Question

我是xamarin和Rest API的新手。

我正在尝试从Xamrine IOS代码中调用Rest API，如下所示。我的moto是获取列表（从API）并在列表视图（设备）中显示。但这给了我错误“错误的请求”。但是当在POSTMAN中放置相同的URL时，会给我适当的响应。请在这里帮助我。

URL：http://localhost/MobileAppAPI/

客户代码：

 static List<AuditModel> _audits = new List<AuditModel>();
        public static string GetAudits()
        {
            string URL = "http://localhost/MobileAppAPI/api/Values/Get?id=1000";
            string data = CreateObject(URL);
            return APIHelper.APIHelper.CreateObject(URL);
        }
        public static string CreateObject(string URL)
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(URL);
            request.Method = "GET";
            request.ContentType = "application/json";
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;

            try
            {
                using (Stream webStream = request.GetRequestStream())            
            using (StreamWriter requestWriter = new StreamWriter(webStream, System.Text.Encoding.ASCII))
            {
                requestWriter.Write("");
            }

                WebResponse webResponse = request.GetResponse();
                using (Stream webStream = webResponse.GetResponseStream())
                {
                    if (webStream != null)
                    {
                        using (StreamReader responseReader = new StreamReader(webStream))
                        {
                            string response = responseReader.ReadToEnd();
                            return response;
                        }
                    }
                }
            }
            catch (Exception e)
            {
                Console.Out.WriteLine("-----------------");
                Console.Out.WriteLine(e.Message);
                return e.Message;
            }
            return "";
        }

API代码：

 // GET api/values/5
        public string Get(int id)
        {
            return "value";
        }

例外：

Unhandled Exception:

System.Net.WebException: Error: ConnectFailure (Connection refused)
