C# 无法使用chrome驱动程序85和chrome浏览器版本85初始化chrome驱动程序

当执行任何测试脚本时。chrome驱动程序未初始化并在visual studio 2019中引发null异常

  Message: 
    Test method  threw exception: 
    System.NullReferenceException: Object reference not set to an instance of an object.
    TestCleanup method  threw exception. System.NullReferenceException: System.NullReferenceException: Object reference not set to an instance of an object..
session not created: This version of ChromeDriver only supports Chrome version 83 (SessionNotCreated)

对goolge.com执行任何selenium UI测试用例

下面是我在VisualStudio2019中遇到的错误

  Message: 
    Test method  threw exception: 
    System.NullReferenceException: Object reference not set to an instance of an object.
    TestCleanup method  threw exception. System.NullReferenceException: System.NullReferenceException: Object reference not set to an instance of an object..

复制行为的详细步骤：

预期行为 chrome驱动程序应在visual studio 2019中初始化

复制此问题的测试脚本或命令集 如果 设置更复杂，GitHub repo链接也可以

   [TestInitialize]
        public static IWebDriver NavigateTo(string browser)
        {
            //accessing the web driver from the solution directory
            var currentPath = Directory.GetCurrentDirectory();
            

            try
           
                if (browser.Contains("Chrome"))
                {
             
                    ChromeOptions options = new ChromeOptions();
                    options.AddArguments(/*"--headless",*/ "--disable-gpu", "--window-size=1920,1200", "--ignore-certificate-errors", "--silent");
                    options.PageLoadStrategy = PageLoadStrategy.Default;                    

                    driver = new ChromeDriver(currentPath, options);
       
                }
       
    
 
            catch (Exception e)
            {
                _ = e.StackTrace;
            }
            return driver;
        }

环境 操作系统：Windows 10 浏览器：Chrome版本85.0.4183.83（官方版本）（64位） 浏览器版本：版本85.0.4183.83（正式版本）（64位） 浏览器驱动程序版本：ChromeDriver 85.0.4183.87

语言绑定版本：C#Visual Studio 2019

问题已解决=nuget软件包未更新chrome驱动程序，即使它显示为最新版本。nuget显示最新的chrome驱动程序正在更新。但是在bin文件夹中。这实际上是旧版本。我不得不重新启动我的VisualStudio并卸载nuget软件包，然后重新安装修复了这个问题。谢谢您的帮助

驱动程序是否在同一文件夹中？是否为c#可执行文件？我认为下面的行失败了：driver=newchromedriver（currentPath，options）；请参阅错误日志，其中提到此版本的ChromeDriver仅支持ChromeVersion83（SessionNotCreated）。因此，我认为您必须升级chrome驱动程序或降级chrome版本。@jdweng是的，它使用的是当前目录，即我的用户文件夹。我调试了它，路径显示正确。@dilimpeghwal我有最新版本的chrome浏览器版本85和chrome驱动程序版本85。我无法在这里上传我的截图。我不会的。你是在手动添加chromedriver吗？你为什么不使用nuget？
