            }

        }

尝试通过 options变量变成new FirefoxDriver()的参数.它对我来说是这样的:

FirefoxOptions options = new FirefoxOptions();
    options.BrowserExecutableLocation = ("C:\\Program Files\\Mozilla Firefox\\firefox.exe"); //This is the location where you have installed Firefox on your machine

   // WebDriver driver = new FirefoxDriver(options);

    using (var FireFoxPage = new FirefoxDriver(options))
    {
   //...

实际上，我看到一个使用 options 的注释变量对象，您在使用它时是否有任何错误？
