WP7中Button的Image背景图片路径获取

<Button Grid.Row="1" Height="201" HorizontalAlignment="Left" Margin="198,13,0,0" Name="button3"
VerticalAlignment="Top" Width="215" Grid.ColumnSpan="2" BorderThickness="0" Click="button3_Click">
<Button.Background>
<ImageBrush ImageSource="/MyHometown;component/photos/4.jpg" Stretch="Fill" />
</Button.Background>
</Button>

获得背景图片地址，然后在其他页面使用。

private void button1_Click(object sender, RoutedEventArgs e)
{
ImageBrush i = button1.Background as ImageBrush; //background属性是Brush类 转换成ImageBrush因为图片的ImageSource是ImageBrush类。。。
BitmapImage ii = i.ImageSource as BitmapImage; // BitmapImage类中有UriSource属性，该属性就是图片的相对地址，而ImageBrush的ImageSource属性是父类是BitmapImage，转换一下就OK
txtText.Text = ii.UriSource.ToString(); //得到图片地址，或保存在变量中
}
