Setting up relative path for the gecko driver on selenium with c#

I have to check what was the currant location which my test is going to execute. Actually i was thinking that is inside the bin folder but i was wrong.

 string value = AppDomain.CurrentDomain.BaseDirectory;

From this you can get the actual location where your test project is building right now.

in my case it is on E:\\Users\\<user>\\documents\\visual studio 2012\\Projects\\TestWithSelenium3\\TestResults\\cja_ES-NB-110 2017-01-18 22_43_22\\Out

Then based on the above location i have to give the relative path. My Gecko driver was inside the TestWithSelenium3 folder so i have to move back 3 time as below.

@"..\..\..\TestWithSelenium3"

Then it works,

FInal test method will looks like :

 [TestMethod]

        public void CodedUITestMethod1()

        {

            var path = Application.CommonAppDataPath;

            string value = AppDomain.CurrentDomain.BaseDirectory;

            FirefoxDriverService service = FirefoxDriverService.CreateDefaultService(@"..\..\..\TestWithSelenium3", "geckodriver.exe");

            IWebDriver driver = new FirefoxDriver(service);

            driver.Navigate().GoToUrl("http://www.google.com");

            Thread.Sleep(4444);

        }
