WebAPI: PostAsync with query string does not work - asp.net-web-api

Question

see my sample web api action which take one string type parameter.
[RoutePrefix("api/customer")]
public class CustomerController : ApiController
{
[HttpPost, Route("DeleteCustomer")]
public HttpResponseMessage DeleteProduct(string customerID)
{
HttpResponseMessage response = null;
Customer customer = repository.Get(customerID);
if (customer == null)
{
var message = string.Format("No customer found by the ID {0}", customerID);
HttpError err = new HttpError(message);
response = Request.CreateErrorResponse(HttpStatusCode.ExpectationFailed, err);
response.ReasonPhrase = message;
}
else
{
if(repository.Remove(customerID))
{
response = Request.CreateResponse<Customer>(HttpStatusCode.Created, customer);
response.ReasonPhrase = "Customer successfully deleted";
}
else
{
var message = string.Format("Due to some error customer not removed");
HttpError err = new HttpError(message);
response = Request.CreateErrorResponse(HttpStatusCode.ExpectationFailed, err);
response.ReasonPhrase = message;
}
}
return response;
}
}
and calling like this below way with http client but not working and giving error Not found
private void btnDelete_Click(object sender, EventArgs e)
{
var uri = new Uri(ConfigurationManager.AppSettings["baseAddress"] + "/api/customer/DeleteCustomer");
var content = new FormUrlEncodedContent(new[]
{
new KeyValuePair<string, string>("customerID", "CUS01")
});
try
{
using (var client = new HttpClient())
{
using (var response = client.PostAsync(uri, content).Result)
{
if (response.IsSuccessStatusCode)
{
MessageBox.Show(response.ReasonPhrase);
}
else
{
Console.WriteLine("{0} ({1})", (int)response.StatusCode, response.ReasonPhrase);
var dict = JsonConvert.DeserializeObject<Dictionary<string, string>>(response.Content.ReadAsStringAsync().Result);
MessageBox.Show(dict["Message"]);
}
}
}
}
catch (HttpRequestException ex)
{
// catch any exception here
}
}
some one please see my code and tell me where i made the mistake in calling code ? thanks

[RoutePrefix("api/customer")]
public class CustomerController : ApiController
{
[HttpPost, Route("DeleteCustomer")]
public HttpResponseMessage DeleteProduct([FromBody]string customerID)
{
HttpResponseMessage response = null;
Customer customer = repository.Get(customerID);
if (customer == null)
{
var message = string.Format("No customer found by the ID {0}", customerID);
HttpError err = new HttpError(message);
response = Request.CreateErrorResponse(HttpStatusCode.ExpectationFailed, err);
response.ReasonPhrase = message;
}
else
{
if(repository.Remove(customerID))
{
response = Request.CreateResponse<Customer>(HttpStatusCode.Created, customer);
response.ReasonPhrase = "Customer successfully deleted";
}
else
{
var message = string.Format("Due to some error customer not removed");
HttpError err = new HttpError(message);
response = Request.CreateErrorResponse(HttpStatusCode.ExpectationFailed, err);
response.ReasonPhrase = message;
}
}
return response;
}
}
Could you add [FromBody] keyword in method parameter ?
