Asp.Net Web Api传递具有多个类属性的类

Question

我在上一个问题的上面的链接中提出了问题，并且评论中的更改已得到解决。

Properties of class parameter are always null in Asp.Net Web Api

但这次问题有点不同。方法参数是另一个具有多个类类型属性的类。

  [HttpPost]
    [EnableCors(origins: "*", headers: "*", methods: "*", exposedHeaders: "X-Custom-Header")]
    public IReportOutput InsuranceHandlingFiles([FromBody]InsuranceHandlingFilesInput insuranceHandlingFilesInput)
    {

    }

    public class InsuranceHandlingFilesInput
    {
    public CaseCountsInput CaseCountsInput { get; set; }
    public MioEurosInput MioEurosInput { get; set; }
    public SharesInput SharesInput { get; set; }
    }

以下列方式创建属于此类的Json对象后，我发送带有Post请求的帖子。但即使第一个属性正确填充，其他属性也为null。我该如何解决这个问题？

       function GetReportData() {

        var reportModel = {
            CaseCountsInput: {
