如果您想禁用整个应用的纵向视图，那么您可以通过应用清单文件进行操作。

支持的旋转

对于特定页面，没有对此的内置支持，但您可以检测到旋转，然后应用变换将其旋转回来。

这是简单的演示

<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}" SizeChanged="Grid_SizeChanged_1">
    <Canvas>
        <Grid x:Name="baseGrid" RenderTransformOrigin="0.5,0.5" Background="Aqua">
            <Grid.RenderTransform>
                <CompositeTransform x:Name="baseGridRotateTransform" />
            </Grid.RenderTransform>
            <TextBlock Text="Hello World!" FontSize="50" HorizontalAlignment="Center" VerticalAlignment="Center" />
            <TextBlock Text="Hello World!" FontSize="50" Margin="914,354,-914,-354"  />
            <TextBlock Text="Hello World!" FontSize="50" Margin="112,354,-280,-354"  />
        </Grid>
    </Canvas>
</Grid>

private void Grid_SizeChanged_1(object sender, SizeChangedEventArgs e)
{
    if (Windows.UI.ViewManagement.ApplicationView.Value == Windows.UI.ViewManagement.ApplicationViewState.FullScreenPortrait)
    {
        baseGrid.Width = Window.Current.Bounds.Height;
        baseGrid.Height = Window.Current.Bounds.Width;
        baseGridRotateTransform.Rotation = 90;
        baseGridRotateTransform.TranslateX = -(Window.Current.Bounds.Height - Window.Current.Bounds.Width) / 2;
        baseGridRotateTransform.TranslateY = (Window.Current.Bounds.Height - Window.Current.Bounds.Width) / 2;
    }
    else
    {
        baseGridRotateTransform.Rotation = 0;
        baseGridRotateTransform.TranslateX = 0;
        baseGridRotateTransform.TranslateY = 0;
        baseGrid.Height = Window.Current.Bounds.Height;
        baseGrid.Width = Window.Current.Bounds.Width;
    }
}

在您的应用程序中尝试此方法

http://social.msdn.microsoft.com/Forums/en-US/winappswithcsharp/thread/82c199a0-57b1-49fe-a706-3e88b8e5148b

如果您必须控制每个页面，那么您需要在页面构造函数中使用这些行后面的代码

 Windows.Graphics.Display.DisplayProperties.AutoRotationPreferences = Windows.Graphics.Display.DisplayOrientations.Portrait
| Windows.Graphics.Display.DisplayOrientations.PortraitFlipped;

这在模拟器中不起作用，所以请不要混淆:)
