WPF最简单程序演示数据绑定Binding

摘自《WPF深入浅出》

    <Grid>
        <Button x:Name="button" Content="Button" HorizontalAlignment="Left" Height="91" Margin="59,103,0,0" VerticalAlignment="Top" Width="406" Click="button_Click"/>
        <TextBox x:Name="textBox_1" HorizontalAlignment="Left" Height="82" Margin="59,10,0,0" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="406"/>
