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 }
