使用公共键将两个表连接起来，并在datagrid C＃linq上显示

Question

我需要连接一个DataGrid的两个表，但是我只想要具有相同ID的值（idviagem在表idviagem中为pk，在表idpassageiro中为fk）

我不知道如何执行查询，那一刻我只将表tbpassageiro放在网格上，并且我想在键相等时将它们加入DataGrid上

using (checkinEntities1 db = new checkinEntities1())
{

    var qcheckin = (from c in db.tbpassageiro
                    join g in db.tbviagem on c.idviagem equals g.idviagem
                    where c.idviagem == g.idviagem
                    select c).ToList();

     gridpass.ItemsSource = qcheckin;

}

我知道100％的绑定是正确的（表passiro中的某些值和表tbviagem中的其他Biding值）

这就是我想做的：

Answer 1

如果要从两个表中获取列，则必须为要从两个表中获取的列创建视图模型。

using (checkinEntities1 db = new checkinEntities1())

{

var qcheckin = (from c in db.tbpassageiro
                join g in db.tbviagem on c.idviagem equals g.idviagem
                where c.idviagem == g.idviagem
                select new viewModelName()
                {
                    //get the column values here like
                    Hora = c.Hora,
                    Partida = g.Partida
                }).ToList();

 gridpass.ItemsSource = qcheckin;

}

希望这会为您提供所需的答案。
