使用c＃获取Chrome浏览器标题
假设我打开了多个镀铬窗口（不是标签），
如何查看浏览器标题？
我尝试了以下方法：
Process[] p = Process.GetProcessesByName("chrome"); foreach (Process item in p) { Console.WriteLine(item.MainWindowTitle); } 但它只返回我最后一个打开的窗口名称，所有其他都是空白..
我不得不做这样的事情，但涉及调用Windows API函数非常繁琐。 问题是Chrome似乎使用单个进程来处理多个窗口或其他一些奇怪的问题，这意味着简单的方法对我来说不起作用。
无论如何，尝试这个，看看它是否有效。 基本上，它使用Chrome窗口类名称（可能是Chrome_WidgetWin_0或Chrome_WidgetWin_1 ）来枚举具有该类名称的所有窗口，并返回非空白窗口的窗口标题。
请注意，由于某种原因，这也始终会返回名为"Chrome App Launcher"的Windows标题，因此您可能需要对其进行过滤。
注意：您也可以使用“MozillaWindowClass”为Firefox执行此操作，使用“IEFrame”对IE执行此操作（尽管其中任何一个都可能随着不同版本而更改）。

我知道这已经得到了解答，但我也提出了一个解决方案，它在一个线程中枚举了所有Windows。
它是由Matthew Watson的解决方案构建的，因此有一些相似之处。

您必须获得进程列表。
遍历列表，只在名称为“chrome”的位置。
这将允许您获得所有标题。
因为如果您有多个镀铬工艺，那么您的电话只会给您一个，因为您只需拨打一次。
它返回的可能是另一个问题。 在你的情况下，它是最后一个。
