我怎么能Post json数据与嵌套数组列表使用webapi

Question

我想返回json格式的列表数据。我有两个poco类(订单，项目)使用这些poco类，我想将数据返回json格式

示例Json格式化我想要的返回使用webapi。

        {"order":{
          "LocationId":1,
           "Amount":"7.79",
          "OrderContactEmail":"[e-mail]",
          "OrderContactName":"test",
        "items":[{"Options":"y",
       "UnitCost":"7.79",
       "Quantity":"1","MenuItemId":"68"}],
       "DeviceIdentifier":"000000000000000",
        "ShipMethod":"PICK UP",
       "PickupDate":"2011-11-22 15:52:00",
       "OrderContactPhone":"123456"},
        "items":[{"Options":"y",
        "UnitCost":"7.79",
        "Quantity":"1","MenuItemId":"68"}],
        "DeviceIdentifier":"000000000000000",
         "ShipMethod":"PICK UP",
         "PickupDate":"2011-11-22 15:52:00",
         "OrderContactPhone":"123456"}}

将所需的JSON粘贴到http://json2csharp.com中，您将得到以下内容:

public class Item
{
    public string Options { get; set; }
    public string UnitCost { get; set; }
    public string Quantity { get; set; }
    public string MenuItemId { get; set; }
}
public class Order
{
    public int LocationId { get; set; }
    public string Amount { get; set; }
    public string OrderContactEmail { get; set; }
    public string OrderContactName { get; set; }
    public Item[] items { get; set; }
    public string DeviceIdentifier { get; set; }
    public string ShipMethod { get; set; }
    public string PickupDate { get; set; }
    public string OrderContactPhone { get; set; }
}
public class Item2
{
    public string Options { get; set; }
    public string UnitCost { get; set; }
    public string Quantity { get; set; }
    public string MenuItemId { get; set; }
}
public class RootObject
{
    public Order order { get; set; }
    public Item2[] items { get; set; }
    public string DeviceIdentifier { get; set; }
    public string ShipMethod { get; set; }
    public string PickupDate { get; set; }
    public string OrderContactPhone { get; set; }
}

这应该为你指明方向…

你也可以这样使用一些匿名类型:

var items = new Item[] {
    item1,
    item2
}
var json = new {
    order = new {
            LocationId = 1
            Items = items
        }
}

等。等。
