ChromeDriver does not exist in Selenium WebDriver C# test script

Question

I have come across a few people with the same issue that seemed to have solved the problem with System.addProperty(\"webdriver.chrome.driver\", \".../chromedriver.exe\");<

Answer 1

you may have enum for your all drivers : 
  public enum Drivers
    {
        Chrome,
        Firefox,
        Safari,
        Edge,
        IE
    }


  public static IWebDriver GetDriver(Drivers driver)
        {

outPutDirectory -> is a location where all supporting dlls and files are copied when you build the solution. example : C:\Users\Mike\source\repos\Automation\Automation\bin\Debug

     var outPutDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
     // below is my location where I copied all drivers like chromedriver.exe 

relativePath -> is a one of folder being copied when you build soltuion exampple : C:\Users\Mike\source\repos\Automation\Automation\bin\Debug\BrowserDriver

        var relativePath = @"..\..\bin\Debug\BrowserDriver"; 

//So 'chromeDriverPath' will give you exact location of your driver no matter which machine or PC you are running Automation

       var chromeDriverPath = Path.GetFullPath(Path.Combine(outPutDirectory,relativePath));
    // return this driver , just debug this code and check the "outPutDirectory" path
       return new ChromeDriver(chromeDriverPath);
   }
