This will work. You can read more hereabout SystemParameters
这将起作用。您可以在此处阅读有关 SystemParameters 的更多信息
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<StackPanel>
<TextBlock Text="{Binding Source={x:Static SystemParameters.FullPrimaryScreenHeight}}" />
<TextBlock Text="{Binding Source={x:Static SystemParameters.FullPrimaryScreenWidth}}" />
<TextBlock Text="{Binding Source={x:Static SystemParameters.PrimaryScreenHeight}}" />
<TextBlock Text="{Binding Source={x:Static SystemParameters.PrimaryScreenWidth}}" />
</StackPanel>
</Window>

Check out the SystemParameters class: http://msdn.microsoft.com/de-de/library/system.windows.systemparameters.fullprimaryscreenheight.aspx
查看 SystemParameters 类：http: //msdn.microsoft.com/de-de/library/system.windows.systemparameters.fullprimaryscreenheight.aspx
You can use it like this:
你可以这样使用它：
<Object Attribute="{x:Static SystemParameters.FullPrimaryScreenHeight}"/>
(You could also use the x:Static notation to query the Windows Forms properties, however if you're developing a WPF application the SystemParameters class might be the way to go)
（您也可以使用 x:Static 表示法来查询 Windows 窗体属性，但是如果您正在开发 WPF 应用程序 SystemParameters 类可能是要走的路）

Say your parent container in the XAML is grid, name it as grdForm
假设 XAML 中的父容器是网格，将其命名为 grdForm
In the code behind can get the dimensions as
在后面的代码中可以获得尺寸为
double width=grdForm.ActualWidth
双倍宽度=grdForm.ActualWidth
double height=grdForm.ActualHeight
双倍高度=grdForm.ActualHeight
