public System.Windows.Automation.Text.TextPatternRange FindText (string text, bool backward, bool ignoreCase);

member this.FindText : string * bool * bool -> System.Windows.Automation.Text.TextPatternRange

Public Function FindText (text As String, backward As Boolean, ignoreCase As Boolean) As TextPatternRange

Parametri

text

String

Stringa di testo da cercare.

backward

Boolean

true se deve essere restituito l'ultimo intervallo di testo invece del primo; in caso contrario false.

ignoreCase

Boolean

true se è necessario ignorare la differenza tra maiuscole e minuscole; in caso contrario, false.

Restituisce

TextPatternRange

Intervallo di testo corrispondente al testo specificato; in caso contrario, Null (Nothing in Visual Basic).

Esempio

 private TextPatternRange TextFromSelection(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[] tprSelection = textpatternPattern.GetSelection();
    // Find 'text' in selection range
    return tprSelection[0].FindText("text", false, true);
}

Private Function TextFromSelection(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()
    ' Find 'text' in selection range
    Return currentSelection(0).FindText("text", False, True)
End Function

Commenti

Non esiste alcuna differenziazione tra testo nascosto e visibile. Automazione interfaccia utente client possono usare IsHiddenAttribute per controllare la visibilità del testo.
