Linq 联合查询 不能绑定到 ListBox
var query = from o in UserModel.GetInstance().DB.DBUsers
join p in UGroupModel.GetInstance().DB.DBUGroups
on o.ID equals p.ID
select new
{
o.ID,
o.Name,
o.Age,
p.Desc
};
//var query = from UGroupTable user in UGroupModel.GetInstance().DB.DBUGroups
// select user; //使用这句话可以成功绑定到ListBox
int RecCount = query.Count(); //这里的RecCount是大于0的，证明读到值了
foreach (var t in query)
{ //这里也能看到t里是有值的
}
listBox3.ItemsSource = query.ToList();
<ListBox Height="Auto" HorizontalAlignment="Left" Margin="0,300,0,0" Name="listBox3" VerticalAlignment="Top" Width="Auto">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=ID}"/>
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Path=Name}"/>
<TextBlock Text="{Binding Path=Age}" />
<TextBlock Text="{Binding Path=Desc}" />
</StackPanel>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
