我找不到可以解决此问题的答案。我有一个 ObservableCollection
这是我的班级：
public class myClass
{
public string name;
public int[] dimensions = new int[2];
}
这是设置 ObservableCollection 的代码：
public class roomBuilder
{
private ObservableCollection<myClass> rooms;
public roomBuilder() //constructor
{
string roomName;
int[] dimensions = new int[2];
myClass newRoom = new myClass();
rooms = new ObservableCollection<room>();
roomName = "Hall";
dimensions[0] = 10;
dimensions[1] = 12;
newRoom.name = roomName;
newRoom.dimensions = dimensions;
rooms.Add(newRoom);
roomListBox.DataContext = rooms;
}
用于此的 XAML 是：
<ListBox Canvas.Left="-1" Canvas.Top="47" Height="419" Name="roomListBox" Width="481" BorderThickness="1" BorderBrush="GhostWhite" ItemsSource="{Binding}" DataContext="{Binding}">
<ListBox.ItemTemplate >
<DataTemplate >
<StackPanel Orientation="Vertical" Margin="1" Name="verstack" >
<StackPanel Orientation="Horizontal" Margin="1" KeyDown="StackPanel_KeyDown" >
<TextBox Text="{Binding Path=name}" IsReadOnly="False" FontFamily="Courier New" FontSize="22" Height="65" VerticalAlignment="Top" TextAlignment="Center"/>
<TextBox Name="xDimension" Text="{Binding Mode=TwoWay, Path=dimensions[0] }" Width="70" Height="65" VerticalAlignment="Top" IsReadOnly="False" FontFamily="Courier New" Margin="2,0,1,0" FontSize="22" MaxLength="3" InputScope="TelephoneNumber" TextAlignment="Center" />
<TextBlock Name="separator" Text=":" FontSize="32" FontWeight="ExtraBold" Margin="1,4,1,0" />
<TextBox Name="yDimension" Text="{Binding Mode=TwoWay, Path=dimensions[1] }" Width="70" Height="65" VerticalAlignment="Top" IsReadOnly="False" FontFamily="Courier New" Margin="1,0,2,0" FontSize="22" MaxLength="3" InputScope="TelephoneNumber" TextAlignment="Center"/>
我还没有在这里关闭 Xaml，它下面还有更多负载，当我运行它时没有显示任何内容，我只是不知道问题是什么，我已经敲了 2 天，请有人帮忙
