JsonResult has no name, how do I access the values - asp.net

Question

I have a linq query in my controller that returns values from the database in JSON format. However The JSON object has no name so I tried a couple things but everything returns undefined.
My JSON object looks like:
Object {UserId: 4, UserName: "John", UserPassword: "Password"}
Controller
[HttpPost]
public JsonResult Index(string searchString, string searchPassword)
{
var user = (from u in db.Users where u.UserName.Equals(searchString) && u.UserPassword.Equals(searchPassword) select u).FirstOrDefault();
return Json(user);
}
Ajax
$('#test2').click(function(e) {
e.preventDefault();
var user = "John";
var userpass = "Password";
$.ajax({
url: "#Url.Action("Index", "Users")",
data: { "searchString": user, "searchPassword": userpass },
type: "post",
success: function (data) {
var results = [];
for (var i = 0; i < data.length; i++) {
results[data[i]["Key"]] = data[i]["Value"];
}
alert((result.UserName));
alert((result.UserPassword));
},
error: function (xhr, ajaxOptions, thrownError) {
console.log(xhr, ajaxOptions, thrownError);
}
})
})
The alerts come up with just undefined

Answer 1

You should be able to access the object by just using the properties from your C# object. So in your ajax success function, just use data.UserId or data.UserName

Answer 2

Do this in your ajax success
success: function (data) {
var results = [];
for (var i = 0; i < data.length; i++) {
result.push(data[i].UserId +" "+ data[i].UserName);
}
alert(result);
}
