    EmailAddress = results.EmailAddress,
    Keywords = results.Keywords,
    Country = results.Country,

    miles = results.Miles.ToString(),
    IsActive=results.IsActive.ToString()

};
string country= (new  ObservableCollection<Agentlist>(res))[0].Country);

please give me the soluttion

If you expect multiple results from the query try this:

// Calling ToList will force query execution.
List<Agentlist> result = res.ToList<Agentlist>();

// Calling First will take the first item in the collection.
// If there are more than one item it will NOT throw 
// an exception (calling Single() will).
Agentlist agent = result.First<Agentlist>();

string country = agent.Country;

If you need only the first result of the query you can try calling First() right away:

Agentlist agent = res.First<Agentlist>();
