如何使用mvc3中的WEB API從json數組獲取數據數組？

Question

我已經在mvc3中使用Web Api創建了Web服務，在這裏我想從json獲取數據。 JSON結果這樣

{"order": { 
    "locationid": "1", 
    "deviceidentifier": "XXXXXXXXXXXXXXXXXXXXXXX", 
    "ordercontactname": "XXXXXXXXXXXXXXXXXXXXXXX", 
    "ordercontactphone": "XXXXXXXXXXXXXXXXXXXXXXX", 
    "ordercontactemail": "XXXXXXXXXXXXXXXXXXXXXXX", 
    "shipaddress1": "17 Brookfield", 
    "shipaddress2": "Suite 17", 
    "shipcity": "Irvine", 
    "shipstate": "CA", 
    "shipzipcode": "92604", 
    "shipphonenumber": "9493742114", 
    "shipemail": "Info@mail.com", 
    "shipmethod": "pickup", 
    "billingfirstname":"Tester", 
    "billinglastname":"test", 
    "billingmiddleinitial":"S", 
    "billingaddress":"field", 
    "billingcity":"Sample", 
    "billingstate":"SM", 
    "billingzipcode":"523201", 
    "billingphonenumber": "1234567891", 
    "billingemail": "", 
    "paytype":"creditcard", 
    "amount"="10.50", 
    "acctno"="123456789987", 
    "exproute"="0114", 
    "coupon"="X2323", 
    "notes"="", 
    "items": [ 
    {"itemid":"1","quantity":"1","price":"2.5","notes":"make it spicy"}, 
    {"itemid":"4","quantity":"2","price":"4.5","notes":""}, 
    {"itemid":"3","quantity":"1","price":"1.5","notes":""} 
    ] 
    }} 

爲了這個，我有創造波蘇類和我使用POCO類獲取訂單數據，但我不能讓項目陣列中的數據我怎麼能得到項目數據

Here is my code 

    public List<Message> PlaceOrder(PlaceOrder order) 
     { 
      // List<PlaceOrder> entities =   (List<PlaceOrder>)JavaScriptConvert.DeserializeObject(json, typeof(List<PlaceOrder>)); 
     int PayOrderID = 0; 
     List<Message> Result; 
     Result = new List<Message>(); 
     try 
     { 
      Order objOrder = new Order(); 
      PayHist objPayhis = new PayHist(); 
      objOrder.LocationId = order.LocationId; 
      objOrder.DeviceIdentifier = order.DeviceIdentifier; 
      objOrder.OrderContactName = order.OrderContactName; 
      objOrder.OrderContactPhone = order.OrderContactPhone; 
      objOrder.OrderContactEmail = order.OrderContactEmail; 
      string guid = Guid.NewGuid().ToString(); 
      objOrder.ShipMethod = order.ShipMethod; 
      objOrder.ShippingDate = Convert.ToDateTime(order.PickupDate); 
      objOrder.OrderGuid = guid; 
      entities.AddObject("Orders", objOrder); 
      entities.SaveChanges(); 
      int orderId = objOrder.OrderId; 
      PayOrderID = orderId; 
      objPayhis.OrderId = orderId; 
      objPayhis.PayType = order.ShipMethod; 
      objPayhis.Amount = float.Parse(order.Amount); 
      entities.AddObject("PayHists", objPayhis); 
      entities.SaveChanges(); 
      JavaScriptSerializer ser = new JavaScriptSerializer(); 
      // Order foo = ser.Deserialize<Order>(json); 

      Message objMessage = new Message(); 
      objMessage.Messagevalue = "Sucess"; 
      Result.Add(objMessage); 
      return Result; 


     } 

請幫我..

試試這個（你需要通過更換「=」的招牌來修復您的JSON「：」標誌」前）：

[WebInvoke(Method = "POST", UriTemplate = "")] 
public HttpResponseMessage Add(JsonValue json) { 
    JsonValue order = json["order"]; 
    JsonArray items = (JsonArray) order["items"]; 
    JsonValue item1 = items[0]; 
    var notes1 = item1["notes"]; 
    return new HttpResponseMessage(HttpStatusCode.OK); 
}
