Answer 1

Try:

var resultado =  
    from a in Autonomo 
    join c in Centro on a.Codigo_Centro equals c.Codigo 
    select new { a.Codigo,c.Capacidad,c.Dia,c.jefe}; 

To print:

foreach (var item in resultado) 
{  
    Console.WriteLine(item.Codigo + ", " + item.Capacidad);   
} 

Answer 2

just FYI other answer is missing where clause.don't forget where clause

var query =  from a in Autonomo 
             join c in Centro 
             on a.Codigo_Centro equals c.Codigo
             where a.Codigo_PC == 1022
             select new { a.Codigo,c.Capacidad,c.Dia,c.jefe};
