IE10和IE11中的ElementNotVisibleException

Question

我有一个为Chrome驱动程序工作的测试用例。

然后我为ie10和ie-11驱动程序（使用BrowserStack）执行它，并且它抛出一个exeception（见下文）基本上我使用

选择一个元素

IWebElement myElement = _driver.FindElement(By.XPath("//*/input[@type='file']"));

方法。我跑的时候

myElement.SendKeys(@"C:\Users\hello\Documents\images\wallpaper1.jpg");

它抛出了下面的例外。
