Did you solve your problem, if not use this one, might help.

HttpResponseMessage response = client.PostAsJsonAsync("api/Account", LoginViewModel).Result;
f (response.IsSuccessStatusCode)
{
return RedirectToAction("Action", "Controller");
}
else
{
return null;
}

Nitin Bhardwaj · Answer

I have already used  FromBody.

Sachin Singh · Answer

okk leave restsharp and HttpClient just check by adding FromBody , i think that will work

Nitin Bhardwaj · Answer

Hi Sachin,
I need RestSharp for this code. I am getting error on this line "_client.Execute"

Sachin Singh · Answer

Test with request.AddJsonBody(model) and use [FromBody] in API

if (ModelState.IsValid)
{
model.UserName = appSettings.Value.UserName;
model.Password = appSettings.Value.Password;
model.ConCode = appSettings.Value.ConCode;
model.LoginIP = Response.HttpContext.Connection.RemoteIpAddress.ToString();
var request = new RestRequest("api/PostLogin", Method.POST) { RequestFormat = DataFormat.Json };
request.AddJsonBody(model);
var response = _client.Execute(request);
if (response.Data == null)
throw new Exception(response.ErrorMessage);
}
[HttpPost]
public void Post([FromBody] LoginViewModel model)
{
Console.WriteLine(message.val);
}

.Net core controller   using (var client = new HttpClient()) { client.BaseAddress = new Uri(appSettings.Value.APIBaseURL); LoginViewModel model = new LoginViewModel(); model.UserName = appSettings.Value.UserName; model.Password = appSettings.Value.Password; model.ConCode = appSettings.Value.ConCode; model.LoginIP = Response.HttpContext.Connection.RemoteIpAddress.ToString(); client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); var postTask = client.PostAsJsonAsync ("Account", model); /*var postTask = JsonConvert.DeserializeObject (stringData);*/ postTask.Wait(); }    API Controller   public IHttpActionResult PostLogin(LoginViewModel model) { if (!ModelState.IsValid) return BadRequest("Not a valid set of data."); //check credentials string passHash = model.Password; if (model.guestLogin != true) { var loginCommonObj = new LoginCommon(); passHash = loginCommonObj.EncryptData(model.Password); } }
