how do you Deserialize JSON in a list?

Hello, I have a question about JSON files and Deserialization. I'm using Unity and the MinJson library to Deserialize the information passed over by the Graph API with C#. Currently I can Deserialize arrays or individual items in a format like this.

"category_list": [{"id": "205950169432461","name": "Day Spa"}] "information" : "information that this holds"

what i'm having an issue with is when the Json is in a format such as this I believe they are called lists (please correct me if I'm wrong) :

"hours"{"day one": "time", "day_two": "time2", "day_three": "time3" }

What i'm doing to deserialize is this:

 //IResult being the Json information about the page passed by the Graph API
 public void DisplayBusinessInfo (IResult result)
 {
 String JsonString = result.RawResult;
 var PageInfo = Json.Deserialize(JsonString) as Dictionary<string, object>;
 //using the array example above
 List<object> categorylist = PageInfo["category_list"] as List<object>;
 }
 try
 {
 // this for loop breaks down the list that I stored categorylist into and returns the individual items within it
 for (int i = 0; i < categorylist.Count; i++)
 {
 Dictionary<string, object> messageData = categorylist[i] as Dictionary<string, object>;
 object resultData = messageData["name"];
 Debug.Log("JSON string : " + resultData.ToString());
 //returns the information : Day Spa
 }
 catch
 {
 Debug.Log("it is done");
 }
 //anything that is not an array goes directly into this if statement. Again i'll use the example I have provided above
 if (result.Error == null)
 {
 Information = "" + result.ResultDictionary["information"];
 //Returns : information that this holds
 }

What I don't understand about the list is how it's being classified in Deserialization. I have tried passing it through as an object and string but failed on both attempts. If you could help explain what Json information in {} is and provide a link or any help on deserializing it with the format I have currently, I would greatly appreciate it!
