我有以下代码:
var ent = new DataSource(new Uri("http://abc.com/Service.svc"));
ent.Credentials = new NetworkCredential("username", "password");
var query = ent.Rentals.Execute();
var result = query.ToList();

var query = ent.Rentals.Execute() join ent.Agents.Execute() join ent.Files.Execute() ;
怎么做?
请建议。
