[c#] Parse json string to find and element (key / value)

I have following json in a file timezones.json:

  { "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" }

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".

How can I do this using Json.Net or any other efficient mean in C#?

You want to convert it to an object first and then access normally making sure to cast it.

JObject obj = JObject.Parse(json);
string name = (string) obj["Name"];
