I want to serialize my json so it comes out like this

{
  "order": [
    {
      "ascending": true,
      "field": "string"
    }
  ],
  "groups": [
    {
      "ascending": true,
      "field": "string"
    }
  ],
  "start": 0,
  "limit": 0
}

I am trying to set the member properties and the values as well in one class called DiscoveryModel. I am confused on how to set the <list> values. This is what i have so far

public class DiscoveryModel
   {
          public static DiscoveryModel GetModelForUpdate()
       {
           return new DiscoveryModel
           {
              order = new List<Order> { ascending  = true, field = "string"}





           };
       }


       public List<Order> order { get; set; }

       public List<Group> groups { get; set; }

       public int start { get; set; }

       public int limit { get; set; }

       public class Order
       {

           public bool ascending { get; set; }

           public string field { get; set; }
       }

       public class Group
       {


           public bool ascending { get; set; }

           public string field { get; set; }
       }

}

What I have tried:

I am trying to add the payload and return to the method GetModelForUpdate.

So i am facing a problem assigning the values for the List. I am not sure how to do it. I have updated the question. I am not able to assign the member properties ascending and field

Here is the C# representation of your Json payload that can be used to de-serialize automatically with Newtonsoft Json or any other library.

I think you should keep your other logic separate from de-serialization

C#

public class Order
{
    public bool ascending { get; set; }
    public string field { get; set; }
}

public class Group
{
    public bool ascending { get; set; }
    public string field { get; set; }
}

public class DiscoveryModel
{
    public List<Order> order { get; set; }
    public List<Group> groups { get; set; }
    public int start { get; set; }
    public int limit { get; set; }
}

You can create a function to get new model initialized like this

C#

public DiscoveryModel GetModelForUpdate()
{
   return new DiscoveryModel()
   {
      order = new List<Order>() { new Order() { ascending = true, field = "string" } },
      groups = new List<Group>() { new Group() { ascending = true, field = "string" } },
      start = 1,
      limit = 10,
   };
}
