr)
                .GroupBy("new (Country,City)", "it")
                .Select("new (Key.Country as Country, Key.City as City)");

导致

[0] = {Country=India, City=Bangalore}

[1] = {Country=India, City=Mangalore}

[2] = {Country=USA, City=LA}

如何从结果中访问每个关键项？我试过像

foreach(var row in results)
{
  //but row does not have key column Country or city
}

请帮帮我

Answer 1

怎么样

for(int i =0; i < results.Count();i++)
{
   results[i].Country;
}

尝试，但不确定
