Double back slashes inserted on receiving JSON(HttpClient)

Question

I am new to programming and specifically new to .Net MVC(using .net core 2). I am having a controller method as below public  async Task  GetCountriesList( string  searchText)   {   HttpResponseMessage responseMessage;   string  responseContent =  string .Empty;   List  listCountries =  null ;   using  (var client = getHttpClient(WebClientContentType.JSON))   {   responseMessage = await client.GetAsync( new  Uri( string .Format( "{0}{1}" , _webApiUrl,  "/api/Country/GetCountryList" )));   if  (responseMessage.IsSuccessStatusCode)   {   responseContent = responseMessage.Content.ReadAsStringAsync().Result;   listCountries =(List )JsonConvert.DeserializeObject(responseContent,  typeof (List ));   if  (! string .IsNullOrEmpty(searchText))   {   listCountries = listCountries.Where(m => m.ShortName.ToLower().StartsWith(searchText.ToLower())).ToList();   }   }   else    {   return  Json(responseMessage.StatusCode);   }   }   return  Json(listCountries);   }   Here in "responseContent", i am getting extra slashes in my JSON   But in the API method, i am getting properly formatted JSON string My API method is [HttpGet] [Route( "api/Country/GetCountryList" )]   public  IActionResult GetCountryList()   {   ProcedureReturnType mediaType = GetMediaType();   try    {   CountryHelper countryHelper =  new  CountryHelper();   var result = countryHelper.GetCountries(mediaType);   return  Ok(result);   }   // end try    catch  (Exception ex)   {   return  BadRequest(ex.Message);   }  // end catch    }  // end method    Any way, i can solve this issue as i need the list of countries which i expect to get from the valid JSON in listCountries   For example if i write   var result = "\r"; return Ok(result);   Then the result sent is "\r", but on the receiving end at line   responseContent is having the value "\"\r\""
