调用以上封装类里面的方法：
1、调用Apply()
在页面的Load事件里调用（.xaml.cs中的Load事件）：
K.Controls.AutoControl.Apply(content);
.xaml中内容：
<Grid Background="#00232A34">
<Viewbox>
<ContentControl x:Name="content" Width="1440" Height="1080" region:RegionManager.RegionName="{x:Static calc:RegionType.ContentRegion}"/>
</Viewbox>
<Viewbox>
<Canvas Width="{Binding ElementName=content,Path=ActualWidth}" Height="{Binding ElementName=content,Path=ActualHeight}" x:Name="canvasBorder" IsHitTestVisible="False" Visibility="Hidden">
<Image Source="{DynamicResource PracticeBack}" Stretch="Fill" Width="{Binding ElementName=content,Path=ActualWidth}" Height="{Binding ElementName=content,Path=ActualHeight}"/>
<Image Width="84" Height="56" Source="{DynamicResource PracticeDesc}" Stretch="Fill" HorizontalAlignment="Left" VerticalAlignment="Top"/>
</Canvas>
</Viewbox>
</Grid>
或者：
.xaml.cs中Load事件内容：
K.Controls.AutoControl.Apply(grid);
.xaml中内容：
<Viewbox>
<Grid x:Name="grid" Width="1440" Height="1080">
</Grid>
</ViewBox>
2、Calc()方法
var sacle = K.Controls.AutoControl.Calc();
item.BorderHeight = 1 * sacle;
3、Is1920x1080()方法---分辨率是否1920*1080
var isLarge = K.Controls.AutoControl.Is1920x1080();
if (isLarge)
{
columnpay.Width = new GridLength(670); 重新设置宽度
}
else
{
columnpay.Width = new GridLength(500);
}
.xaml中内容：
<Grid Grid.Row="3">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1.46*"/>
<ColumnDefinition Width="2"/>
<ColumnDefinition Width="1*"/>
<ColumnDefinition x:Name="columnpay" Width="706"/>
</Grid.ColumnDefinitions>
</Grid>
