How to pass parameters to array class in webapi?

Question

I am new to asp.net mvc webapi.I am create one webapi service.In this service I am sending parameter as an array class.

Below is my service :

[AcceptVerbs("GET", "POST")]
public HttpResponseMessage addBusOrder(string UserUniqueID, int PlatFormID,
 string DeviceID, int RouteScheduleId,
 string JourneyDate, int FromCityid,
 int ToCityid, int TyPickUpID,
 Contactinfo Contactinfo, passenger[] pass)
{
 //done some work here
}
public class Contactinfo
{
 public string Name { get; set; }
 public string Email { get; set; }
 public string Phoneno { get; set; }
 public string mobile { get; set; }
}
public class passenger
{
 public string passengerName { get; set; }
 public string Age { get; set; }
 public string Fare { get; set; }
 public string Gender { get; set; }
 public string Seatno { get; set; }
 //public string Seattype { get; set; }
 // public bool Isacseat { get; set; }
}

Now how to pass passenger and contactinfo parameters to the above service.

Is there any changes in webapiconfig file? i want to pass passenger details like this:

passengername="pavan",
age="23",
Gender="M",

It will be much neater if you can create model of your parameter. To pass them from client side, you need to format them using one of data-interchange format. I prefer use JSON provided by Newtonsoft.Json library. Sending process is handled by HttpClient class provided by System.Net.Http namespace. Here is some sample:

Server Side

 //Only request with Post Verb that can contain body
 [AcceptVerbs("POST")]
 public HttpResponseMessage addBusOrder([FromBody]BusOrderModel)
 {
 //done some work here
 }
 //You may want to separate model into a class library so that server and client app can share the same model
 public class BusOrderModel
 {
 public string UserUniqueID { get; set; }
 public int PlatFormID { get; set; }
 public string DeviceID { get; set; }
 public int RouteScheduleId { get; set; }
 public string JourneyDate { get; set; }
 public int FromCityid { get; set; }
 public int ToCityid { get; set; }
 public int TyPickUpID { get; set; }
 public Contactinfo ContactInfo { get; set; }
 public passenger[] pass { get; set; }
 }

Client Side

 var busOrderModel = new BusOrderModel();
 var content = new StringContent(JsonConvert.SerializeObject(busOrderModel), Encoding.UTF8, "application/json");
 using (var handler = new HttpClientHandler())
 {
 using (HttpClient client = new HttpClient(handler, true))
 {
 client.BaseAddress = new Uri("yourdomain");
 client.DefaultRequestHeaders.Accept.Add(
 new MediaTypeWithQualityHeaderValue("application/json"));
 return await client.PostAsync(new Uri("yourdomain/controller/addBusOrder"), content);
 }
 }

Here's how you can do it:

First, since you are passing two objects as parameters we'll need a new class to hold them (because we can only bind one parameter to the request's content):

public class PassengersContact
{
 public Passenger[] Passengers { get; set; }
 public Contactinfo Contactinfo { get; set; }
}

and now for your controller (this is just a test controller):

[RoutePrefix("api")]
public class DefaultController : ApiController
{
 [HttpPost]
 // I prefer using attribute routing
 [Route("addBusOrder")]
 // FromUri means that the parameter comes from the uri of the request
 // FromBody means that the parameter comes from body of the request
 public IHttpActionResult addBusOrder([FromUri]string userUniqueId,
 [FromUri]int platFormId,
 [FromUri]string deviceId, [FromUri]int routeScheduleId,
 [FromUri]string journeyDate, [FromUri]int fromCityid,
 [FromUri]int toCityid, [FromUri]int tyPickUpId,
 [FromBody]PassengersContact passengersContact)
 {
 // Just for testing: I'm returning what was passed as a parameter
 return Ok(new
 {
 UserUniqueID = userUniqueId,
 PlatFormID = platFormId,
 RouteScheduleId = routeScheduleId,
 JourneyDate = journeyDate,
 FromCityid = fromCityid,
 ToCityid = toCityid,
 TyPickUpID = tyPickUpId,
 PassengersContact = passengersContact
 });
 }
}

Your request should look something like this:

POST http://<your server's URL>/api/addBusOrder?userUniqueId=a&platFormId=10&deviceId=b&routeScheduleId=11&journeyDate=c&fromCityid=12&toCityid=13&tyPickUpId=14
Content-Type: application/json
Content-Length: 110
{
 "passengers" : [{
 "passengerName" : "name",
 "age" : 52
 /* other fields go here */
 }
 ],
 "contactinfo" : {
 "name" : "contact info name",
 /* other fields go here */
 }
}

Notice the api/addBusOrder comes from concatenating the values of the RoutePrefix/Route attributes.

• Nasreddine: The passengers property is an array so you can pass as many passengers as you want in the Json array
