.net mvc send json with mixed types from controller

Question

So I have this JsonResult:

[HttpPost]
public JsonResult getJsonInvoicesClient(int id_client)
{
    var a = db.invoices
        .Where(x => x.id_client == id_client)
        .ToList();
    return Json(a);
}

and in jquery I get a list of account objects. Now I need to add client data in json, so I get it from db with something like:

    var c = db.clients.FirstOrDefault(p => p.id == id_client);

But how can I add this client object to json ... so that in jquery I get a list or similar with only two elements: the client object and the list of invoice objects?

Answer 1

Use anonymous type:

var invoices = db.invoices
    .Where(x => x.id_client == id_client)
    .ToList();
var clinet = db.clients.FirstOrDefault(p => p.id == id_client);
return Json(new
{
    clinet,
    invoices
});
