为 JSON 序列化创建和存储对象？

Question

我正在根据获得的搜索结果创建对象。然后我尝试序列化对象以返回 JSON 格式的字符串。我正在尝试完成以下场景。我不想对任何 JSON 进行硬编码，我希望仅从对象序列化中输出 JSON。我不知道如何完成我正在寻找的东西。请注意，为简单起见，我在示例代码中硬编码了一些用户值。

我的代码：

using System;
using System.Collections.Generic;
using System.Web.Script.Serialization;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        getSearchResultsString();
    }

    public void getSearchResultsString()
    {
        string[] userList = { "user1", "user2", "user3" };

        var json = "";

        List<string> users = new List<string>();

        foreach (string user in userList)
        {

            string userName = "jsmith";

            string email = "jsmith@example.com";

            string createdDate = "3/20/2016";

            ADUser aduser = new ADUser(userName, email, createdDate);

            users.Add(new JavaScriptSerializer().Serialize(aduser));
        }
        json = String.Join(", ", users);
        Response.Write(json);
    }

    public class ADUser
    {
        public ADUser(string UserName, string Email, string CreatedDate)
        {
            userName = UserName;
            email = Email;
            createdDate = CreatedDate;
        }

        // Properties.
        public string userName { get; set; }
        public string email { get; set; }
        public string createdDate { get; set; }
    }
}

我目前的输出：

{"userName":"jsmith","email":"jsmith@example.com","createdDate":"3/20/2016"}, {"userName":"jsmith","email":"jsmith@example.com","createdDate":"3/20/2016"}, {"userName":"jsmith","email":"jsmith@example.com","createdDate":"3/20/2016"}

我想要的输出：

{
    "users": [{
        "userName": "jsmith",
        "email": "jsmith@example.com",
        "createdDate": "3/20/2016"
    }, {
        "userName": "jsmith",
        "email": "jsmith@example.com",
        "createdDate": "3/20/2016"
    }, {
        "userName": "jsmith",
        "email": "jsmith@example.com",
        "createdDate": "3/20/2016"
    }]
}

你可以尝试修改getSearchResultsString()作为打击

public static void getSearchResultsString()
    {
        string[] userList = { "user1", "user2", "user3" };

        var json = "";

        List<ADUser> users = new List<ADUser>();

        foreach (string user in userList)
        {

            string userName = "jsmith";

            string email = "jsmith@example.com";

            string createdDate = "3/20/2016";

            ADUser aduser = new ADUser(userName, email, createdDate);

            users.Add(aduser);
        }
        json = new JavaScriptSerializer().
            Serialize(new { users = users });
        Response.Write(json);
    }
