Im new to C# and Rest Api. Please help me, I read many answers but none of them are working. Please help me thank you.

Answer 1

I would recommend you to have a look at the high-level WebClient -class instead. You must still pay close attention to the exception message.

        var serviceRequest = new WebClient();
        string response = serviceRequest.DownloadString(new Uri(url));

Answer 2

You can use this code.

            using (var client = new HttpClient())
            {
                client.BaseAddress = new Uri("http://192.168.150.1:8090/");
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

                HttpResponseMessage response = client.GetAsync("api/storeLayout/kinectToRacks/42").Result;
                if (response.IsSuccessStatusCode)
                {
                    var str = response.Content.ReadAsStringAsync();
                }
            }
