Simulate Form Post with HttpRequest

string postData = "Email=test@email.be";

System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
byte[] data = encoding.GetBytes(postData);

System.Net.HttpWebRequest request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create("http://www.posturl.com");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;

System.IO.Stream newStream = request.GetRequestStream();
newStream.Write(data, 0, data.Length);
newStream.Close();
