HI Diptyajit, Try below code. Hope this will help you. Add folowing references using System.Net.Http; using Newtonsoft.Json HttpClient client; string url = "http://111.93.203.157:8063" ; client = new HttpClient(); client.BaseAddress = new Uri(url); client.DefaultRequestHeaders.Accept.Clear(); client.DefaultRequestHeaders.Accept.Add( new MediaTypeWithQualityHeaderValue( "application/json" )); var response = client.GetAsync( string .Format( "/api/notification/eventnews" )).Result; if (response.IsSuccessStatusCode) { // Modify as per your requirement List emp = new List (); string responseString = response.Content.ReadAsStringAsync().Result; emp = JsonConvert.DeserializeObject >(responseString); // Your code goes here }
