title: Parse json string to find and element (key / value)
body: <p>I have following json in a file timezones.json:</p>
  
  <pre><code>  { "Atlantic/Canary": "GMT Standard Time", "Europe/Lisbon": "GMT Standard Time", 
  "Antarctica/Mawson": "West Asia Standard Time", "Etc/GMT+3": "SA Eastern Standard Time", 
  "Etc/GMT+2": "UTC-02", "Etc/GMT+1": "Cape Verde Standard Time", "Etc/GMT+7": "US Mountain 
  Standard Time", "Etc/GMT+6": "Central America Standard Time", "Etc/GMT+5": "SA Pacific 
  Standard Time", "Etc/GMT+4": "SA Western Standard Time", "Pacific/Wallis": "UTC+12", 
  "Europe/Skopje": "Central European Standard Time", "America/Coral_Harbour": "SA Pacific 
  Standard Time", "Asia/Dhaka": "Bangladesh Standard Time", "America/St_Lucia": "SA Western 
  Standard Time", "Asia/Kashgar": "China Standard Time", "America/Phoenix": "US Mountain 
  Standard Time", "Asia/Kuwait": "Arab Standard Time" }
  </code></pre>
  
  <p>I want to search for a particular key e.g. "Atlantic/Canary" from it and as a result want its value back i.e. "GMT Standard Time". </p>
  
  <p>How can I do this using Json.Net or any other efficient mean in C#?</p>
