我正在尝试将JSON文件解析为ListBox，但我不知道如何这样做，并且在此处和其他地方难以理解示例。
目前，我有以下内容：
XAML
<controls:Pivot Title="Episode Guide">
<!--Pivot item one-->
<controls:PivotItem Header="season 1">
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<ListBox x:Name="Season1Box" Margin="0,0,0,0" VerticalAlignment="Top" Height="607" SelectionChanged="Season1Box_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,0">
<Image Source="{Binding Path=image1}"/>
<TextBlock Text="{Binding Path=title1}" TextWrapping="Wrap" Margin="10,10,0,0" FontSize="25" Foreground="White" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</controls:PivotItem>
<!--Pivot item two-->
<controls:PivotItem Header="season 2">
<Grid x:Name="ContentPanel2" Grid.Row="1" Margin="12,0,12,0">
<ListBox x:Name="Season2Box" Margin="0,0,0,0" VerticalAlignment="Top" Height="607" SelectionChanged="Season2Box_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,0">
<Image Source="{Binding Path=image2}"/>
<TextBlock Text="{Binding Path=title2}" TextWrapping="Wrap" Margin="10,10,0,0" FontSize="25" Foreground="White" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</controls:PivotItem>
<controls:PivotItem Header="season 3">
<Grid x:Name="ContentPanel3" Grid.Row="1" Margin="12,0,12,0">
<ListBox x:Name="Season3Box" Margin="0,0,0,0" VerticalAlignment="Top" Height="607" SelectionChanged="Season3Box_SelectionChanged">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,0">
<Image Source="{Binding Path=image3}"/>
<TextBlock Text="{Binding Path=title3}" TextWrapping="Wrap" Margin="10,10,0,0" FontSize="25" Foreground="White" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</Grid>
</controls:PivotItem>
</controls:Pivot>

public class SEASON3

public string EPISODE { get; set; }
public string TITLE { get; set; }
public string DIRECTOR { get; set; }
public string WRITER { get; set; }
public string AIRDATE { get; set; }
public string SYPNOSIS { get; set; }
public string IMAGE { get; set; }
}
public class RootObject
{
public List<SEASON1> SEASON1 { get; set; }
public List<SEASON2> SEASON2 { get; set; }
public List<SEASON3> SEASON3 { get; set; }
}
private void Season1Box_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
//To eventually navigate to another page
}
private void Season2Box_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
//To eventually navigate to another page
}
private void Season3Box_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
//To eventually navigate to another page
}
JSON文件被正确解析，我可以在这里和那里检索一些数据，但我不知道如何将它们全部放在一个ListBox中。
我试图做的是让一个ListBox显示来自JSON“TITLE”旁边的JSON的“IMAGE”。单击它们最终应该导航到包含所有其他信息的新页面，我可能会通过QueryStrings或其他东西传递所有的点点滴滴。一旦我弄明白这一点。
如果有人可以检查我的最后一点是否有意义，并指出我正确的方向为ListBox我很感激。

您应该删除SEASON2和SEASON3类，并将SEASON1重命名为Episode。序列化中不使用类名。您还应该将IMAGE - 属性更改为键入Uri，以便将其绑定到图像。
public class Episode
{
public string EPISODE { get; set; }
public string TITLE { get; set; }
public string DIRECTOR { get; set; }
public string WRITER { get; set; }
public string AIRDATE { get; set; }
public string SYPNOSIS { get; set; }
public Uri IMAGE { get; set; }
}
public class RootObject
{
public List<Episode> SEASON1 { get; set; }
public List<Episode> SEASON2 { get; set; }
public List<Episode> SEASON3 { get; set; }
}
您可以将列表绑定（或分配）到ListBox的ItemsSource属性，并根据列表中的对象填充行。每个列表项使用其对应的对象作为DataContext，您可以绑定到它们的属性。
Season1Box.ItemsSource = root.SEASON1;
Season2Box.ItemsSource = root.SEASON2;
Season3Box.ItemsSource = root.SEASON3;
要将控件的属性绑定到对象属性，可以使用语法Text="{Binding Path=MyProperty}"。您甚至可以处理嵌套属性，例如MyProperty.OtherProperty。
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal" Margin="0,0,0,0">
<Image Source="{Binding Path=IMAGE}"/>
<TextBlock Text="{Binding Path=TITLE}" TextWrapping="Wrap" Margin="10,10,0,0" FontSize="25" Foreground="White" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
