How the int.TryParse actually works
<p>I've looked for int.TryParse method implementation, how it works actually, but I haven't found. I have to know, about a string, whether it's a numeric value, but I don't want to convert it at the this time.
So I need only the bool result from tryparse. So the questions are:</p>

<p>1, Is there any function wich can provide only the bool result, 
and </p>

<p>2, I'd like to know, how the tryparse actually works (is there a try catch inside or iterates through the characters of input string)?</p>

<p>Thanks for the answers!</p>
