构造函数

XamlSourceFocusNavigationRequest(XamlSourceFocusNavigationReason)	使用导航请求的原因初始化 XamlSourceFocusNavigationRequest 类的新实例。
XamlSourceFocusNavigationRequest(XamlSourceFocusNavigationReason, Rect)	使用导航请求和将接收导航焦点的边框的原因初始化 XamlSourceFocusNavigationRequest 类的新实例。
XamlSourceFocusNavigationRequest(XamlSourceFocusNavigationReason, Rect, Guid)	使用导航请求的原因、将接收导航焦点的边框以及请求的唯一相关 ID 初始化 XamlSourceFocusNavigationRequest 类的新实例。

属性

CorrelationId	获取导航请求的唯一标识符。 可以使用此值进行日志记录，或者，如果某个正在进行的焦点移动已有一个关联 ID，并且你想要将焦点移动与新的导航请求连接，则可以使用此值。
HintRect	获取桌面应用程序中失去焦点的元素的边框， (即 DesktopWindowXamlSource 接收焦点) 之前具有焦点的元素。
Reason	获取一个 XamlSourceFocusNavigationReason 值，该值指示导航请求的原因。
