备注

PKEY 值在 Propkey.h 中定义。

若要与使用介于 1 和 5 之间的值的分级系统的兼容性，请参阅属性 System.SimpleRating。 但请注意，Windows Vista Shell 中未使用 System.SimpleRating。

下表描述了 Shell UI 中使用的star分级系统在 System.Rating 值方面的含义。

System.Rating 星级评定
1-12 1 星
13-37 2 星
38-62 3 星
63-87 4 星
88-99 5 星

 

当用户通过在 UI 中选择star分级值对项目进行评分时，将分配实际的 System.Rating 值，如下表所示：

星级评定 通过 UI 分配的值
1 星 1
2 星 25
3 星 50
4 星 75
5 星 99

 

如果文件具有 System.SimpleRating 值而不是 System.Rating 值，请使用下表转换并指定 System.Rating 的值。

System.SimpleRating System.Rating
1 1
2 25
3 50
4 75
5 99

 

如果文件同时具有 System.Rating 和 System.SimpleRating 持久化值，请始终在直接请求 System.Rating 值时使用该值，而不引用 System.SimpleRating。
