MultipleViewPattern.SetCurrentView(Int32) 方法

定义

命名空间:

System.Windows.Automation

程序集:

UIAutomationClient.dll

设置当前的特定于控件的视图。

public:
 void SetCurrentView(int viewId);

public void SetCurrentView (int viewId);

member this.SetCurrentView : int -> unit

Public Sub SetCurrentView (viewId As Integer)

参数

viewId

Int32

特定于控件的视图标识符。

例外

ArgumentException

viewId 不是受支持的视图集合的成员。

示例

在下面的示例中，检索可用于支持控件模式的控件的 MultipleViewPattern 视图集合。 视图标识符集合的成员随后用于修改控件的当前视图。

private void SetView(AutomationElement multipleViewControl, int viewID)

注解

可以使用 检索 GetSupportedViews视图标识符。

特定于控件的视图标识符集合在实例之间是相同的。
