C# NewtonSoft JSON反序列化：System.StackOverflowException

JSON反序列化失败，出现异常System.StackOverflowException

我正在尝试反序列化以下实体。需要帮助，这是导致问题的原因

var workingJSONString = "{\"FBTOrLeaseYear\":{\"DateFrom\":\"2019-03-02T00:00:00\",\"DateTo\":\"2020-03-01T00:00:00\"},\"Registration\":\"155SQN\",\"NovatedLeaseFortnightBenefitGroups\":[],\"NovatedLeaseAnnualBenefitGroups\":[]}";

反序列化“Test.Entities.NovatedLeaseBenefitsBudgetSpentFBTYear”实体时

我收到一个异常“System.StackOverflowException”。有人能帮我解释一下为什么反序列化在这个JSON上失败了

请共享FBTORLEASEYARTH的结构这可能是一个递归问题。您的json中可能有递归定义的内容。@AnuViswan更新了FBTORLEASEYAR。请检查我无法重现该问题，未获取系统。StackOverflowException@EnricoMassone如果我将属性“NovatedLeaseFortnightBenefitGroups”或“NovatedLeaseAnualBenefitGroups”的数据添加到实体“NovatedLeaseBenefitsBudgetSpentfByYear”的列表中，则反序列化失败。无法在此处注意到任何递归数据。请让我知道，如果你注意到任何模式
