C# 如何使用路由获取页面上的所有iFrame？

因此，我正在创建一个

BaseIFrame

类，以便在不使用id、xpath或任何特定于DOM的东西的情况下，从任何页面通用地解析嵌套的iframe。我目前正在“路由”我的iFrame，方法是获取名称，将它们存储在字符串中，然后切片特定的iFrame名称并切换到它。我的目标是解析切片名称中的所有嵌套帧

但是，当我运行它时，我会得到a.）无限循环或b.）元素，并将哈希代码作为ID附加到字典中

我怎样才能解决这个问题

BaseiFrame

Class:

namespace [Confidental namespace] {
 public class BaseIFrame {
         protected IWebDriver _driver;

         private ReadOnlyCollection<IWebElement> _iframes;

 public BaseIFrame(IWebDriver _driver) { 
        this._driver = _driver;     
         
        _iframes = _driver.FindElements(By.TagName("frame"));             
        _iframesSize = _iframes.Count();             
     }

 public ReadOnlyCollection<IWebElement> getFrames() {
            return _iframes;
        }

        public void GetAlliFrames<T>(IWebDriver driver)
        {
            string frameRoute = "main:topMenu";

            Dictionary<string, IWebElement> returnValue = new Dictionary<string, IWebElement>();

            int startPosition = frameRoute.IndexOf("");
            string firstOuterFrameRoute = frameRoute.Substring(startPosition,
                                              frameRoute.IndexOf(":", startPosition) - startPosition);

            var firstOuterFrame = driver.FindElement(By.Name(firstOuterFrameRoute));

            driver.SwitchTo().Frame(firstOuterFrame);

            try
            {
                for (var i = 0; _iframesSize > i; i++)
                {
                    returnValue.Add(_iframes[i].ToString(), _iframes[i]);
                }
            }
            catch (Exception e)
            {
                Debug.WriteLine(e.FormatExceptionMessage(this));
                throw;
            }
            
        }
    }
}

        [TestMethod]
        public void AssertiFrameLength()
        {
            Login();

            var expected = 0;

            BaseIFrame bif = new BaseIFrame(_driver);
            bif.GetAlliFrames<IWebElement>(_driver);

            var elementSize = _driver.FindElements(By.TagName("*")).Count;

            for (var i = 0; i < elementSize; i++)
            {
                var iframesSize = _driver.FindElements(By.TagName("frame")).Count;
                expected += iframesSize;
            }

            var actual = bif.getFrames();

            Assert.AreEqual(expected, actual.Count);
        }
