T:Windows.Storage.SystemProperties |
winrt class |
Provides string values for indexing names of common Windows file properties such as System.Title, and also references helper objects that provide indexing names for properties of specific file types (for example video files).
The scenario for using SystemProperties is when you are defining search indexes or other operations where you want the indexing to use the same name for a property that the system has already defined, as one of the Windows file properties.
Some of the SystemProperties properties return a string name directly. For example, SystemProperties.Title returns the string "System.Title". Some of the SystemProperties properties return a helper object. For example, SystemProperties.Video returns a SystemVideoProperties object. You can then use this object's properties to get the name for a video-specific Windows file property, for example SystemVideoProperties.FrameHeight returns "System.Video.FrameHeight".
