below is a sample action which is returning HttpResponseMessage
and if any error occur then this way web api action returning error message and status code to client side return Request.CreateErrorResponse(HttpStatusCode.NotFound, message);
.
[HttpGet, Route("GetAll")]
public HttpResponseMessage GetAllCustomers()
{
IEnumerable<Customer> customers = repository.GetAll();
if (customers == null)
{
var message = string.Format("No customers found");
return Request.CreateErrorResponse(HttpStatusCode.NotFound, message);
}
else
{
return Request.CreateResponse(HttpStatusCode.OK, customers);
}
}
when i am invoking action by http client then i am not getting message in ReasonPhrase
property. just tell me what is the right way to read message at client side which is passing like this way return Request.CreateResponse(HttpStatusCode.OK, customers);
private async void btnFind_Click(object sender, EventArgs e)
{
var fullAddress = baseAddress + "api/customer/GetByID/"+txtFind.Text;
Customer _Customer = null;
using (var client = new HttpClient())
{
using (var response = client.GetAsync(fullAddress).Result)
{
if (response.IsSuccessStatusCode)
{
var customerJsonString = await response.Content.ReadAsStringAsync();
_Customer = JsonConvert.DeserializeObject<Customer>(customerJsonString);
}
else
{
Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
}
}
}
if (_Customer != null)
{
var _CustList = new List<Customer> { _Customer };
dgCustomers.DataSource = _CustList;
}
}
response.ReasonPhrase
not holding the message which i am passing from action. so may be i am not doing things to read message. please tell me what to change in my code to read the message. thanks

i have the job this way.
private async void btnFind_Click(object sender, EventArgs e)
{
var fullAddress = baseAddress + "api/customer/GetByID/"+txtFind.Text;
Customer _Customer = null;
try
{
using (var client = new HttpClient())
{
using (var response = client.GetAsync(fullAddress).Result)
{
if (response.IsSuccessStatusCode)
{
var customerJsonString = await response.Content.ReadAsStringAsync();
_Customer = JsonConvert.DeserializeObject<Customer>(customerJsonString);
}
else
{
//Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
var ErrMsg = JsonConvert.DeserializeObject<dynamic>(response.Content.ReadAsStringAsync().Result);
MessageBox.Show(ErrMsg.Message);
}
}
}
if (_Customer != null)
{
var _CustList = new List<Customer> { _Customer };
dgCustomers.DataSource = _CustList;
}
}
catch (HttpRequestException ex)
{
// catch any exception here
}
}
read error message this way.
var ErrMsg = JsonConvert.DeserializeObject<dynamic>(response.Content.ReadAsStringAsync().Result);
