I want to get result from website when I submit a form. There are serval ways that can go wrong. In simple scenario I want to return:

true - when form was submitted

false - when form wasn't submitted

null - when we don't know if form was submitted or not

I did that ugly try, because of NulLReferenceException (if form was filled correctly there is no summary element, and when form is filled uncorrectly there is no popup element).

How can I make this more elegant?

public bool? GetResult(TimeSpan timeout)
{
 var deadline = DateTime.Now.Add(timeout);
 do
 {
 // check if success
 try
 {
 var success = new WebDriverWait(Driver, TimeSpan.FromSeconds(5))
 .Until(ExpectedConditions.TextToBePresentInElement(Driver.FindElement(By.Id("summary")), "Success!"));
 if (success) return true;
 }
 catch (Exception ex)
 { }
 // check if not enough data
 try
 {
 var notEnoughData = new WebDriverWait(Driver, TimeSpan.FromSeconds(5))
 .Until(ExpectedConditions.TextToBePresentInElement(Driver.FindElement(By.Id("popup")), "Not enough data"));
 if (notEnoughData) return false;
 }
 catch (Exception ex)
 { }
 // check if too much data
 try
 {
 var tooMuchData = new WebDriverWait(Driver, TimeSpan.FromSeconds(5))
 .Until(ExpectedConditions.TextToBePresentInElement(Driver.FindElement(By.Id("popup")), "Too much data"));
 if (tooMuchData) return false;
 }
 catch (Exception ex)
 { }
 // check if empty data
 try
 {
 var tooMuchData = new WebDriverWait(Driver, TimeSpan.FromSeconds(5))
 .Until(ExpectedConditions.TextToBePresentInElement(Driver.FindElement(By.Id("popup")), "Empty data"));
 if (tooMuchData) return false;
 }
 catch (Exception ex)
 { }
 } while (DateTime.Now > deadline);
 return null;
}
