body: <p>How can I get the real type that is in the string in c#? 
  For example, the method gets a string- <code>"123"</code> and it need to find it's real type- <code>int</code>, and convert this <code>string</code> to an <code>int</code> variable. Is there a simple way to do it? 
  Thanks in advance.</p>
