粘贴您想JSON到http://json2csharp.com你会得到这样的：

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; } 
} 

这应该指向你的方向......

你也可以使用一些匿名类型是这样的：

var items = new Item[] { 
    item1, 
    item2 
} 

var json = new { 
    order = new { 
      LocationId = 1 
      Items = items 
     } 
} 

等等等
