定义

命名空间:

System.Windows.Input

程序集:

PresentationCore.dll

返回一个值，该值指示当前 StylusPointDescription 是否为指定 StylusPointDescription 的子集。

public:
 bool IsSubsetOf(System::Windows::Input::StylusPointDescription ^ stylusPointDescriptionSuperset);

public bool IsSubsetOf (System.Windows.Input.StylusPointDescription stylusPointDescriptionSuperset);

member this.IsSubsetOf : System.Windows.Input.StylusPointDescription -> bool

Public Function IsSubsetOf (stylusPointDescriptionSuperset As StylusPointDescription) As Boolean

参数

stylusPointDescriptionSuperset

StylusPointDescription

要根据其检查当前 StylusPointDescription 是否为子集的 StylusPointDescription。

返回

Boolean

如果当前 StylusPointDescription 是指定 StylusPointDescription 的子集，则为 true；否则为 false。

示例

以下示例检查 是否 description2 是 的 description1子集。

StylusPointDescription description1 =
      new StylusPointDescription(new StylusPointPropertyInfo[]
