jquery - C# web-api post to function with two parameters -

i trying post 2 parameters following function dont manage reach function:

public void setshopsubcategories([frombody]string userid, int []subcategories ) {  } 

this how post:

var subcategories = [ 1, 2, 3, 4, 5]; var userid = "123";              $.ajax({                 type: "post",                 url: "/category/setshopsubcategories/",                 contenttype: 'application/json; charset=utf-8',                 data: json.stringify(userid, subcategories),                 success: function () {                     alert("ok");                 },                 error: function () {                     alert("error");                 } 

when post 1 parameter goes , can reach function:

public void setshopsubcategories([frombody]string userid ) {  }  var userid = "123";          $.ajax({             type: "post",             url: "/category/setshopsubcategories/",             contenttype: 'application/json; charset=utf-8',             data: json.stringify(userid, subcategories),             success: function () {                 alert("ok");             },             error: function () {                 alert("error");             } 

this 1 goes well:

public void setshopsubcategories( int []subcategories ) {  }  var subcategories = [ 1, 2, 3, 4, 5];               $.ajax({                 type: "post",                 url: "/category/setshopsubcategories/",                 contenttype: 'application/json; charset=utf-8',                 data: json.stringify(subcategories),                 success: function () {                     alert("ok");                 },                 error: function () {                     alert("error");                 } 

my routconfig:

 routes.ignoreroute("{resource}.axd/{*pathinfo}");               globalconfiguration.configuration.routes.maphttproute(                 name: "setcategories",                 routetemplate: "{controller}/{action}"             );               routes.maproute(                 name: "default",                 url: "{controller}/{action}/{id}",                 defaults: new { controller = "home", action = "index", id = urlparameter.optional }             ); 

model

public class mymodel     {         public string userid { get; set; }                 public int[] subcategories { get; set; }     } 

controller action

[httppost]         public void setshopsubcategories([frombody]mymodel model)         {          } 

ajax call:

var subcategories = [1, 2, 3, 4, 5]; var userid = "123" $.ajax({     type: "post",     url: "/api/values",     contenttype: "application/json; charset=utf-8",       data: json.stringify({ userid: userid, subcategories: subcategories }),     success: function () {         alert("ok");     },     error: function () {         alert("error");     } });

you find multiple parameter not allowed or problematic due type of stream.
