c# - How to validate GET url parameters through ModelState with data annotation -


i have web api project... respect rest principles, should have method , post method... have search, think matches method, because after search obtain result , show in page... if not find must create object... action post...

now have problem... must validate filters of search, because filters tax code , alpha-numeric code (6 chars)... have done client side validation. should server side validation.

untill now, have used data annotation validate request, get... method has signature:

[httpget] public ihttpactionresult getactivationstatus(string taxcode, string requestcode) {     if (modelstate.isvalid)     {          ...     } }

but how can validate modelstate data annotation?

thank you

create own model...

public class yourmodel  {     [//dataannotation ...]     public string taxcode { get; set; }     [//dataannotation ...]     public string requestcode { get; set; } }

and change signature of server side controller:

[httpget] public ihttpactionresult getactivationstatus([fromuri] yourmodel yourmodel) {     if (modelstate.isvalid)     {          ...     } }

if client side code worked don't have change it... please, note properties of model same of parameter passing (string taxcode, string requestcode)... , case sensitive...

edit: mean can call controller in way:

http://localhost/api/values/?taxcode=xxxx&requestcode=yyyy
