将数据触发器XAML转换为C＃

Question

<Image Width="16">
    <Image.Style>
        <Style TargetType="{x:Type Image}">
            <Style.Triggers>
                <DataTrigger Binding="{Binding Value}" Value="False">
                    <Setter Property="Source" Value="Resources/image1.png"/>
                </DataTrigger>
                <DataTrigger Binding="{Binding Value}" Value="True">
                    <Setter Property="Source" Value="Resources/image2.png"/>
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </Image.Style>
</Image>

Referring to the XAML code above, I'm confused in how to convert it to XAML, for example the Data Trigger part, anyone has any idea?

Thanks.

After little refactor, I think u need this:

Style style = new Style(typeof(Image));

// Style Setter to handle 'false' case
style.Setters.Add(new Setter(Image.SourceProperty, new BitmapImage(new Uri("Resources/image2.png", UriKind.Relative))));

// DataTrigger to handle 'true' case
DataTrigger dataTrigger = new DataTrigger();
dataTrigger.Binding = new Binding("Value");
dataTrigger.Value = true;
dataTrigger.Setters.Add(new Setter(Image.SourceProperty, new BitmapImage(new Uri("Resources/image1.png", UriKind.Relative))));
style.Triggers.Add(dataTrigger);

this.image.Style = style;
