将 JSON 反序列化为 .NET

Question

How to deserialize json of this kind into an object on C# ?

{
   "AND":[
      {
         "AND":[
            {
               "AND":[
                  {
                     "AND":[
                        {
                           "AND":[
                              {
                                 "AND":[
                                    {
                                       "OR":[
                                          {
                                             "OR":[
                                                "Title",
                                                "Login"
                                             ]
                                          },
                                          "LoginNote"
                                       ]
                                    },
                                    "BossTitle"

You can play with dynamic type, but I don't think it can help you.

class Program
    {
        static void Main(string[] args)
        {
            string unknownJson1 = "{\r\n  \"Id\": \"1e4495d3-4cd1-4bf2-9da6-4acee2f7a70e\",\r\n  \"Customers\": [\r\n    \"Alice\",\r\n    \"Bob\",\r\n    \"Eva\"\r\n  ]\r\n}";
            string unknownJson2 = "{\"AND\": [\"_ x041f__x0435__x0440__x0432__x04\", {\"AND\": [\"_ x0418__x0437__x0433__x043e__x04\", {\"AND\": [\"_ x041e__x043f__x0438__x0441__x04\", {\"AND\": [\"_ x041a__x043e__x0434_\", \"Title\"]}]}]}] } ";

            JsonSerializer serializer = new JsonSerializer();
            dynamic deserializedObject;

            using (var stringReader = new StringReader(unknownJson2))
            {
                using (var jsonReader = new JsonTextReader(stringReader))
                {
                    deserializedObject = serializer.Deserialize(jsonReader);
                }
            }

            Console.ReadKey(true);
        }
    }

quicktype's CLI supports JSON schema as an import format, which could help you represent the tree data structure you're parsing here. I'll look into why it wasn't detected automatically, but here's your model:

public class Tree
{
    [JsonProperty("AND")]
    public Leaf[] And { get; set; } // Could be null

    [JsonProperty("OR")]
    public Leaf[] Or { get; set; } // Could be null
}

public struct Leaf
{
    public string String; // Could be null
    public Top Tree; // Could be null
}

Your JSON should parse as this, although I haven't tested it.
