我想在一个scrollviewer中有文本块和超链接按钮,但是它说属性内容被设置多次...

        <!--ContentPanel - place additional content here-->

            <ScrollViewer>
                <TextBlock HorizontalAlignment="Left" Margin="1,15,0,85" Width="460" Height="1500" Name="TextBlock1" TextWrapping="Wrap">

private void zoom_out(object sender, RoutedEventArgs e)

            image1.Height -= 50;
            image1.Width -= 50;
            j--;
            i = j;
        }
    }
private void zoom_in(object sender, RoutedEventArgs e)
    {
       if(i<2)
        {
            image1.Height += 50;
            image1.Width += 50;
            i++;
            j = i;
        }
    }

并为.vb代码更改"j"和"i".它是用于缩小和缩小的代码.
