从JSON数组中创建嵌套JSON数组

使用 Json.NET 。

using System;
using System.Collections.Generic;
using Newtonsoft.Json;
public class Program
    public static void Main()
        string json = @"{
  ""access_token"": ""access token value here"" , ""user"": ""user_val""
        Access a = JsonConvert.DeserializeObject<Access>(json);
        var accessCollection = new AccessCollection
            Data = new List<Access> { a }
        json = JsonConvert.SerializeObject(accessCollection, Formatting.Indented);      
        Console.WriteLine(json);
public class Access
    [JsonProperty("access_token")]
    public string AccessToken
        get;
        set;
    [JsonProperty("user")]
    public string User
        get;
        set;
public class AccessCollection
    [JsonProperty("data")]
    public List<Access> Data
        get;
        set;
