C＃すべてのタブからChrome URLを取得する

Question

こんにちは、ブラウザからURLを取得したいと思います。これらを使用していますが、null例外が発生していません。私はChromeが何かを変更したと思います。 https://stackoverflow.com/a/21799588/5096993 https://social.msdn.microsoft.com/Forums/vstudio/en-US/39bf60a8-2bdc-4aa0-96fb-08dca49cdb06/c-get-all-chrome-urls-opened?forum=csharpgeneral

最近、同じ問題が解決されましたSystem.Windows.For ms.SendKeys あなたの結果と比較して4倍高速ですが、ctrl + lホットキー（たとえば、編集モードのStackOwerflow）を使用するWebサイトでは機能しません。 ニーズに依存します:)

public void WithSendkeys() 
    { 
     AutomationElement.RootElement 
      .FindFirst(TreeScope.Children, new PropertyCondition(AutomationElement.ClassNameProperty, "Chrome_WidgetWin_1")) 
      .SetFocus(); 
     SendKeys.SendWait("^l"); 
     var elmUrlBar = AutomationElement.FocusedElement; 
     var valuePattern = (ValuePattern) elmUrlBar.GetCurrentPattern(ValuePattern.Pattern); 
     Console.WriteLine(valuePattern.Current.Value); 
    }
