不包含{“ d：”元素的JSON返回方法

Question

I currently have a WebGet method that returns JSON correctly with the nested { d: } element, is there a way to remove this?

Here is my Server Side Code and my class defining the JSON return:

[OperationContract, WebGet(ResponseFormat = WebMessageFormat.Json)]
    public List<OpenOrderHeader> GetOpenOrders()
    {
        return (from OH in SCMENT.CustomerOrders
                select new OpenOrderHeader()
                {
                    CustomerID = OH.CustomerId,
                    OrderID = OH.CustomerOrderID,
                    OrderUniqueNumber = OH.CustomerOrderUniqueNumber,
                    OrderDateCreated = OH.CustomerOrderDateCreated,
                    OrderDateUpdated = OH.CustomerOrderDateUpdated,
                    OrderLocalOnline = OH.CustomerOrderOnlineOrLocal,
                    BranchID = (int)OH.CustomerOrderLocalBranchID,
                    OrderCurrency = OH.CustomerOrderCurrency,
                    OrderConversionRate = OH.CustomerOrderCurrencyConversionRate,
                    OrderStatus = OH.CustomerOrderStatus
                }
                ).ToList();
    }

The Class:

  public class OpenOrderHeader
{
    public int CustomerID { get; set; }
    public int OrderID { get; set; }
    public int OrderUniqueNumber { get; set; }
    public int NumberOfProductsOnOrder { get; set; }
    public DateTime OrderDateCreated { get; set; }
    public DateTime OrderDateUpdated { get; set; }
    public string OrderLocalOnline { get; set; }
    public int BranchID { get; set; }
    public string PaymentMethod { get; set; }
    public int OrderStatus { get; set; }
    public string OrderCurrency { get; set; }
    public decimal OrderConversionRate { get; set; }
    public decimal SubTotalInclTax { get; set; }
    public decimal SubTotalExclTax { get; set; }
    public decimal DiscountInclTax { get; set; }
    public decimal DiscountExclTax { get; set; }
    public decimal ShippingInclTax { get; set; }
    public decimal ShippingExclTax { get; set; }
    public decimal PaymentFeeInclTax { get; set; }
    public decimal PaymentFeeExclTax { get; set; }


}

the JSON:

Answer 1

From what you've been saying, I think something like this should solve your problem:

JSONObject returnedObject = Your JSON data as returned from the server

JSONArray desiredArray = returnedObject.getJSONArray("d");

//retrieve the data and results from the JSONArray
for (int jsonCounter = 0; jsonCounter < desiredArray.length(); jsonCounter++) { 
    //Get the next object
    JSONObject nextobj = desiredArray.getJSONObject(jsonCounter);

    //Get the data
    item1= nextobj.getString("__type");
    item2= nextobj.getString("BranchID");
    etc......
}

And that's your basic structure to extract the data. From the code you've posted I'm not exactly sure where this would go, but it should be enough to help you on your way and extract your data. Also bear in mind that the above code was written in Android using the included JSON parser, so will require some alterations to make it work with a different library
