>我正在使用最新的Selenium.WebDriver NuGet包v3.141.0

最新的Selenium.WebDriver.ChromeDriver软件包v80.0.3987.1600

我的Chrome版本是80.0.3987.87

ChromeDriver.exe 与我的程序可执行文件位于同一文件夹中

var driver = new ChromeDriver();
driver.Navigate().GoToUrl("https://www.google.com/");

编辑： 我也试过

IWebDriver driver;
using (driver = new ChromeDriver())
{
driver.Navigate().GoToUrl(@"https://www.google.com/");
}

失败并出现相同的错误，并尝试了IE和Firefox驱动程序

更新：

所以我在家里(不是在我的公司网络上(尝试了这个，它适用于这个确切的代码......我被防火墙阻止了吗？

Answer 1

你必须处理几件事：

• 您需要传递整个url，即将www添加到https://google.com中，因此有效地将urlhttps://www.google.com/。
• 此外，由于您已将ChromeDriver的实例初始化为driver，因此您必须仅使用驱动程序实例调用Navigate()，而不能使用drive调用。

• 实际上，您的代码块将是：

  var driver = new ChromeDriver();
  driver.Navigate().GoToUrl("https://www.google.com/");
