我遇到了将模型发送的数据绑定的问题。 我想要绑定的是OrderStatus，即使我通过它10它总是变成0。 我不知道为什么。我把这个部分加粗，以便在代码中更容易检测：
以JSON格式发送的数据：
{"CustomerOrderHeader":{"OrderNumber":"5",
"PartnerName":"BLI",
"Reference":"",
"ShippingDate":"10/152011",
"OrderStatusName":"Approved",
"CustomerOrderHeader.OrderStatus":"10",
"TotalAmount":"16.00",
"CustomerOrderHeader.CurrencyId":"0",
"CustomerOrderHeader.LanguageId":"0",
"DaLine1":"",
"DaLine2":"",
"DaCity":"",
"DaPostalCode":"",
"DaState":"",
"DaCountry":"",
"BaLine1":"",
"BaLine2":"",
"BaCity":"",
"BaPostalCode":"",
"BaState":"",
"BaCountry":"",
"Notes":""},
"CustomerOrderLines":[{"Id":214,"Num":10,"PartNumber":"dasdasd","Description":"dadadasd","OrderedQty":4,"UoM":"inteee","SalesPrice":null,"Amount":16,"LineStatus":10,"ConfirmedShippingDate":null,"ReservedQty":0,"DeliveredQty":0,"RemainingQty":4}]}
方法签名：
[HttpPost]
public JsonResult SaveOrUpdateOrderLines( CustomerOrderModel customerOrderModel )
和模型：
public class CustomerOrderModel
{
public CustomerOrderModel()
{
this.CustomerOrderLines = new List<CustomerOrderLineModel>();
this.CustomerOrderHeader = new CustomerOrderHeaderModel();

答案 0 :(得分：0)
乍一看，我看到的问题是您发送的是“OrderStatusName”，但该属性只有获取功能，而不是设置。
我没有检查其余的代码或测试过这个;但如果您没有OrderStatusName的SET，它将无效。
您可以发送OrderStates（它同时具有get; set;），或者将该集实现为OrderStatusName，我不建议这是不好的做法。
希望这有帮助， -covo
