C# 对象未从JSON体传递到方法中

我正在尝试运行我在MVCAPI中创建的一个方法，该方法要求通过JSON格式的主体将一个对象传递给它。据我所知，该方法或对象没有错误，但我发送的JSON实际上没有传递到该方法中，并且对象参数仍然为null

方法如下：

 // Consignment Search
[HttpPost]
[ResponseType(typeof(Legacy.JobTracking))]
[Route("api/search/")]
public IHttpActionResult SearchConsignment(ConsignmentSearch search)
{ 
    // Get the ID
    var UserId = 0;
    using (_PortalDb)
    {
        var User = _PortalDb.PortalUsers.FirstOrDefault(u => u.ServerUser == search.User);
        if (User != null) UserId = User.UserId;
    }
    List<Legacy.JobTracking> Consignments;
    if (!ModelState.IsValid) return BadRequest("Invalid Search");
    if (search.JobNo == null && search.CustRef == null && search.ConRef == null && search.DateFrom == null && search.DateTo == null) return BadRequest("No search filters");
    if (search.JobNo != null)
    {
        // Run Job number search and continue
        Consignments = Legacy.Exporter.GetJobByNo(search.JobNo, search.User, search.Account, UserId);
    }
    else if (search.ConRef != null)
    {
        // Run Con Ref Search and continue
        Consignments = Legacy.Exporter.GetJobByCon(search.ConRef, search.User, search.Account, UserId);
    }
    else if (search.CustRef != null)
    {
        // Run Customer Ref Search and continue
        Consignments = Legacy.Exporter.GetJobByRef(search.CustRef, search.User, search.Account, UserId);
    }
    else if (search.DateFrom != null && search.DateTo != null)
    {
        // Run Date Range Search and continue
        Consignments = Legacy.Exporter.GetJobsInDateRange(search.DateTo, search.DateFrom, search.User, search.Account, UserId);
    }
    else
    {
        return BadRequest("Invalid Date Search");
    }
    return Ok(Consignments);
}

以及正文中的JSON：

["consignmentSearch": {
  "dateFrom": "20150101",
  "dateTo": 20160101,
  "user": "LianeS",
  "account": "PORTAL"
}]

---

您在请求主体中传递的文本不是有效的JSON（当然也不代表您的模型）。适用于您的案例的有效JSON如下所示：

{
  "dateFrom": "20150101",
  "dateTo": 20160101,
  "user": "LianeS",
  "account": "PORTAL"
}

太好了！谢谢

{
  "dateFrom": "20150101",
  "dateTo": 20160101,
  "user": "LianeS",
  "account": "PORTAL"
}
