Ooops! After a lot of googling came up with this fare solution. Made my day!!
Previously, I was trying this code:
//IWebElement body = webDriver.FindElement(By.TagName("body"));
//body.SendKeys(Keys.Control + 't');
But, it was neutral for me.
IWebDriver webDriver = new ChromeDriver();
webDriver.Manage().Window.Maximize();
webDriver.Navigate().GoToUrl(“www.google.co.in”);
//IWebElement body = webDriver.FindElement(By.TagName("body"));
//body.SendKeys(Keys.Control + 't');
IJavaScriptExecutor js = webDriver as IJavaScriptExecutor;
js.ExecuteScript("window.open();");
webDriver.SwitchTo().Window(webDriver.WindowHandles[1]);//Making 2nd Tab Active.
webDriver.Navigate().GoToUrl("https://yahoo.com/");
webDriver.Close();//Closing Active Tab (2nd
Tab)
webDriver.SwitchTo().Window(webDriver.WindowHandles[0]);// Making Tab Active.
