title: Forming Json Format String
body: <p>I am using this method to form <code>json</code> string and this is working fine. But i can't handle this if it contains more properties. Is there any other better method than this?</p>
  
  <pre><code>string.Format("{0}{1}longUrl{1}:{1}{2}{1}{3}", "{", "\"", longUrl,"}");
  </code></pre>
  
  <p>The output is</p>
  
  <pre><code>{"longUrl":"http://api.themoviedb.org/3/person/12835?api_key=2c50a994de5291887a4e062edd229a72"}
  </code></pre>
