如何使用json.net将c＃泛型列表转换为json？

这是一个例子：

using System;using System.Data;using Newtonsoft.Json.Linq;class Test{    static void Main()    {        DataTable table = new DataTable();        table.Columns.Add("userid");        table.Columns.Add("phone");        table.Columns.Add("email");        table.Rows.Add(new[] { "1", "9999999", "test@test.com" });        table.Rows.Add(new[] { "2", "1234567", "foo@test.com" });        table.Rows.Add(new[] { "3", "7654321", "bar@test.com" });        var query = from row in table.AsEnumerable()         select new {  userid = (string) row["userid"],  phone = (string) row["phone"],  email = (string) row["email"]          };        JObject o = JObject.FromObject(new        { Table = query        });        Console.WriteLine(o);    }}

文档： 使用Json.NET的LINQ to
JSON
