There are situations where you want to post data to remote server and other external URL.
We can do this using System.Net namespace.
In this sample example we have this "http://www.dummydomain.com/pagename.aspx" URL and we want to post query string data like "pageid=1&search=.net" and capture response of this in our code.
We are using HttpWebRequest and HttpWebResponse class for this.
C# Example :

C# Example :
Uri url = new Uri("http://www.dummydomain.com/pagename.aspx"); string strParameter = "pageid=1&search=.net"; string data = string.Format("{0}", strParameter); if (url.Scheme == Uri.UriSchemeHttp) { //Create Request for given url System.Net.HttpWebRequest objRequest =(System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(url); //Set Request Method objRequest.Method = System.Net.WebRequestMethods.Http.Post; objRequest.ContentLength = data.Length; objRequest.ContentType = "application/x-www-form-urlencoded"; //Write request stream System.IO.StreamWriter objWriter = new System.IO.StreamWriter(objRequest.GetRequestStream()); objWriter.Write(data); objWriter.Close(); //Get Response from url System.Net.HttpWebResponse objResponse = (System.Net.HttpWebResponse)objRequest.GetResponse(); //Read Response System.IO.StreamReader objReader = new System.IO.StreamReader(objResponse.GetResponseStream()); string result = objReader.ReadToEnd(); objResponse.Close(); pnlScreen.GroupingText = result; }
VB.net Example :
Dim url As New Uri("http://www.dummydomain.com/pagename.aspx") Dim strParameter As String = "pageid=1&search=.net" Dim data As String = String.Format("{0}", strParameter) If url.Scheme = Uri.UriSchemeHttp Then 'Create Request for given url Dim objRequest As System.Net.HttpWebRequest = DirectCast(System.Net.HttpWebRequest.Create(url), System.Net.HttpWebRequest) 'Set Request Method objRequest.Method = System.Net.WebRequestMethods.Http.Post objRequest.ContentLength = data.Length objRequest.ContentType = "application/x-www-form-urlencoded" 'Write request stream Dim objWriter As New System.IO.StreamWriter(objRequest.GetRequestStream()) objWriter.Write(data) objWriter.Close() 'Get Response from url Dim objResponse As System.Net.HttpWebResponse = DirectCast(objRequest.GetResponse(), System.Net.HttpWebResponse) 'Read Response Dim objReader As New System.IO.StreamReader(objResponse.GetResponseStream()) Dim result As String = objReader.ReadToEnd() objResponse.Close() pnlScreen.GroupingText = result End If
