Question

我正在尝试将来自Web服务的JSON响应放入一个对象，我可以将其传递给我的视图并显示结果。我似乎有一些问题反序列化JSON。这是错误。

无法将当前JSON数组（例如[1,2,3]）反序列化为类型＆＃39; Project.Models.Order＆＃39;因为类型需要JSON对象（例如{＆＃34; name＆＃34;：＆＃34; value＆＃34;}）才能正确反序列化。要修复此错误，请将JSON更改为JSON对象（例如{＆＃34; name＆＃34;：＆＃34; value＆＃34;}）或将反序列化类型更改为实现集合接口的数组或类型（例如ICollection，IList）就像可以从JSON数组反序列化的List。 JsonArrayAttribute也可以添加到类型中以强制它从JSON数组反序列化。路径＆＃39;＆＃39;，第1行，第1位。

我的控制器代码如下。

string url = @"URL of webservice here";

var returnValue = new WebClient().DownloadString(url);

var obj = JsonConvert.DeserializeObject<Order>(returnValue);

return View(obj);

以下是我的观点。

@model Project.Models.Order

@foreach (var order in Model.sWorkOrderNumber)
{
    @Model.sWorkOrderNumber
}

这是返回的JSON。

[{"ShipmentTrackingNUmbers":[{"sTrackingNumber":"Redacted"}],"dtDateShipped":"5/12/2017 12:00:00 AM","dSPRatedWeight":"41.0000","nMBTotalBoxes":"1","sShipToAddressLine2":"Redacted","sShipToCountry":"U.S.A.","sShipToZip":"Redacted","sShipToState":"Redacted","sShipToCity":"Redacted","sShipToAddressLine1":"Redacted","sShipToName":"Redacted","sServiceLevel":"GND","sInvoiceNumber":"","dtInvoiceDate":"","mInvoiceAmount":"","dtDateReceived":"5/8/2017 3:16:25 PM","sStudioCategory2":"","sStudioCategory1":"","sOrderSource":"Redacted","sCustomerComments":"Redacted","sCustomerOrderName":"Redacted","sWorkOrderNumber":"Redacted","sCustomerNumber":"Redacted"},{"ShipmentTrackingNUmbers":[{"sTrackingNumber":"Redacted"}],"dtDateShipped":"5/10/2016 12:00:00 AM","dSPRatedWeight":"3.0000","nMBTotalBoxes":"1","sShipToAddressLine2":"","sShipToCountry":"U.S.A.","sShipToZip":"Redacted","sShipToState":"Redacted","sShipToCity":"Redacted","sShipToAddressLine1":"Redacted","sShipToName":"Redacted","sServiceLevel":"GND","sInvoiceNumber":"","dtInvoiceDate":"","mInvoiceAmount":"","dtDateReceived":"5/2/2016 7:18:41 AM","sStudioCategory2":"","sStudioCategory1":"","sOrderSource":"Redacted","sCustomerComments":"Redacted","sCustomerOrderName":"Redacted","sWorkOrderNumber":"Redacted","sCustomerNumber":"Redacted"}]

编辑：添加订单型号代码

namespace Project.Models
{
public class Order
{
    public string ShipmentTrackingNUmbers
    {
        get;
        set;
    }
    public string dtDateShipped
    {
        get;
        set;

        set;
    }
    public string nMBTotalBoxes
    {
        get;
        set;
    }
    public string sShipToAddressLine2
    {
        get;
        set;
    }
    public string sShipToCountry

        get;

        set;
    }
    public string sCustomerComments
    {
        get;
        set;
    }
    public string sCustomerOrderName
    {
        get;
        set;
    }
    public string sWorkOrderNumber
    {
        get;
        set;
    }
    public string sCustomerNumber
    {
        get;
        set;

}
}

提前感谢您的帮助。我已经尝试了各种方法来正确格式化，无法使其工作。任何指导都会很棒。

你的模型看起来应该是这样的。请注意，ShipmentTrackingNUmbers是List

class Shipment
{
    public List<ShipmentTrackingNUmbers> ShipmentTrackingNUmbers { get; set; }
    public string dtDateShipped { get; set; }
    public string dSPRatedWeight { get; set; }
    public string nMBTotalBoxes { get; set; }
    public string sShipToAddressLine2 { get; set; }
}

public class ShipmentTrackingNUmbers
{
    public string sTrackingNumber { get; set; }
}

现在，您可以将returnValue反序列化为货件清单

List<Shipment> shipments = JsonConvert.DeserializeObject<List<Shipment>>(returnValue);

无法反序列化当前的JSON数组问题
