How to check if an alert exists using WebDriver?

Question

I need to check the existence of Alert in WebDriver.

Sometimes it pops up an alert but sometimes it will not pop up. I need to check if the alert exists first, then I can accept or dismiss it or it will say: no alert found.

ExpectedConditions is obsolete, so:

        WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(15));
        wait.Until(SeleniumExtras.WaitHelpers.ExpectedConditions.AlertIsPresent());

C# Selenium 'ExpectedConditions is obsolete'
