how to return anonymos data type in select with sqllite.net?

i have a sqllite database that use it in xamarin android. i want to select 2column of 2table that joined it. how return query result without create a model class?

var query = select tbl1.Key,tbl2.value from tbl1 inner join tbl2 on tbl1.id==tbl2.id

and code:

var con= new SQLiteConnection();
....
Dictionary<string,string> result=con.Query<????>(query);

how do this without "create model class and then convert list to dictionary"?
