C＃以JSON序列化使用JSON.Net

Question

我有一个C＃列表看起来像这样：

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

我用下面的转换/序列化JSON（Newtonsoft.JSON）：

var json = JsonConvert.SerializeObject(reqUsers); 

与上面的代码我得到一个JSON字符串是这样的：

[{ 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" } ] 

但这里是我需要得到：因为我用的把手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来命名JSON数组？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);
