Click all elements with same CssSelector or same XPath FindElements

Question

In Visual Studio writing the code for Selenium WebDriver, these two codes for the same button work fine only once.

Click the button By Css Selector:

driver.FindElement(By.CssSelector(".follow-text")).Click();

Click the button By XPath:

driver.FindElement(By.XPath("//button[@class='user-actions-follow-button js-follow-btn follow-button btn small small-follow-btn']")).Click();

Until this all correct...

But I want to click to all the buttons not to only the first, and because of the FindElements (in plural) get me error, how can I press click to all the buttons with that same code?

Using this get error:

List<IWebElement> textfields = new List<IWebElement>(); 
driver.FindElement(By.XPath("//button[@class='user-actions-follow-button js-follow-btn follow-button btn small small-follow-btn']")).Click();
driver.FindElement(By.XPath("//button[@class='user-actions-follow-button js-follow-btn follow-button btn small small-follow-btn'][3]")).Click();

See the capture:

You need to loop through FindElements result and call .Click() on each item :

var result = driver.FindElements(By.XPath("//button[@class='user-actions-follow-button js-follow-btn follow-button btn small small-follow-btn']"));
foreach (IWebElement element in result)
{
    element.Click();
}

FYI, you need to wrap the XPath in brackets to make your attempted code using XPath index works :

driver.FindElement(By.XPath("(//button[@class='user-actions-follow-button js-follow-btn follow-button btn small small-follow-btn'])[3]")).Click();
