I have array coming in C# code of type dynamic. Before process it I need to check if 'answers' array has record so I tried number of attempt and I am not getting any result. I have tried if(array==null), Count(), Length, DefaultIfEmpty()



answerItem

{{

 "questionId": "9ca96ed8-ec33-c09b-a634-0e3e32245f99",

 "answers": ,

}}


above record is with null answers.



if record in answer array then it will be like 



"answer":[

    {"id":"333", "value":"my answer"}

  ]
