"反序列化嵌套对象数组的问题"

Question

Here are my models:

public class Order
{
    public IEnumerable<LineItem> LineItems { get; set; }
}

Answer 1

Try this using Newtonsoft.Json

using Newtonsoft.Json;
.....

 public List<Order> GetOrdersJson()
{
var result = _httpRequestService.CallApi(_url).Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject< List<Order>>(result.Result);
}

Answer 2

IEnumerable<T><\/code> is not a valid type for the serializer. It doesn't define any concrete implementation of a collection for the serializer to parse the JSON into. Use List<T><\/code> when deserializing JSON arrays.

Answer 3

 public List<Order> GetOrdersJson()
    {
        var result = _httpRequestService.CallApi(_url).Content.ReadAsStringAsync();
        return _httpRequestService.DeserializeApiResponseJson<Order>(result.Result);
    }
