.net 5 Selenium Web驱动程序在docker容器中不工作错误:没有这样的文件或目录

Question

我在使用.net的selenium网络驱动程序时遇到问题，需要您的帮助。

我正在使用.net 5，并试图在Linux Docker容器上运行Selenium Web驱动程序；System.ComponentModel.Win32Exception没有这样的文件或目录"错误我以为chromedriver文件不存在。但我已经检查了路径是否正确，甚至我把chromeriver放在了usr/local/bin，app/文件夹中。

当我在没有码头工人的情况下跑步时，它是有效的。

我的代码：

...
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
....
var chromeOptions = new ChromeOptions();
chromeOptions.AddArgument("headless");
chromeOptions.AddArgument("no-sandbox");
chromeOptions.PageLoadStrategy = PageLoadStrategy.Eager;
// var driver = new ChromeDriver(chromeOptions);
// var driver = new ChromeDriver("/usr/local/bin/",chromeOptions); 
var driver = new ChromeDriver(AppDomain.CurrentDomain.BaseDirectory, chromeOptions);

错误：

我使用的是远程驱动程序，而不是chrome文件。
