title: How to parse JSON received in MVC Controller
body: <p>I have a JSON file that is being sent to an MVC controller via a POST request from the client side. Since there isn't a direct way to store JSON in C#, I'm trying to create models to store the data. Here is the structure of the JSON:</p>
  
  <pre><code>{
      "SubscriptionsType1": {
          "Obj1": {
              "Value1": "3454234",
              "Value2": "345643564",
              "Value3": "665445",
              "Value4": "True"
          },
          "Obj2": {
              "Value1": "3454234",
              "Value2": "345643564",
              "Value3": "665445",
              "Value4": "True"
          },
          "Obj3": {
              "Value1": "3454234",
              "Value2": "345643564",
              "Value3": "665445",
              "Value4": "True"
          }
      },
  "SubscriptionsType2": {
                  "Obj1": {
                      "Value1": "3667635",
                      "Value2": "34563456",
                      "Value3": "234545",
                      "Value4": "False"
                  },
                  "Obj2": {
                      "Value1": "97865",
                      "Value2": "356356",
                      "Value3": "665757445",
                      "Value4": "True"
                  },
                  "Obj3": {
                      "Value1": "3454234",
                      "Value2": "345643564",
                      "Value3": "665445",
                      "Value4": "False"
                  }
              },
      //etc..
  
      }
  </code></pre>
  
  <p>The models are the following:</p>
  
  <pre><code>  public class RootObject {
          public IEnumerable&lt;SubscriptionObj&gt; Subscriptions { get; set; }
  }
  
  
  public class Subscriptions {
      IEnumerable&lt;SubscriptionObj&gt; objs;
  }
  
  
  public class SubscriptionObj
  {
      public Int64 Value1 {get;set;}
      public Int64 Value2 {get;set;}
      public Int64 Value3 {get;set;}
      public Boolean Value4 {get;set;}
  }
  </code></pre>
  
  <p>For some reason, if I create the model classes with this structure, the Root Object is still null after the it is passed the JSON object from the controller.
  However, when I explicitly create attributes to store each value of the JSON object, it works. Since the JSON object doesn't have a fixed number of elements, I need a way to dynamically store each attribute. <strong>How can this be done?</strong></p>
