我有一个自动化测试，下面有以下代码行，用于在sendkeys之后输入searchbox：
driver.FindElement(By.XPath("//*[@id='standard-uncontrolled']")).SendKeys("@Auto");
driver.FindElement(By.XPath("//*[@id='standard-uncontrolled']")).SendKeys(Keys.Enter);
当我在调试模式下缓慢运行时，它可以完美运行。但是如果没有调试模式，Chrome在执行SendKeys(Keys.Enter)时会崩溃，并且Visual Studio会显示以下消息：
Message: Test method threw exception:
OpenQA.Selenium.WebDriverException: Unexpected error.
System.Net.WebException: Unable to connect to the remote server --->

这是我遇到问题的元素的HTML

我正在使用Chrome版本73.0.3683.86和ChromeDriver版本73.0.3683.68。
有人知道为什么会发生吗？预先感谢！
答案 0 :(得分：1)
看一些文档，看来72.0.3626.121是铬版本，与Chromedriver 72.0.3626.69不兼容。据我所知，您有两种选择：
使用Chrome版本72.0.3626.81，不要再使用chromedriver。

以上内容不是您的问题。继续...
我想我知道那条线怎么了
driver.FindElement(By.XPath("//*[@id='standard-uncontrolled']")).SendKeys(Keys.Enter);
Keys.Enter来自Keys class，首先，您必须导入（也许/可能您已经导入），但更重要的是，它只能由Actions调用。 here's SendKeys我认为您正在使用。请注意弃用警告：[Obsolete("Use the Actions or ActionBuilder class to simulate keyboard input.")]。
所以无论如何，如果您尝试以下操作，我认为它应该可以工作。
using OpenQA.Selenium.Keys
using OpenQA.Selenium.Interactions;
IWebElement standardUncontrolled = driver.FindElement(By.XPath("//*[@id='standard-uncontrolled']"));
standardUncontrolled.SendKeys("@Auto");
Actions builder = new Actions(driver);
builder.SendKeys(standardUncontrolled, Keys.Enter).Perform();
Thread.Sleep(1000);
