I have the following POCO classes :

public class CountryResult : APIResult

 public CountryResult()
 
 Countries = new List<CountryDTO>();
 

 public List<CountryDTO> Countries
 
 get;
 set;
 


public class APIResult

 public Locale Locale
 
 get;
 set;
 

 [JsonProperty("authorised")]
 public bool Authorized
 
 get;
 set;
 

 public string UserMessage
 
 get;
 set;
 

 = "";

The json response should always to be consistent. The locale, authorised,userMessage are common in every payload response.

 "countries": ,
 "locale": 
 "localisationIdentifier": "en",
 "enabled": true,
 "language": "en",
 "country": "",
 "description": "English",
 "uuid": "37",
 "name": "English",
 "path": "/locales/en",
 "rightToLeft": false,
 "completeResponse": true,
 "scriptDirection": "ltr"
 ,
 "authorised": false,
 "userMessage": ""

I developed a CommonResponseMiddleware (Middlware component) in order to implement this requirement.

public class CommonResponseMiddleware

 private readonly RequestDelegate _next;
 private ICommonService _commonService;
 public CommonResponseMiddleware(RequestDelegate next, ICommonService commonService)
 
 _next = next;
 _commonService = commonService;
 

 public async Task Invoke(HttpContext context)
 
 var currentBody = context.Response.Body;
 using (var memoryStream = new MemoryStream())
 
 context.Response.Body = memoryStream;
 // Hit the web api and get the result
 await _next.Invoke(context);
 context.Response.Body = currentBody;
 memoryStream.Seek(0, SeekOrigin.Begin);
 var readToEnd = new StreamReader(memoryStream).ReadToEnd();
 var objResult = JsonConvert.DeserializeObject(readToEnd);
 
 

In the objResult I get the all the data for Entity: CountryResult but with all the properties of APIResult(locale, authorised,userMessage) still set to null.

How to setup the values of APIResult and return it as part of the complete payload?

Can anyone help me here to fix this issue by providing their guidance?
