访问其他应用程序窗口-WhiteStack

Question

我想测试Outlook应用程序并通过使用White Stack框架向我发送电子邮件。我实现了单击“新建项目”的代码，然后出现了新窗口。我想将我的邮件输入到“文本框”，但我不知道如何访问第二个窗口“无标题-消息（HTML）”。 Photo

    [TestMethod]
    public void mail()
    {
        var application = Application.Launch(appPatch);
        Thread.Sleep(2000);
        var window = application.GetWindow(appTitle, InitializeOption.NoCache);
       
        SearchCriteria searchCriteriaNewEmail = SearchCriteria.ByText("New Email");
        Button buttonNewEmail = window.Get<Button>(searchCriteriaNewEmail);
        buttonNewEmail.Click();


        Thread.Sleep(1000);
        string windowTitle = "Untitled‬ - Message(HTML)";
        var window2 = application.GetWindow(windowTitle, InitializeOption.NoCache);
        SearchCriteria searchCriteriaTo = SearchCriteria.ByText("To");
        TextBox tbxTo = window2.Get<TextBox>(searchCriteriaTo);
        tbxTo.BulkText = "mymail@gmail.com";

        Thread.Sleep(2000);
        window.Close();
    }
