这是我的班级：
FIRST API（POST）：
public class OrderMaster
{
public string DisplayorderId { get; set; }
public string ExtOrderId { get; set; }
public string ExtInfo { get; set; }
public int OrderStatusId { get; set; }
public bool IsDeliveryPickup { get; set; }
public string BranchCode { get; set; }
public DateTime DeliveryPickupDate { get; set; }
public decimal Price { get; set; }
public decimal ServiceCharge { get; set; }
public decimal ServiceChargePerc { get; set; }
public decimal CGST { get; set; }
public decimal SGST { get; set; }
public decimal IGST { get; set; }
public decimal DeliveryCharge { get; set; }
public decimal Discount { get; set; }
public decimal GiftWrapPrice { get; set; }
public string OfferCouponcode { get; set; }
public decimal OfferCouponDiscount { get; set; }
public string GiftCouponCode { get; set; }
public decimal GiftCouponPrice { get; set; }
public int WalletPrice { get; set; }
public string ShippingFullname { get; set; }
public string ShippingEmail { get; set; }
public string ShippingContactNo { get; set; }
public string ShippingAddress { get; set; }
public string ShippingCity { get; set; }
public string ShippingPincode { get; set; }
public string ShippingState { get; set; }
public string UserComment { get; set; }
public string CancelRemarks { get; set; }
public DateTime CancelDate { get; set; }
public DateTime OrderShippingDate { get; set; }
public DateTime OrderCompleteDate { get; set; }
public string CourierName { get; set; }
public string TrackingNo { get; set; }
public string PaymentGateway { get; set; }
public string PaymentType { get; set; }
public int PaymentStatus { get; set; }
public DateTime Createddate { get; set; }
public int TrnType { get; set; }
public int TrnCtrlNo { get; set; }
public List<GetOrderDtls> OrderDetails { get; set; }
}
public class GetOrderDtls
{
public int TrnCtrlNo { get; set; }
public int TrnType { get; set; }
public string ExtOrderId { get; set; }
public string Barcode { get; set; }
public string Product { get; set; }
public string Category { get; set; }
public string Brand { get; set; }
public int OrderQuantity { get; set; }
public decimal Price { get; set; }
public decimal CGST { get; set; }
public decimal SGST { get; set; }
public decimal IGST { get; set; }
public string OfferCode { get; set; }
public decimal OfferDiscount { get; set; }
public string IsGiftPack { get; set; }
public decimal ReturnQuantity { get; set; }
public decimal ReturnPrice { get; set; }
public string ReturnReason { get; set; }
public decimal DocEntDisc { get; set; }
public decimal DiscRate { get; set; }
}
但是，当我在下面的代码中收到一些数据时，它会在NULL对象列表中显示OrderDetails：
[System.Web.Http.HttpPost]
[ResponseType(typeof(OrderMaster))]
[System.Web.Http.Route("api/Order/OrderSave")]
public IHttpActionResult OrderIntegartion(List<OrderMaster> order)
{
/*var token = System.Web.HttpContext.Current.Request.Headers["Token"];
string webToken = WebConfigurationManager.AppSettings["token"];
*/
//if (token == webToken)
//{
string jsonString = Newtonsoft.Json.JsonConvert.SerializeObject(order);
}
来自此处的数据如下： 第二个API（GET）：
[HttpGet]
[ResponseType(typeof(List<Order>))]
[System.Web.Http.Route("api/Order/GetOrders")]
public async Task<IHttpActionResult> GetOrderData()
{
//List<Order> OrderList = new List<Order>();
//List<Orderdetail> OrderDList = new List<Orderdetail>();
//var list = db.GetSalesOrderHdr().ToList();
var list = db.GetSalesOrderHdr().ToList();
var data = new List<Order>();
foreach (var listdata in list)
{
var getorder = new Order() ;
//Order getorder = new Order() { Orderdetails = OrderDList };
getorder.DisplayorderId = listdata.OrderId;
getorder.ExtOrderId = listdata.DocNo;
getorder.ExtInfo = "";
getorder.OrderStatusId = listdata.Status;
getorder.BranchCode = listdata.VACompCode;
getorder.DeliveryPickupDate = listdata.DeliveryExptdDateTime;
getorder.Price = listdata.BTotDocValue;
getorder.ServiceCharge = 0;
getorder.ServiceChargePerc = 0;
getorder.CGST = Convert.ToDecimal(listdata.BTaxComp1);
getorder.SGST = Convert.ToDecimal(listdata.BTaxComp2);
getorder.IGST = Convert.ToDecimal(listdata.BTaxComp3);
getorder.DeliveryCharge = 0;
getorder.Discount = listdata.BTotDocDisc;
getorder.GiftWrapPrice = 0;
getorder.OfferCouponcode = "";
getorder.OfferCouponDiscount = 0;
getorder.GiftCouponCode = "";
getorder.GiftCouponPrice = 0;
getorder.WalletPrice = 0;
getorder.ShippingFullname = listdata.ShipToCustomerName;
getorder.ShippingEmail = listdata.ShipToEmail;
getorder.ShippingContactNo = listdata.PartyId;
getorder.ShippingAddress = listdata.ShipToFullAddr;
getorder.ShippingCity = listdata.ShipToCity;
getorder.ShippingPincode = "";
getorder.ShippingState = listdata.ShipToState;
getorder.UserComment = listdata.BDocRemarks;
getorder.CancelRemarks = listdata.RDocRemarks;
getorder.CancelDate = listdata.RDocDt;
getorder.OrderShippingDate = listdata.DeliveredDateTime;
getorder.OrderCompleteDate = Convert.ToDateTime(listdata.DocDt);
getorder.CourierName = "";
getorder.TrackingNo = "";
getorder.PaymentGateway = listdata.BPayModeTypeDesc;
getorder.PaymentType = listdata.BPayModeCode;
getorder.PaymentStatus = 0;
getorder.Createddate = Convert.ToDateTime(listdata.DocDt);
getorder.TrnType = listdata.TrnType;
getorder.TrnCtrlNo = listdata.TrnCtrlNo;
getorder.OrderDetails = db.GetSalesOrderHdrDtls(listdata.TrnType, listdata.TrnCtrlNo).ToList();
data.Add(getorder);
}
var Message = "";
using (HttpClient client = new HttpClient())
{
string stringData = JsonConvert.SerializeObject(data);
string UrlApi = ConfigurationManager.AppSettings["UrlApi"];
client.BaseAddress = new Uri(UrlApi);
MediaTypeWithQualityHeaderValue contentType = new MediaTypeWithQualityHeaderValue("application/json");
client.DefaultRequestHeaders.Accept.Add(contentType);
var contentData = new StringContent(stringData, System.Text.Encoding.UTF8, "application/json");
//HttpResponseMessage response = client.PostAsJsonAsync<List<Order>>("/api/Order/OrderSave", data).Result;
HttpResponseMessage response = client.PostAsync("/api/Order/OrderSave", contentData).Result;
Message = response.Content.ReadAsStringAsync().Result;
//Message = contentData.ToString();
}
return Ok(data);
}
课程如下：

{
public string DisplayorderId { get; set; }
public string ExtOrderId { get; set; }
public string ExtInfo { get; set; }

上述摘要：

因此，请查看上面的代码并提出更正建议。
答案 0 :(得分：0)
您的第一个POST接受List<OrderMaster>类型的参数，但您传递的是List<Order>。请注意，您需要从POST方法返回HttpResponseMessage，因为返回类型为IHttpActionResult，目前您的代码没有return语句。
您可以尝试使用以下代码
[System.Web.Http.HttpPost]
[ResponseType(typeof(Order))]
[System.Web.Http.Route("api/Order/OrderSave")]
public IHttpActionResult OrderIntegartion(List<Order> contentData)
{
/*var token = System.Web.HttpContext.Current.Request.Headers["Token"];
string webToken = WebConfigurationManager.AppSettings["token"];
*/
//if (token == webToken)
//{
string jsonString = Newtonsoft.Json.JsonConvert.SerializeObject(contentData);
return Ok<string> (jsonString);
}
此外，OrderMaster类的属性OrderDetails的类型为List<GetOrderDtls>
public List<GetOrderDtls> OrderDetails { get; set; }
但Order类有一个属性OrderDetails，其类型低于
public List<GetSalesOrderHdrDtls_Result> OrderDetails { get; set; }
因此，您在响应中将OrderDetails属性作为空数组。
