Calling a web service URL in console application ASP.NET C# or WEB API

These are the three methods we can use for calling web service:-

static void Main(string[] args)

        {         

            string url = string.Format("http://localhost:85/WebService.asmx/HelloWorld?id=1&id1=8");

            //HttpClient

            using (var client = new WebClient())

            {

                client.Headers.Add("Content-Type:application/xml");

                client.Headers.Add("Accept:application/xml");

                var result = client.DownloadString(url);

                Console.WriteLine(Environment.NewLine + result);

            }

}

--------------------------------******************-------------------------

static void Main(string[] args)

        {         

            string url = string.Format("http://localhost:85/WebService.asmx/HelloWorld?id=1&id1=8");

          WebRequest request = HttpWebRequest.Create(url);

            

            using (WebResponse response = request.GetResponse())

            {

                using (StreamReader reader = new StreamReader(response.GetResponseStream()))

                {

                    string urlText = reader.ReadToEnd();

                    //Do whatever you need to do

                    Console.WriteLine(urlText);

                }

            }

}

-------------------------------******************----------------------------

static void Main(string[] args)

        {         

            string url = string.Format("http://localhost:85/WebService.asmx/HelloWorld?id=1&id1=8");

         HttpWebRequest request1 = WebRequest.Create(url) as HttpWebRequest;

            //request.Accept = "application/xrds+xml";  

            HttpWebResponse response1 = (HttpWebResponse)request1.GetResponse();

            WebHeaderCollection header = response1.Headers;

            var encoding = ASCIIEncoding.ASCII;

            using (var reader = new System.IO.StreamReader(response1.GetResponseStream(), encoding))

            {

                string responseText = reader.ReadToEnd();

                Console.WriteLine(responseText);

            }

}

-------------------**********************------------------------------------

but I will prefer (best method)

static void Main(string[] args)

        {         

            string url = string.Format("http://localhost:85/WebService.asmx/HelloWorld?id=1&id1=8");

        // demo data from website

        //string url = string.Format("https://reqres.in/api/users?page=2");

          WebRequest request = HttpWebRequest.Create(url);

            

            using (WebResponse response = request.GetResponse())

            {

                using (StreamReader reader = new StreamReader(response.GetResponseStream()))

                {

                    string urlText = reader.ReadToEnd();

                    //Do whatever you need to do

                    Console.WriteLine(urlText);

                }

            }

}
