TextPatternRange.Clone 메서드

정의

네임스페이스:

System.Windows.Automation.Text

어셈블리:

UIAutomationClient.dll

원래 TextPatternRange와 동일하고 원본의 모든 속성을 상속하는 새 TextPatternRange를 검색합니다.

public:
 System::Windows::Automation::Text::TextPatternRange ^ Clone();

public System.Windows.Automation.Text.TextPatternRange Clone ();

member this.Clone : unit -> System.Windows.Automation.Text.TextPatternRange

Public Function Clone () As TextPatternRange

반환

TextPatternRange

새 텍스트 범위입니다. null 참조(Visual Basic의 경우 Nothing)는 반환되지 않습니다.

예제

private TextPatternRange CloneSelection(AutomationElement target)
{
    // Specify the control type we're looking for, in this case 'Document'
    PropertyCondition cond = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document);

    // target --> The root AutomationElement.
    AutomationElement textProvider = target.FindFirst(TreeScope.Descendants, cond);

    TextPattern textpatternPattern = textProvider.GetCurrentPattern(TextPattern.Pattern) as TextPattern;

    if (textpatternPattern == null)
    {
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.");
        return null;
    }
    TextPatternRange[] currentSelection = textpatternPattern.GetSelection();
    return currentSelection[0].Clone();
}

Private Function CloneSelection(ByVal target As AutomationElement) As TextPatternRange
    ' Specify the control type we're looking for, in this case 'Document'
    Dim cond As PropertyCondition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)

    ' target --> The root AutomationElement.
    Dim textProvider As AutomationElement = target.FindFirst(TreeScope.Descendants, cond)

    Dim textpatternPattern As TextPattern = CType(textProvider.GetCurrentPattern(TextPattern.Pattern), TextPattern)

    If (textpatternPattern Is Nothing) Then
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.")
        Return Nothing
    End If
    Dim currentSelection As TextPatternRange() = textpatternPattern.GetSelection()
    Return currentSelection.Clone(0)
End Function

설명

또는 새를 만들 DocumentRange 에서 TextPattern 원래 텍스트 범위의 엔드포인트을 사용 하 여 해당 하는 두 개의 엔드포인트을 이동 합니다.

새 범위를 원본에서 독립적으로 조작할 수 있습니다.
