title: Difference between Object, Dynamic and Var
body: <p>I need to know the difference between these three keywords <code>Object</code> , <code>Dynamic</code> and <code>var</code> in C#.</p>
  
  <p>I have seen this <a href="http://www.codeproject.com/Articles/233553/Difference-between-Object-Dynamic-and-Var" rel="noreferrer">link</a> but i don't understand in which case i have to use each one.</p>
  
  <p>Can you explain for me, please, the difference between these keywords ? What are the utilities of each keyword?</p>
