using System.IO;

stringPostData ="Username="+ login_ user name. Text +"&password="+ login_ password. Text;//Post parameters and values written in Postdate
byte[] ByteArray =Encoding. Default.getbytes (PostData);
stringURL =" http://127.0.0.1/user.php";//post to website
HttpWebRequestWebRequest = (HttpWebRequest)WebRequest. Create (New Uri(URL));
Webrequest.method =the POST";
Webrequest.contenttype ="Application/x-www-form-urlencoded";
Webrequest.contentlength = Bytearray.length;
StreamNewstream = Webrequest.getrequeststream ();
Newstream.write (ByteArray, 0, bytearray.length);
Newstream.close ();

Receive return information:

HttpWebResponse response = (httpwebresponse) webrequest.getresponse ();
StreamReader php = new StreamReader(response. GetResponseStream (), Encoding. Default);
