You can use [ScriptIgnore] attribute from System.Web.Script.Serialization on every property that you want to exclude from the object when serializing or deserializing:

  using System.Web.Script.Serialization;

  public class Product{
        public int ProductId { get; set; }
        public string ProductName { get; set; }

        [ScriptIgnore]
        public DataTable dt = new DataTable();
        [ScriptIgnore]
        public Category Category = new Category();
    }

In same class, create two functions returning boolean like this:

 public bool ShouldSerializedt()
 {
      return false;
 }

 public bool ShouldSerializeCategory()
 {
      return false;
 }

Function returns boolean. Its name is ShouldSerialize<<PropertyName>> and the return type of boolean controls serialization behavior

Best to use C# serialization mechanism. You may need separate class for the purpose of this "limited" serialization (in case you want these properties serialized in other scenarios) but that should do it. Take a look here: How to exclude property from Json Serialization
