[TestClass]
    public class Tests
    {
        private string getUrl = "https://reqres.in/api/users?page=2";
        [Test]
        public void TestMethod1()
        {

            // step 1. To  create http client 
            HttpClient httpClient = new HttpClient();

            //step for create the request and execute the request 
            Task<HttpResponseMessage> responseMessage = httpClient.GetAsync(getUrl);
            HttpResponseMessage httpResponseMessage = responseMessage.Result;
            Console.WriteLine(httpResponseMessage.ToString());

            //for printing the statusCode
            HttpStatusCode httpStatusCode = httpResponseMessage.StatusCode;
            Console.WriteLine("StatusCode=>{0}", httpStatusCode);
            Console.WriteLine("StatusCode=>{0}", (int)httpStatusCode);

            //for printing the content
            HttpContent httpContent = httpResponseMessage.Content;
            Task<string> ResponseContentData = httpContent.ReadAsStringAsync();
            string responseData = ResponseContentData.Result;

            Console.WriteLine(responseData);
            // step for closing the connection
            httpClient.Dispose();

        }
