无法在selenium c＃中的上下文菜单中选择选项

Question

如何从上下文单击/上下文菜单中选择选项？

我可以右键单击特定元素，但无法选择任何选项。以下是我的代码：

IWebDriver driver = new FirefoxDriver();
driver.Url = "https://www.flipkart.com";
IWebElement ele = driver.FindElement(By.Name("q"));
ele.SendKeys("shoes");
Actions a = new Actions(driver);
a.ContextClick(ele).SendKeys(Keys.ArrowUp).SendKeys(Keys.Enter).Perform();
