c# - 如何在c#中访问数据json.net数组

Question

我无法访问 json.net 反序列化的所有 json 数据。 我怎样才能访问它。当我在控制台中 WriteLine 时它​​为空。

帐户.cs

public class Account
{
public string Email { get; set; }
public bool Active { get; set; }
public DateTime CreatedDate { get; set; }
public IList<string> Roles { get; set; }
}

主类

 string json2 = @"{'Accounts' :[{
 'Email': '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="ed878c80889ead88958c809d8188c38e8280" rel="noreferrer noopener nofollow">[email protected]</a>',
  'Active': true,
  'CreatedDate': '2013-01-20T00:00:00Z',
  'Roles': [
    'User',
    'Admin']
},
{
 'Email': '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="a0cac1cdc5d3e0c5d8c1cdd0ccc58ec3cfcd92" rel="noreferrer noopener nofollow">[email protected]</a>',
  'Active': true,
  'CreatedDate': '2013-01-20T00:00:00Z',
  'Roles': [
    'Userz',
    'Adminz'
  ]
}]}";

    List<Account> account = new List<Account>();
    account.Add(JsonConvert.DeserializeObject<Account>(json2));


    // <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="553f3438302615302d34382539307b363a38" rel="noreferrer noopener nofollow">[email protected]</a>
    Console.Write(account[0].Email);

无法按照您想要的方式解析您拥有的 JSON 字符串。 Try this instead :

using System;
using System.Collections.Generic;
using Newtonsoft.Json;

public class Program
{
    public static void Main()
    {
        string json2 = @"[{
     'Email': '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="761c171b130536130e171b061a135815191b" rel="noreferrer noopener nofollow">[email protected]</a>',
      'Active': true,
      'CreatedDate': '2013-01-20T00:00:00Z',
      'Roles': [
        'User',
        'Admin']
    },
    {
     'Email': '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="254f4448405665405d44485549400b464a4817" rel="noreferrer noopener nofollow">[email protected]</a>',
      'Active': true,
      'CreatedDate': '2013-01-20T00:00:00Z',
      'Roles': [
        'Userz',
        'Adminz'
      ]
    }]";

    List<Account> account = new List<Account>();
    account.AddRange(JsonConvert.DeserializeObject<List<Account>>(json2));


    // <a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="3d575c50584e7d58455c504d5158135e5250" rel="noreferrer noopener nofollow">[email protected]</a>
    Console.Write(account[0].Email);
    }
}

public class Account
{
    public string Email { get; set; }
    public bool Active { get; set; }
    public DateTime CreatedDate { get; set; }
    public IList<string> Roles { get; set; }
}
