你可以像下面这样将 `Dictionary<string, DownloaderItem>` 类型的 `downloaderItems` 字典集合绑定到 WPF ListBox 控件:
1. 首先,在 XAML 文件中定义 ListBox 控件:
```xml
<ListBox x:Name="myListBox" />
```
2. 在代码中设置 ListBox 的数据源为 `downloaderItems` 字典集合:
```csharp
Dictionary<string, DownloaderItem> downloaderItems = new Dictionary<string, DownloaderItem>();
// 添加数据到字典集合中
// ...
myListBox.ItemsSource = downloaderItems;
```
3. 接下来,定义 ListBox 的 ItemTemplate,以便在列表中为每个字典项显示数据。可以使用 StackPanel 或 Grid 布局控制显示的元素,例如下面的示例使用 Grid 布局,将字典项的 Key 和 Value 显示在两个列中:
```xml
<ListBox x:Name="myListBox">
<ListBox.ItemTemplate>
<DataTemplate>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Text="{Binding Key}" Grid.Column="0" />
<TextBlock Text="{Binding Value}" Grid.Column="1" />
</Grid>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
```
这样,当你运行程序时,ListBox 将会显示字典集合中的所有项。每个项都将显示为一个 Grid,其中第一列显示字典项的 Key,第二列显示字典项的 Value。
