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
}
