Liste <Model> kommt als Null

Question

neu zu ASP.net zurück und haben eine Frage mit einem Modell, das mehrere Variablen des gleichen Typs hat.

Ich habe Bestellmodell, das 0 bis n Detailmodelle haben kann. Wenn ich die HTTP-Anfrage POST, bekomme ich alle Informationen für die Bestellung, außer das Detail-Modell kommt immer als Null zurück. Oder genauer gesagt ist die ".count" -Methode auf der Liste 0.

Wie bekomme ich es, um alle Details für mein Modell zu veröffentlichen?

Bestellen Modell:

public struct shipTo 
{ 
public string id; 
public string Line1; 
public int PostalCode; 
public string City; 
public string State; 
public string CountryCode; 
} 

namespace USS_EDIv2.Models 
{ 


public class Order 
{ 
    public Int64 SalesOrderNumber { get; set; } 
    public Int64 PurchaseOrderNumber { get; set; } 
    public Int64 BranchPlant { get; set; } 
    public shipTo ShipTo; 
    public Int64 Quantity { get; set; } 
    public string UOM { get; set; } 
    public List<Detail> Detail = new List<Detail>(); 
} 



} 

Details Modell:

namespace USS_EDIv2.Models 
{ 

public class Detail 
{ 
    public string LineNumber; 
    public string GradeItem; 
    public string Quantity; 
    public string UOM; 
    public string RequestDate; 
    public string Status; 

    public Detail() 
    { 

     LineNumber = "1"; 
     GradeItem = "1"; 
     Quantity = "1"; 
     UOM = "1"; 
     RequestDate = "1"; 
     Status = "1"; 
    } 

} 
} 

Repository Klasse:

namespace USS_EDIv2.Services 
{ 

public class SalesRepository 
{ 
    public DateTime currentTime = System.DateTime.Now; 
    private const string CacheKey = "4041tmtTEST1337"; 
    public string xml; 
    public int i; 
    public Order[] GetAllSales() 
    { 
     var ctx = HttpContext.Current; 

     if (ctx != null) 
     { 
      return (Order[])ctx.Cache[CacheKey]; 
     } 

     return new Order[] 
    { 
     new Order 
     { 

     } 
    }; 

    } 

    public SalesRepository() 
    { 
     var ctx = HttpContext.Current; 

     if (ctx != null) 
     { 
      if (ctx.Cache[CacheKey] == null) 
      { 
       var sales = new Order[] 
        { 

        }; 

       { 
       }; 
       ctx.Cache[CacheKey] = sales; 
       //ctx.Cache.Remove("4041tmtTEST1337"); 
      } 
     } 
    } 

    public bool SaveSale(Order sales) 
    { 
     var ctx = HttpContext.Current; 

     if (ctx != null) 
     { 
      try 
      { 

       var currentData = ((Order[])ctx.Cache[CacheKey]).ToList(); 


       currentData.Add(sales); 

       ctx.Cache[CacheKey] = currentData.ToArray(); 

       return true; 
      } 
      catch (Exception ex) 
      { 
       Console.WriteLine(ex.ToString()); 
       return false; 
      } 
     } 

     return false; 
    } 

} 
} 

Und mein Controller:

namespace USS_EDIv2.Controllers 
{ 
public class NewOrderController : ApiController 
{ 
    public DateTime currentTime = System.DateTime.Now; 
    private SalesRepository salesRepository; 
    public int i; 

    public NewOrderController() 
    { 
     this.salesRepository = new SalesRepository(); 
    } 

    public Order[] Get() 
    { 
     return salesRepository.GetAllSales(); 
    } 


    public HttpResponseMessage Post(Order sale) 
    { 
     var ctx = HttpContext.Current; 

     this.salesRepository.SaveSale(sale); 

     var response = Request.CreateResponse<Order> (System.Net.HttpStatusCode.Created, sale); 

     return response; 
    } 



} 

} 

Dies ist die XML-Daten angefordert werden:

<Order> 

<SalesOrderNumber>1294288</SalesOrderNumber> 

<PurchaseOrderNumber>81896</PurchaseOrderNumber> 

<BranchPlant>9701</BranchPlant> 

<ShipTo id="string"> 

<Line1>RAIL TRACK #769 SPOT 00</Line1> 

<PostalCode>79765</PostalCode> 

<City>MIDLAND COUNTY</City> 

<State>TX</State> 

<CountryCode>US</CountryCode> 

</ShipTo> 

<Quantity>75</Quantity> 

<UOM>TN</UOM> 



<Detail created="2015-12-14T13:59:57.84" action="Create"> 

<LineNumber>1.0</LineNumber> 

<GradeItem>97010B00000</GradeItem> 

<Quantity>25.000</Quantity> 

<UOM>TN</UOM> 

<RequestDate>2015-07-11</RequestDate>

<UOM>TN</UOM> 

<RequestDate>2015-07-11</RequestDate> 

<Status>Open</Status> 

</Detail> 

</Order> 

Und das ist meine aktuelle Antwort:

<ArrayOfOrder xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
<Order> 
<ShipTo> 
<Line1>RAIL TRACK #769 SPOT 00</Line1> 
<PostalCode>79765</PostalCode> 
<City>MIDLAND COUNTY</City> 
<State>TX</State> 
<CountryCode>US</CountryCode> 
</ShipTo>

Ich habe auch keine Kontrolle über das Format der eingehenden XML-Daten zu ändern. Jeder Zeiger in die richtige Richtung wäre bitte hilfreich.

Answer 1

Okay,

So löste ich dies durch die XML-Daten auf meine Zwischenablage zu kopieren, eine neue Klasse zu erstellen und dann gehen Sie zu Bearbeiten -> Inhalte einfügen -> einfügen von XML als Klassen

und es kam mit dieser:

Nur für den Fall, dass jemand über dieses Problem stolpert. Was mir stundenlange Kopfschmerzen bereitete, brauchte 3 Klicks, um es zu lösen ... Danke an alle für deine Antworten.
