c# - 如何在 C# 中从谷歌浏览器版本 45 获取当前 URL？

Question

我需要在 google chrome 版本 45 中获取当前 url。

我正在搜索并获得了一些页面:

• How can I get URLs of open pages from Chrome and Firefox?

• Getting the current tab's URL from Google Chrome using C#

我需要一个最近的解决方案。最后两个解决方案在以前的 chrome 版本中可以正常工作

尝试从版本 38 或 40 到 45.x(在撰写本文时)

public string GetChormeURL(string ProcessName)
        {
            string ret = "";
            Process[] procs = Process.GetProcessesByName(ProcessName);
            foreach (Process proc in procs)
            {
                // the chrome process must have a window
                if (proc.MainWindowHandle == IntPtr.Zero)
                {
                    continue;
                }
                //AutomationElement elm = AutomationElement.RootElement.FindFirst(TreeScope.Children,
                //         new PropertyCondition(AutomationElement.ClassNameProperty, "Chrome_WidgetWin_1"));
                // find the automation element
                AutomationElement elm = AutomationElement.FromHandle(proc.MainWindowHandle);


            // manually walk through the tree, searching using TreeScope.Descendants is too slow (even if it's more reliable)
            AutomationElement elmUrlBar = null;
            try
            {
                // walking path found using inspect.exe (Windows SDK) for Chrome 43.0.2357.81 m (currently the latest stable)
                // Inspect.exe path - C://Program files (X86)/Windows Kits/10/bin/x64
                var elm1 = elm.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, "Google Chrome"));
                if (elm1 == null) { continue; } // not the right chrome.exe
                var elm2 = TreeWalker.RawViewWalker.GetLastChild(elm1); // I don't know a Condition for this for finding
                var elm3 = elm2.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, ""));
                var elm4 = TreeWalker.RawViewWalker.GetNextSibling(elm3); // I don't know a Condition for this for finding
                var elm5 = elm4.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ToolBar));
                var elm6 = elm5.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.NameProperty, ""));
                elmUrlBar = elm6.FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit));
            }
            catch
            {
                // Chrome has probably changed something, and above walking needs to be modified. :(
                // put an assertion here or something to make sure you don't miss it
                continue;
            }

            // make sure it's valid
            if (elmUrlBar == null)
            {
                // it's not..
                continue;
            }

            // elmUrlBar is now the URL bar element. we have to make sure that it's out of keyboard focus if we want to get a valid URL
            if ((bool)elmUrlBar.GetCurrentPropertyValue(AutomationElement.HasKeyboardFocusProperty))
            {
                continue;
            }

            // there might not be a valid pattern to use, so we have to make sure we have one
            AutomationPattern[] patterns = elmUrlBar.GetSupportedPatterns();
            if (patterns.Length == 1)
            {
                try
                {
                    ret = ((ValuePattern)elmUrlBar.GetCurrentPattern(patterns[0])).Current.Value;
                    return ret;
                }
                catch { }
                if (ret != "")
                {
                    // must match a domain name (and possibly "https://" in front)
                    if (Regex.IsMatch(ret, @"^(https:\/\/)?[a-zA-Z0-9\-\.]+(\.[a-zA-Z]{2,4}).*$"))
                    {
                        // prepend http:// to the url, because Chrome hides it if it's not SSL
                        if (!ret.StartsWith("http"))
                        {
                            ret = "http://" + ret;
                        }
                        return ret;
                    }
                }
                continue;
            }
        }
        return ret;
    }
