我正在使用以下代码尝试获取所有托盘图标,包括Windows 10。
。 public static List<AutomationElement> EnumNotificationIcons()
{
var data = new List<AutomationElement>();
foreach (var button in AutomationElement.RootElement.Find(
"User Promoted Notification Area").EnumChildButtons())
{
data.Add(button);
}
foreach (var button in AutomationElement.RootElement.Find(
"System Promoted Notification Area").EnumChildButtons())
{
data.Add(button);
}
var chevron = AutomationElement.RootElement.Find("Notification Chevron");
if (chevron != null && chevron.InvokeButton())
{
foreach (var button in AutomationElement.RootElement.Find(
"Overflow Notification Area").EnumChildButtons())
{
data.Add(button);
}
}
return data;
}
但是,返回的列表仅包括可见图标。任何隐藏的东西都跳过了。隐藏的托盘图标不会返回。
我在这里缺少什么?
编辑:
我已经更新了代码,看起来像这样。仍然没有拉出隐藏的图标。https://blogs.msdn.microsoft.com/oldnewthing/20141013-00/?p=43863
public static IEnumerable<AutomationElement> EnumNotificationIcons()
{
var userArea = AutomationElement.RootElement.Find("User Promoted Notification Area");
if (userArea != null)
{
foreach (var button in userArea.EnumChildButtons())
{
yield return button;
}
foreach (var button in userArea.GetTopLevelElement().Find("System Promoted Notification Area").EnumChildButtons())
{
yield return button;
}
}
var chevron = AutomationElement.RootElement.Find("Notification Chevron");
if (chevron != null && chevron.InvokeButton())
{
foreach (var button in AutomationElement.RootElement.Find("Overflow Notification Area").EnumChildButtons())
{
yield return button;
}
}
}
我能够与以下代码一起使用此功能。我不得不强迫等待它出现。
/// <summary>
/// Enums the notification icons in the Tray.

if (userArea != null)
{
foreach (var button in userArea.EnumChildButtons())
{
yield return button;
}
foreach (var button in userArea.GetTopLevelElement().Find(UINotificationAreaConstants.SystemPromotedNotificationArea).EnumChildButtons())
{
yield return button;
}
}
var chevron = AutomationElement.RootElement.Find(UINotificationAreaConstants.NotificationChevron);
if (chevron != null && chevron.InvokeButton())
{
var elm = AutomationElement.RootElement.Find(
UINotificationAreaConstants.OverflowNotificationArea);
WaitForElm(elm);
foreach (var button in elm.EnumChildButtons())
{
yield return button;
}
}
}

private static WindowPattern WaitForElm(AutomationElement targetControl)
{
WindowPattern windowPattern = null;
try

windowPattern =
targetControl.GetCurrentPattern(WindowPattern.Pattern)
as WindowPattern;
}
catch (InvalidOperationException)
{
// object doesn't support the WindowPattern control pattern
return null;
}
// Make sure the element is usable.
if (!windowPattern.WaitForInputIdle(10000))
{
// Object not responding in a timely manner
return null;
}
return windowPattern;
}
