C# - Create object without null properties

I am new to C# and having difficulty with creating an object of a class using serialized json string. I have class defined with some member variable as follows:

class someClass{
   someclass(serializedJson) {
      JavascriptSerializer js = new JavascriptSerializer();
      var newObj = (someClass)(js.deserialize(serializedJson, typeof(serializedJson)));

   }
   // class has bunch of private and public member variables eg
   private string this._value;
   public string Price{
     get {
       return _price;
     }
     set {
       _price = somePrice;
     }
   }

}

Class is being called in some other file to create an object as:

var obj = new someClass(serializedJsonString);

serializedJsonString looks like:

{
  ... : ...,
  ... : ...
  // contains no key value pair for Price that I am trying to reference in constructor above. In other words, constructor should treat it as null.
}

Obviously, my obj is getting created with obj.Price being null.

Is there a way to:

1) Modifying getter/setter for Price to not have it has property for obj if its not coming in from serializedJson?

2) Remove the property "Price" from object because its null?

If you have value for Price field in deserialize object, then you must create public string Price { get; set; } and add suitable attribute, else if Price is depend on deserialized object then:

someclass(serializedJson)
{
    JavascriptSerializer js = new JavascriptSerializer();
    var newObj = (someClass)(js.deserialize(serializedJson, typeof(serializedJson)));
    Price = // ... some code
}
pblic string Price { get; }

You can't remove a property of an object dynamically, but you can use the getter to give the null value and return whatever you need, for example:

get
{
    return _price ?? string.Empty;
}
