使用 Newtonsoft.Json 时无法将数组的 Json 字符串数组反序列化为对象

Question

i am using Newtonsoft.Json and trying to deserialize an array of arrays Json string into C# object i created.

This is the json string -

[4615,4618,4619,4626,4615,4626,4631,4636,4637],[4615,4618,4619,4626,4615,4626,4631,4636,4637],[4615,4618,4619,4626,4615,4626,4631,4636,4637]

This is my object model -

  public class NumberMatrix
    {
        public List<int> NumberIDs { get; set; }

        public NumberMatrix()
        {
            this.NumberIDs = new List<int>();
        }
    }

This is how i try to convert -

var numbers = HttpContext.Current.Request.Params["Numbers"];
var numberIDsMatrix = JsonConvert.DeserializeObject<List<NumberMatrix>>(numbers);

i tried to deserialize the json in few ways, and got different errors. is it possible to deserialize this json string? how?

Answer 1

That isn't valid JSON, you need to surround it with [...] for example. You could do this:

var result = JsonConvert.DeserializeObject<List<List<int>>>($"[{numbers}]");
