我目前有一个 WebGet 方法，它使用嵌套的 { d: } 元素正确返回 JSON，有没有办法删除它？

这是我的服务器端代码和定义 JSON 返回的类：

[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();
    }

班上：

  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; }


}

从您所说的来看，我认为这样的事情应该可以解决您的问题：

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......
}

这就是您提取数据的基本结构。从您发布的代码中，我不确定这会去哪里，但它应该足以帮助您完成您的工作并提取您的数据。还要记住，上面的代码是使用包含的 JSON 解析器在 Android 中编写的，因此需要进行一些更改才能使其与不同的库一起使用
