Get Session ID for a Selenium RemoteWebDriver in C#

Question

I'm trying to get a session id for a test being run on the SauceLabs cloud, but I can't seem to access it.

I've tried the following approaches:

//Returns null
var sessionId = (string)((RemoteWebDriver)driver).Capabilities.GetCapability("webdriver.remote.sessionid");

//Will not compile
sessionId = ((RemoteWebDriver)driver).SessionId; //This is protected. 

The second approach is particularly confusing. It's a protected property, but if I can only access this from a derived class, then it's essentially useless for what I need.

Any help is appreciated.

In order for this to work, I had to create a class derived from RemoteWebDriver and then define a getter method. For example:

class  CustomeRemoteDriver : RemoteWebDriver
{

    public CustomeRemoteDriver(ICapabilities desiredCapabilities):base(desiredCapabilities)
    {
    }

    public CustomeRemoteDriver(ICommandExecutor commandExecutor, ICapabilities desiredCapabilities):base(commandExecutor, desiredCapabilities)
    {
    }

    public CustomeRemoteDriver(Uri remoteAddress, ICapabilities desiredCapabilities):base(remoteAddress, desiredCapabilities)
    {
    }

    public CustomeRemoteDriver(Uri remoteAddress, ICapabilities desiredCapabilities, TimeSpan commandTimeout):base(remoteAddress, desiredCapabilities, commandTimeout)
    {
    }

    public string GetSessionId()
    {
        return base.SessionId.ToString();
    }
}

Could also reach in using reflection.

            var sessionIdProperty = typeof(RemoteWebDriver).GetProperty("SessionId", BindingFlags.Instance | BindingFlags.NonPublic);
            if (sessionIdProperty != null)
            {
                SessionId sessionId = sessionIdProperty.GetValue(driver, null) as SessionId;
                if (sessionId == null)
                {
                    Trace.TraceWarning("Could not obtain SessionId.");
                }
                else
                {
                    Trace.TraceInformation("SessionId is " + sessionId.ToString());
                }
            }
