MultipleViewPattern.MultipleViewPatternInformation.GetSupportedViews 方法

定義

命名空間:

System.Windows.Automation

組件:

UIAutomationClient.dll

擷取控制項特定檢視識別項的集合。

public:
 cli::array <int> ^ GetSupportedViews();

public int[] GetSupportedViews ();

member this.GetSupportedViews : unit -> int[]

Public Function GetSupportedViews () As Integer()

傳回

Int32[]

識別 AutomationElement 可用檢視之整數值的集合。 預設值為空白的整數陣列。

範例

在下列範例中，會取得整數識別碼的集合，代表支援 MultipleViewPattern 的控制項可用的檢視。

備註

檢視識別碼的集合在實例之間相同。

檢視識別碼值可以傳遞至 GetViewName 。
