json - 使用 JSON.Net 的 C# 到 JSON 序列化

Question

我有一个如下所示的 C# 列表:

var reqUsers = from user in users
    select new
    {
        username = user.username,
        firstName = user.firstName,
        lastName = user.lastName,
        email = user.email
    };

我使用以下内容将/序列化为 JSON (Newtonsoft.JSON):

var json = JsonConvert.SerializeObject(reqUsers);

通过上面的代码，我得到一个像这样的 json 字符串:

[{ username: "alan", firstName: "Alan", lastName: "Johnson", email: "alan@test.com" },
 { username: "allison", firstName: "Allison", lastName: "House", email: "al@test.com" },
 { username: "ryan", firstName: "Ryan", lastName: "Carson", email: "ryan@test.com" } ]

但是这是我需要得到的:因为我正在使用 Handlebars 模板 -

var testdata = {
  users: [
  { username: "alan", firstName: "Alan", lastName: "Johnson", email: "alan@test.com" },
  { username: "allison", firstName: "Allison", lastName: "House", email: "al@test.com" },
  { username: "ryan", firstName: "Ryan", lastName: "Carson", email: "ryan@test.com" } ]

如上如何使用Serializer来命名JSON数组？

用途:

var json = JsonConvert.SerializeObject(new { users = reqUsers });
