我有绑定到 ObservableCollection 并使用文件名显示图像的列表框
我的xml是:
<Window x:Class="ThumbnailsView.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="578" WindowStartupLocation="CenterScreen">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="55"/>
</Grid.RowDefinitions>
<ListBox Grid.Row="0" x:Name="ImageListbox"
ItemsSource="{Binding}"
Background="AliceBlue" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<CheckBox Height="16" VerticalAlignment="Top" Margin="0,10,0,0"/>
<Image Margin="10,10,10,0" Height="64" Width="64" VerticalAlignment="Top">
<Image.Source>
<BitmapImage DecodePixelWidth="64" UriSource="{Binding Path=Name}"/>
</Image.Source>
</Image>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
<Button Grid.Row="1" Content="Get Images" Name="getImageBtn" Click="getImageBtn_Click" Width="100" Height="30"></Button>
</Grid>
</Window>
问题是,它会加载整个图像,如果我有大量集合,它将消耗大量内存。如何最小化它的内存消耗?
