I need to implement an application to post request to a given url and get response.
What are the best methods to post request to a given url and get response?
Please help.

If you call the GetRequestStream method, you must use the GetResponse method to retrieve the response. If a WebException is thrown, use the Response and Status properties of the exception to determine the response from the server.
The GetResponse method sends a request to an Internet resource and returns a WebResponse instance. If the request has already been initiated by a call to GetRequestStream, the GetResponse method completes the request and returns any response. The GetResponse method provides synchronous access to the WebResponse.
In a nutshell, WebRequest—in its HTTP-specific implementation, HttpWebRequest—represents the original way to consume HTTP requests in . NET Framework. WebClient provides a simple but limited wrapper around HttpWebRequest. And HttpClient is the new and improved way of doing HTTP requests and posts, having arrived with .
SerializeObject(parameterObj); HttpWebRequest request = (HttpWebRequest)WebRequest. Create(serviceUrl); request. ContentType = "application/json; charset=utf-8"; request. Method = "POST"; using (var streamWriter = new StreamWriter(request.
How about this?
using System; using System.IO; using System.Net; using System.Text; namespace Examples.System.Net { public class WebRequestPostExample { public static void Main () { // Create a request using a URL that can receive a post. WebRequest request = WebRequest.Create ("http://www.contoso.com/PostAccepter.aspx "); // Set the Method property of the request to POST. request.Method = "POST"; // Create POST data and convert it to a byte array. string postData = "This is a test that posts this string to a Web server."; byte[] byteArray = Encoding.UTF8.GetBytes (postData); // Set the ContentType property of the WebRequest. request.ContentType = "application/x-www-form-urlencoded"; // Set the ContentLength property of the WebRequest. request.ContentLength = byteArray.Length; // Get the request stream. Stream dataStream = request.GetRequestStream (); // Write the data to the request stream. dataStream.Write (byteArray, 0, byteArray.Length); // Close the Stream object. dataStream.Close (); // Get the response. WebResponse response = request.GetResponse (); // Display the status. Console.WriteLine (((HttpWebResponse)response).StatusDescription); // Get the stream containing content returned by the server. dataStream = response.GetResponseStream (); // Open the stream using a StreamReader for easy access. StreamReader reader = new StreamReader (dataStream); // Read the content. string responseFromServer = reader.ReadToEnd (); // Display the content. Console.WriteLine (responseFromServer); // Clean up the streams. reader.Close (); dataStream.Close (); response.Close (); } } } It's taken from MSDN: MSDN on WebRequest
