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<JsonResult> GetCountriesList(string searchText)
{
HttpResponseMessage responseMessage;
string responseContent = string.Empty;
List<Country> 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<Country>)JsonConvert.DeserializeObject(responseContent, typeof(List<Country>));
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\""
