RangeValuePattern.RangeValuePatternInformation.Value 속성

정의

네임스페이스:

System.Windows.Automation

어셈블리:

UIAutomationClient.dll

UI 자동화 요소의 현재 값을 가져옵니다.

public:
 property double Value { double get(); };

public double Value { get; }

member this.Value : double

Public ReadOnly Property Value As Double

속성 값

Double

UI 자동화 요소의 현재 값이거나 null 요소가 지원하지 Value않는 경우입니다. 기본값은 0.0입니다.
