Public Shared ReadOnly StrikethroughStyleAttribute As AutomationTextAttribute 

Nilai Bidang

Contoh

Contoh berikut menunjukkan cara mendapatkan nilai atribut untuk rentang teks di Microsoft Notepad.

Catatan

Microsoft Notepad digunakan sebagai penyedia teks hanya untuk tujuan contoh. Microsoft Notepad tidak dijamin untuk mendukung nilai atribut yang diminta.

private void GetStrikethroughStyleAttribute()
{
    // Start application.
    Process p = Process.Start("Notepad.exe", "text.txt");

    // target --> The root AutomationElement.
    AutomationElement target = AutomationElement.FromHandle(p.MainWindowHandle);

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

    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;
    }

    Object oAttribute = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.StrikethroughStyleAttribute);
    if (oAttribute == TextPattern.MixedAttributeValue)
    {
        Console.WriteLine("Mixed strikethrough styles.");
    }
    else
    {
        Console.WriteLine(oAttribute.ToString());
    }
}
Private Sub GetStrikethroughStyleAttribute()
    ' Start application.
    Dim p As Process = Process.Start("Notepad.exe", "text.txt")

    ' target --> The root AutomationElement.
    Dim target As AutomationElement = AutomationElement.FromHandle(p.MainWindowHandle)

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

    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
    End If

    Dim oAttribute As Object = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.StrikethroughStyleAttribute)
    If (oAttribute = TextPattern.MixedAttributeValue) Then
        Console.WriteLine("Mixed strikethrough styles.")
    Else
        Console.WriteLine(oAttribute.ToString())
    End If
End Sub
