public string GetViewName (int viewId);

member this.GetViewName : int -> string

Public Function GetViewName (viewId As Integer) As String

参数

viewId

示例

在以下示例中，当前视图的控件特定名称是从支持 MultipleViewPattern的控件中检索的。

    }

    // Get a MultipleViewPattern from the current control.

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。

视图名称适用于文本转语音、盲文和其他辅助应用程序。
