Json序列化，键既是字符串又是对象

Question

我正在努力进行JSON序列化，其中JSON blob有一个名为 answerValue 的键，它既是字符串又是对象，我真的不知道如何使用该键。 ， 我试图创建一个名为AnswerValues的新类，问题是它同时返回AnswersValue和AnswerValue，并且正如您在blob中看到的那样，它只应返回其中之一。 关于如何构造类以使其正常工作的任何提示都应该？

  var jsonBody = new Root()


      {
            questions = new[]
               {
                   new Question() {
                   questionId = "3.01",
                   question ="Ipsum Lorem",
                       answers = new []
                        {
                            new Answer(){
                                answerChoiceId = "b2b-3.01",
                                    answerValue = new AnswerValue(){

                               }
