C＃以JSON序列化使用JSON.Net

Question

我有一個C＃列表看起來像這樣：

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

我用下面的轉換/序列化JSON（Newtonsoft.JSON）：

var json = JsonConvert.SerializeObject(reqUsers); 

與上面的代碼我得到一個JSON字符串是這樣的：

[{ 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" } ] 

但這裏是我需要得到：因爲我用的把手templatin g -

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" } ] 

如何使用Serializer來命名JSON數組？如上所述？

Answer 1

用途：

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

Answer 2

使用：

var json= new JavaScriptSerializer().Serialize(reqUsers);
