I need to refresh WebElement in Selenium Webdriver without reload page.  

When i use a while, the text of the page element is constantly updated because it is a chat, but the loop carries only the same text.

```
while (driver.FindElements(By.ClassName("chat")).Count() > 0)
            {
                {
                    var element = driver.FindElement(By.ClassName("_chat")).Text;
                    Console.WriteLine(element);
                }
            }

```

I am using a C# project.  

Thanks!
