我尝试访问名为optUsoTabaco的单选按钮，代码为：

driver.FindElement(By.CssSelector("#bloco-cadastro > form > fieldset > fieldset > div:nth-child(4) > div:nth-child(2) > div.radio.md-radio > label.separador_direita.ativo"));
------ x ------        
driver.FindElement(By.XPath("//*[@id='bloco - cadastro']/form/fieldset/fieldset/div[4]/div[2]/div[1]/label[2]/input")).Click();
------ x ------        
driver.FindElement(By.XPath("//*[@id='bloco - cadastro']/form/fieldset/fieldset/div[4]/div[2]/div[1]/label[2]")).Click();
------ x ------     
IList<IWebElement> radioBtn = driver.FindElements(By.Name("optUsoTabaco"));
radioBtn.ElementAt(1).Click();

在所有这些情况下，我都收到错误："WebDriver 中发生了类型为'OpenQA.Selenium.NoSuchElementException'的异常.dll但没有在用户代码中处理。附加信息：没有此类元素：无法找到元素" 我做错了什么？

我已经尝试等待 10 秒，但它没有解决问题

Answer 1

你正在编写的所有xpath和cssSelector都是绝对的，使用起来意义不大。虽然他们是正确的。而且我认为它们没有任何问题。

我相信有 iframe/框架集 涉及，为此您必须将 Web 驱动程序的焦点切换到该特定 iframe。

您可以尝试的代码：

driver.SwitchTo().Frame(driver.FindElement(By.Xpath("xpath of frame")));

Answer 2

您可以使用CSS选择器

如果要选择Sim单选按钮，请使用

div.row > div > div > label > input[name="optUsoTabaco"][value="S"]

如果要选择 Não，请使用

div.row > div > div > label > input[name="optUsoTabaco"][value="N"]

Answer 3

我用JavaScript解决了这个问题

IWebElement st_2 = driver.FindElement(By.Name("optUsoTabaco"));
((IJavaScriptExecutor)driver).ExecuteScript("arguments[0].click();", st_2);
