c#从firefox获取URL，但不使用DDE

本文关键字：DDE firefox 获取 URL | 更新日期: 2023-09-27 18:04:06

对于在firefox中检测URL，我使用DDE

 DdeClient dde = new DdeClient("Firefox", "WWW_GetWindowInfo");
 dde.Connect();
 string url1 = dde.Request("URL", int.MaxValue);
 dde.Disconnect();
 temp = url1.Replace("'"", "").Replace("'0", "");
 dde = null;

这段代码工作完美!，但是连接太慢(dde.Connect();)太慢7/8秒!是否有其他方法从firefox获取url ?(例如使用API窗口，如"SendMessage")

这个很适合我:

                AutomationElement element = AutomationElement.FromHandle(intPtr);  // intPtr is the MainWindowHandle for FireFox browser
                element = element.FindFirst(TreeScope.Subtree,
                      new AndCondition(
                          new PropertyCondition(AutomationElement.NameProperty, "Search or enter address"),
                          new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Edit)));
                string url = ((ValuePattern)element.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;

            Process[] process = Process.GetProcessesByName("firefox");
            foreach (Process firefox in process)
            {
                // the chrome process must have a window
                if (firefox.MainWindowHandle == IntPtr.Zero)
                {
                    return null;
                }
                AutomationElement element = AutomationElement.FromHandle(firefox.MainWindowHandle);
                if (element == null)
                    return null;
                //search for first custom element
                AutomationElement custom1 = element.FindFirst(TreeScope.Descendants,
                 new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Custom));
                //search all custom element children
                AutomationElementCollection custom2 = custom1.FindAll(TreeScope.Children, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Custom));
                //for each custom child
                foreach (AutomationElement item in custom2)
                {
                    //search for first custom element
                    AutomationElement custom3 = item.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Custom));
                    //search for first document element
                    AutomationElement doc3 = custom3.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document));

                    if (!doc3.Current.IsOffscreen)
                    {
                        url = ((ValuePattern)doc3.GetCurrentPattern(ValuePattern.Pattern)).Current.Value as string;
                        return url;
                    }                      
                }
            }             
            return url;
   }
