我已将单个项目添加到ItemsSource这是一个文件夹路径，所有图片都会添加到ListBox中，但我想使用相同的{{{}}将更多项目添加到现有ListBox中1}}怎么做？
ItemsSource但只有List<string> folders = new List<string>();
private void ComboBox1_Loaded(object sender, RoutedEventArgs e)
{
folders.AddRange(Directory.EnumerateFiles(@"C:\Users\images1", "*.*").ToList());
imageItems.ItemsSource = folders;
}
private void ComboBox2_Loaded(object sender, RoutedEventArgs e)
{
folders.AddRange(Directory.EnumerateFiles(@"C:\Users\images2", "*.*").ToList());
imageItems.ItemsSource = folders;
}
<ListBox x:Name="imageItems" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel IsItemsHost="True" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Image Source="{Binding}" Width="120" Height="120"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ListBox>
项被添加并显示为ComboBox2_Loaded
我怎样才能得到这两个项目？

您需要创建一个可以更改的列表，以便将文件名存储在：
ObservableCollection<string> folders = new ObservableCollection<string>();
从那里，您可以添加和删除所需的所有项目：
imageItems.ItemsSource = folders;
foreach (string file in Directory.EnumerateFiles(@"C:\Users\images1", "*.*"))
{
folders.Add(file);
}
foreach (string file in Directory.EnumerateFiles(@"C:\Users\images2", "*.*"))
{
folders.Add(file);
}
