this is the view model

using System; 
using System.Collections.Generic;  
namespace WebApplication1.Models {

public class ReleaseNotesModel

public List<UserTypeModel> ReleaseUserTypeView { get; set; }        
 public List<ReleaseVersionModel> ReleaseVersionTypeView { get; set; }     
}   }  
and i am getting the response : 
 {     "ReleaseNoteTypeView": null,     "ReleaseItemTypeView": null,     "ReleaseUserTypeView": null,     "ReleaseVersionTypeView": null } 




don't know where is the mistake  

Answer 1

You can create a custom class matching this structure and return an instance of that class or a list of that class for the controller method.

Answer 2

Hi @Basit Nisar,

You can run the Web API project and search https://localhost:*****/api/ReleaseNote from your browser. Use the following code to view specific error messages in your browser.

catch (
Exception ex)            
{               
throw(ex);           
 }

First, there is no ReleaseItemTypeName parameter in ReleaseItemTypeView.

Remove AsNoTracking() method.

This is all the code:

        [Route("api/ReleaseNote")]
#pragma warning disable CS1998 // Async method lacks 'await' operators and will run synchronously         
        public async Task<IHttpActionResult> GetReleaseNotes()
#pragma warning restore CS1998 // Async method lacks 'await' operators and will run synchronously        
        {
          // ClaimsPrincipal principal = Request.GetRequestContext().Principal as ClaimsPrincipal;
           //Int32 LogedInID = Convert.ToInt32(principal.Claims.FirstOrDefault(t => t.Type == "LogedInID").Value);
            ReleaseNoteViewModel Releasenote = new ReleaseNoteViewModel();
            try
            {
                Releasenote.ReleaseVersionTypeView = db.ReleaseVersions.OrderBy(x => x.ReleaseVersionName).Select(x => new ReleaseVersionModel
                {
                    ReleaseVersionID = x.ReleaseVersionID,
                    ReleaseVersionName = x.ReleaseVersionName,
                    ReleaseUserTypeView = db.UserTypes.OrderBy(ka => ka.UserTypeName).Select(ka => new UserTypeModel
                    {
                        UserTypeID = ka.UserTypeID,
                        UserTypeName = ka.UserTypeName,
                        CreatedBy = ka.CreatedBy,
                        CreatedDate = ka.CreatedDate,
                        ModifiedBy = ka.ModifiedBy,
                        ModifiedDate = ka.ModifiedDate,
                        ReleaseItemTypeView = db.ReleaseItemTypes.OrderBy(t => t.ReleaseItemTypeNote).Select(t => new ReleaseItemModel
                        {
                            ReleaseItemTypeID = t.ReleaseItemTypeID,
                            ReleaseItemTypeNote = t.ReleaseItemTypeNote,
                            ReleaseNoteTypeView = db.ReleaseNotes.OrderBy(a => a.ReleaseNoteDescription).Select(a => new ReleaseNotesModel
                            {
                                ReleaseNoteID = a.ReleaseNoteID,
                                ReleaseNoteDescription = a.ReleaseNoteDescription,
                            }).ToList<ReleaseNotesModel>()
                        }).ToList<ReleaseItemModel>()
                    }).ToList<UserTypeModel>()
                }).ToList<ReleaseVersionModel>();
            }
            catch (Exception ex)
            {
               throw(ex);
            }
            return Ok(Releasenote);
        }
