How to check Newtonsoft.Json.Linq.JArray If null Or get length
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"}
]
json dynamic .net-core
