c# - ASP.NET Web API ModelState do not contains all parameters, validation do not work -

i'm using asp.net web api , have post method in controller:

[route("order/{siteid}/{orderid}")] public httpresponsemessage post(long siteid, long orderid, orderinformation orderinfo) { if (modelstate.isvalid) { ... } }

i have couple info annotations in orderinformation class (required etc.) unfortunately validation not work. because modelstate not contains key orderinfo. contains siteid , orderid.

so question why orderinfo parameter not included in modelstate. have not thought why works weird because utilize similar code on different places , works fine.

edit:

here model (orderinformation class):

public class torderinformation { [required] public string loyaltynumber; [required] public string specialinstructions; public bool sendemail; ... // few more string properties, no info annotations }

edit 2:

i'm sending complex type in body serialized json. tried signature of method:

[route("order/{siteid}/{orderid}")] public httpresponsemessage post(long siteid, long orderid, [frombody] orderinformation orderinfo)

uff found problem. there can't public fields in model, must properties.
