将你想要的 JSON 粘贴到http://json2csharp.com你会得到这个：

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; }
}

这应该为您指明方向...

您也可以通过这种方式使用一些匿名类型：

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

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

等等等等
