Post Data

[sde]

all i want to do is send post variables to a php script from a c# windows app: can anyone tell me where i'm going wrong?

the php page i'm sending too looks for POST variables named 'username' and 'password'

if i hard code something on that php page, it does show up in my message box, however it is not recognizing anything in the post variable. ( the same as this.Request.Form[username] in asp.net )

WebRequest wrq;
WebResponse wrs;

string strPostVars = "action=auth&username="+this.txtUsername.Text+"&password="+this.txtPassword.Text;
			
wrq = WebRequest.Create("http://domain.com/authenticate/index.php");
wrq.Method="POST";

StreamWriter sw = new StreamWriter(wrq.GetRequestStream());

sw.Write(strPostVars);
sw.Close();

wrs = wrq.GetResponse();

StreamReader sr = new StreamReader(wrs.GetResponseStream());

MessageBox.Show(sr.ReadLine());
