title: What is System.Object ??? Reference type or Value Type
body: <p>As per my bookish knowledge I have learnt that System.object is reference type.
  I have tried following things to get understanding of the same:
  1. I had written following code in main method:</p>
  
  <pre><code>Object KC = 12;
  Get data(12); // method where I'm passing variable kj.
  //I'm performing some manipulation in method for kj &amp; value sets as 15. 
  Console.WriteLine(kj); // Expected output is 15 . 
  </code></pre>
  
  <p>Considering kj is object and reference type. But I'm getting output as 12.......</p>
  
  <p>Can someone explain me the above situation.</p>
