Rakitan:

public:
 System::Windows::Automation::Text::TextPatternRange ^ FindText(System::String ^ text, bool backward, bool ignoreCase);

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

Parameter

text

String

String teks yang akan dicari.

backward

Boolean

true jika rentang teks terakhir yang muncul harus dikembalikan alih-alih yang pertama; jika tidak false.

ignoreCase

Boolean

true jika kasus harus diabaikan; jika tidak false.

Mengembalikan

TextPatternRange

Rentang teks yang cocok dengan teks yang ditentukan; jika tidak null (Nothing dalam Visual Basic).

Contoh

 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
