我希望能够遍历chrome页面上的所有选项卡并关闭任何youtube页面的选项卡。
我做了一些谷歌搜索并找到了下面的代码。有两个（可能更多）问题。首先，我创建了一个WPF应用程序并添加了System.Windows.Automation命名空间（使用visual studio 2015 .net 4.5），但无法识别AutomationElement。
此外，我不确定如何循环选项卡并测试页面是否是youtube页面。
Process[] procsChrome = Process.GetProcessesByName("chrome");
if (procsChrome.Length <= 0)
return null;
foreach (Process proc in procsChrome)
{
// the chrome process must have a window
if (proc.MainWindowHandle == IntPtr.Zero)
continue;
// to find the tabs we first need to locate something reliable - the 'New Tab' button
AutomationElement root = AutomationElement.FromHandle(proc.MainWindowHandle);
var SearchBar = root.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Address and search bar"));
if (SearchBar != null)
{
AutomationPattern[] patterns = SearchBar.GetSupportedPatterns();
if(patterns.Length > 0)
{
ValuePattern val = (ValuePattern)SearchBar.GetCachedPattern(patterns[0]);
if (val.Current.Value.Contains("youtube.com") || val.Current.Value.Contains("youtube.co.uk"))
proc.Close();
}
}
}
System.Windows.Automation在UIAutomationClient.dll中。您是否添加了UIAutomationClient.dll作为项目的参考？
检查值“youtube”。
if (SearchBar != null)
{
AutomationPattern[] patterns = SearchBar.GetSupportedPatterns();
if (patterns.Length > 0)
{
ValuePattern val = (ValuePattern)SearchBar.GetCurrentPattern(patterns[0]);
if(val.Current.Value.Contains("youtube.com"))
proc.Close();
}
}
根据你的问题，我写了一个小程序来实现这个目标。如果有效，请告诉我。

仅使用YouTube杀死Chrome标签并不能解决实际问题。我认为迫使所有工作站进入睡眠状态会更容易，也更可靠。
来自的东西 这个帖子 应该做的伎俩。
rundll32.exe powrprof.dll,SetSuspendState 0,1,0 也许？
使用AutoHotkey可以轻松完成
这是一个打开Chrome的脚本，循环显示所有标签并关闭YouTube，然后再次最小化Chrome
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
