c# - 将图像绑定到 wpf 中的列表框

Question

我在列表框中得到空白图像，我认为图像源未绑定...

.xaml 代码：

                <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapPanel FlowDirection="LeftToRight" ItemWidth="120" ItemHeight="120"/>
                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Button x:Name="b" Click="b_Click_1" Width="120" Height="120" >
                        <Image HorizontalAlignment="Left" 
                        Margin="-10,-10,-10,-10" 
                        x:Name="image1" 
                        Stretch="Fill" 
                        VerticalAlignment="Top" Source="{Binding}"
                    />
                    </Button>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

` .cs 代码：

         DirectoryInfo dir = new DirectoryInfo(@"C:\Users\sandeep ams\Documents\Images");
                FileInfo[] file = dir.GetFiles();
                ArrayList list = new ArrayList();
                foreach (FileInfo file2 in file)
                {
                    if (file2.Extension == ".JPG" || file2.Extension == ".JPEG" || file2.Extension == ".GIF" || file2.Extension == ".PNG")
                    {
                        list.Add(file2);
                    }
                }
                listBox.ItemsSource = list;

在这里，我试图将图像绑定到列表框图像源未绑定它在列表框中显示空图像。

你可以这样做：

foreach (FileInfo fileInfo in files)
{
    if (fileInfo.Extension.Equals(".JPG", StringComparison.InvariantCultureIgnoreCase) ||
        fileInfo.Extension.Equals(".JPEG", StringComparison.InvariantCultureIgnoreCase) ||
        fileInfo.Extension.Equals(".GIF", StringComparison.InvariantCultureIgnoreCase) ||
        fileInfo.Extension.Equals(".PNG", StringComparison.InvariantCultureIgnoreCase))
    {
        list.Add(fileInfo.FullName);
    }
}
