        {
            IWebDriver driver = new FirefoxDriver();

            driver.Navigate().GoToUrl(" http://toolsqa.wpengine.com/automation-practice-form/");
            String st = "dld";
            SelectElement dropdown = new SelectElement(st);

}

Answer 1

new SelectElement()采用webElement类型的参数

您正在string作为参数传递。 更改参数类型，然后尝试 -

IWebElement element = driver.FindElement(By.your_locator);
SelectElement dropdown = new SelectElement(element);
