c#中给Json数组赋数组名

我有一个Json数组，看起来像这样:

[{"ticketAmount":5,"state":"Active"},{"ticketAmount":6,"state":"Closed"},{"ticketAmount":1,"state":"Resolve"}]

我想让它得到的是一个数组包含一个分配的变量然后Json，它应该是这样的(基本上给出数组名称):

"items":[{"ticketAmount":5,"state":"Active"},{"ticketAmount":6,"state":"Closed"},{"ticketAmount":1,"state":"Resolve"}]

我代码:

public class EntityUserClosed
{
        public int ticketAmount { get; set; }
        public string loggedDate { get; set; }
}
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void GetUserClosedTickets()
{
    var entites = new List<EntityUserClosed>();
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand("Select LoggedBy, count(ID) as ticketAmount from Tickets WHERE LoggedDate >=dateadd(day,datediff(day,0,GetDate())- 30,0) AND State = '3' group by LoggedBy"))
        {
            var ticketAmount = 0;
            var loggedBy = string.Empty;
            cmd.Connection = con;
            con.Open();
            var reader = cmd.ExecuteReader();
            if (reader.HasRows)
            {
                while (reader.Read())
                {
                     ticketAmount = (int)reader["ticketAmount"];
                     //Convert to JSON format
                     loggedBy = reader["LoggedBy"].ToString();
                     var entity = new EntityUserClosed
                            {
                                ticketAmount = ticketAmount,
                                loggedDate = loggedBy,
                            };
                     entites.Add(entity);
                 }
             }
             var json = serializer.Serialize(entites);
             this.Context.Response.ContentType = "application/json; charset=utf-8";
             var test = json.Replace("''", "");
             this.Context.Response.Write(test);
         }
     }
}

我尝试了一些解决方案，如:

var entity = new List<EntityUserClosed>()

但不确定如何工作

谢谢

var json = serializer.Serialize(new {items=entites} );
