How to remove null value in json string

Hi I'm using the below class

Public List<string> name;
Public List<string> midname;

Once I serialize it I'm getting the following output like

 {"name":[hari],"midname":null}

But I want my answer to be like this

{"name":[hari]}

It shouldn't display the class attribute that has null value and I'm using c# .net framework.

 

 

If you are using Json.Net then You can try this by Decorating your property like this [JsonProperty(NullValueHandling = NullValueHandling.Ignore)] public List<string> name { get; set; }
