我绑定了来自数据库的数据ListBoxItem's,下面是代码:

public void load_users()
{
    RST_DBDataContext conn = new RST_DBDataContext();
    List<TblUser> users = (from s in conn.TblUsers
                                  select s).ToList();
    Login_Names.ItemsSource = users;
}

在XAML中,有以下代码:

<ListBox Name="Login_Names" 
         ItemsSource="{Binding Path=UserName}"
         HorizontalAlignment="Left" 
         Height="337" Margin="10,47,0,0"
         Padding="0,0,0,0" VerticalAlignment="Top" Width="156">

但它不起作用,它显示表名,但我需要看到来自表的用户名,在TblUsers中有一个名为UserName的列.

提前致谢.

我有一张桌子产品和一张桌子位置。产品表具有两列pickLocation和recLocation。在位置表中，我有id和name列。pickLocation和recLocation具有位置表中的ID。我该如何在Codeigniter中加入表格。

这是我的代码

$this->db->select("locations.name as plname");
$this->db->select("locations.name as rcname");
$this->db->join("locations","locations.id=products.pickLocation","LEFT");
$this->db->join("locations","locations.id=products.recLocation","LEFT");

这是产品表

+----+--------------+-------------+
| Id | pickLocation | recLocation |
+----+--------------+-------------+
|  1 |           12 |          23 |
|  2 |           12 |          12 |
+----+--------------+-------------+

这是位置表

+----+-----------+--+
| Id |   name    |  |
+----+-----------+--+
| 12 | Location1 |  |
| 23 | Location2 |  |
+----+-----------+--+

我想要这样的结果

+-----------------------+
| 1 Location1 Location2 |
+-----------------------+
| 2 Location1 Location1 |
+-----------------------+
