Window Phone 7 设备的方向

先看看WP的默认创建页面：

WP7默认创建一个横向或者竖式的显示页面。关于页面的显示有两个属性：

SupportedOrientations="Portrait" Orientation="Portrait" (竖式)

具体看看：

SupportedOrientations有三个可选项

• Portrait (the default)
• Landscape
• PortraitOrLandscape

Orientation有

• Landscape
• LandscapeLeft (tip the phone left)
• LandscapeRight (tip the phone right)
• Portrait
• PortraitDown (normal vertical position)
• PortraitUp (tip the phone upside-down)

同时WP还提供了一个事件：OrientationChanged 来监视设备方向的改变。

从上面的信息不难得出：要使页面适应设备的方向，可以设置SupportedOrientation为PortraitOrLandscape,在OrientationChanged事件设置Orientation来调整显示效果：如图
