Question

How do we return generic response in WebAPI2 by using below example. here instead of string i want to return as a generic object.

    public class CustomActionResult : IHttpActionResult
    {
        HttpStatusCode _httpStatusCode;
        string _value;
        HttpRequestMessage _request;

        public CustomActionResult(HttpStatusCode httpStatusCode, string value, HttpRequestMessage request)
        {
            _httpStatusCode = httpStatusCode;
            _value = value;
            _request = request;
        }
        public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
        {
            var response = new HttpResponseMessage()
            {
                StatusCode = _httpStatusCode,
                RequestMessage = _request,
                Content = new StringContent(_value),
                
            };
            return Task.FromResult(response);
        }
    }

    public class CustomActionResult : IHttpActionResult<o:p></o:p>

    {<o:p></o:p>

        HttpStatusCode _httpStatusCode;<o:p></o:p>

        string _value;<o:p></o:p>

        HttpRequestMessage _request;<o:p></o:p>

<o:p> </o:p>

        public CustomActionResult(HttpStatusCode httpStatusCode, string value, HttpRequestMessage request)<o:p></o:p>

        {<o:p></o:p>

            _httpStatusCode = httpStatusCode;<o:p></o:p>

            _value = value;<o:p></o:p>

            _request = request;<o:p></o:p>

        }<o:p></o:p>

        public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)<o:p></o:p>

        {<o:p></o:p>

            var response = new HttpResponseMessage()<o:p></o:p>

            {<o:p></o:p>

                StatusCode = _httpStatusCode,<o:p></o:p>

                RequestMessage = _request,<o:p></o:p>

                Content = new StringContent(_value)<o:p></o:p>

                <o:p></o:p>

            };<o:p></o:p>

            return Task.FromResult(response);<o:p></o:p>

        }<o:p></o:p>

    }<o:p></o:p>

Hello pathipathi,

You can try something like this.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Net.Http.Formatting;
using System.Threading;
using System.Threading.Tasks;
using System.Web;
using System.Web.Http;

namespace _2052052.Results
{
  public class CustomActionResult<T> : IHttpActionResult
  {
    HttpStatusCode _httpStatusCode;

    T _value;

    HttpRequestMessage _request;

    public CustomActionResult(HttpStatusCode httpStatusCode, T value, HttpRequestMessage request)
    {
      _httpStatusCode = httpStatusCode;
      _value = value;
      _request = request;
    }
    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
      var response = new HttpResponseMessage()
      {
        StatusCode = _httpStatusCode,
        RequestMessage = _request,
        Content = new ObjectContent(typeof(T), _value, new JsonMediaTypeFormatter())
      };
      return Task.FromResult(response);
    }

  }
}

When creating the new object of customactionresult

new CustomActionResult<object>(httpStatusCode,object,request); 
//<..> you can pass desired return type to content in brackets

Hope this helps.
