Add items to JSON using Json.net - json

Question

Using json.net, I've created a json string which is a serialized version of my data table, and am able to deserialize it back to a data table. Let's say my serialized text looks like this:
[{ 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" } ]
What I'd like to do is add some text to the beginning before the [, or to the end after the ], which would be included in the json text and not hinder the deserialization back to a data table.
I'm using the serialize command, sometimes with a class object as the second (optional) parameter of the serialization command, sometimes not. If I use the second argument, it results in a much more verbose json, which includes table and column definition information.
Either way, I want to possibly add a segment in the json text which will indicate success or failure of the lookup, but will not cause the deserialization to break.
Can anybody suggest a json.net method to do this?
Thanks...

public class Users
{
public string username { get; set; }
public string firstName { get; set; }
public string lastName { get; set; }
public string email { get; set; }
}
dynamic usercollectionWrapper = new
{
userList = new List<Users>
{
new Users()
{
username= "alan", firstName= "Alan", lastName= "Johnson", email= "alan#test.com"
},
new Users()
{
username= "allison", firstName= "Allison", lastName= "House", email= "al#test.com"
},
new Users()
{
username= "ryan", firstName= "Ryan", lastName= "Carson", email= "ryan#test.com"
}
}
};
var output = JsonConvert.SerializeObject(usercollectionWrapper);

Update:
public class Users
{
public string username { get; set; }
public string firstName { get; set; }
public string lastName { get; set; }
public string email { get; set; }
}
public class RootUsers
{
public string status { get; set; }
public List<Users> data { get; set; }
}
dynamic usercollectionWrapper = new
{
add = new RootUsers()
{
status = "success",
data = new List<Users>
{
new Users()
{
username= "alan", firstName= "Alan", lastName= "Johnson", email= "alan#test.com"
},
new Users()
