欄位值

範例

以下範例展示了如何在 Microsoft 記事本中取得一段文字的屬性值。

private void GetAnimationStyleAttribute()
{
    // 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.AnimationStyleAttribute);
    if (oAttribute == TextPattern.MixedAttributeValue)
    {
        Console.WriteLine("Mixed animation styles.");
    }
    else
    {
        Console.WriteLine(oAttribute.ToString());
    }
}

Private Sub GetAnimationStyleAttribute()
    ' 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.AnimationStyleAttribute)
    If (oAttribute = TextPattern.MixedAttributeValue) Then
        Console.WriteLine("Mixed animation styles.")
    Else
        Console.WriteLine(oAttribute.ToString())
    End If
End Sub

備註

GetAttributeValue 回傳 TextPattern.MixedAttributeValue 以表示此變化，而非屬性值集合。

此識別碼用於 使用者介面自動化 客戶端應用程式。 使用者介面自動化提供者應該使用TextPatternIdentifiers 中的等效欄位。

使用者介面自動化 用戶端透過呼叫 GetAttributeValue 來取得該屬性的值。

此屬性的值型別為 Object。
