Well I am trying to log in to a form authentication page.

ok i successfuly loged in and it work.

Now the problem is i can not send the second request to that page to click on a link in logged in page.

 

 Do i need to create another reuqest for it or can i use the old one?

here is the error i get:

Cannot send a content-body with this verb-type. 

 here is my code.

 

private void button2_Click(object sender, RoutedEventArgs e)

{

string loginurl = "http://localhost/login.aspx";

HttpWebRequest myreq = (HttpWebRequest)WebRequest.Create(loginurl);

string postData = "some data for login in";

string ClickButton = "click the button on logged in page";

CookieContainer cookie = new CookieContainer();

myreq.CookieContainer = cookie;

myreq.ContentType = "application/x-www-form-urlencoded";

myreq.Method = WebRequestMethods.Http.Post;

 

// Send the login information to server

byte[] bytearray = Encoding.UTF8.GetBytes(postData);Stream datastream = myreq.GetRequestStream();

datastream.Write(bytearray, 0, bytearray.Length);

datastream.Close();

 

// Send the order to click a button on logged in page

byte[] bytearray1 = Encoding.UTF8.GetBytes(ClickButton);Stream datastream1 = myreq.GetRequestStream();

datastream1.Write(bytearray1, 0, bytearray1.Length);

datastream1.Close();

HttpWebResponse wr = (HttpWebResponse)myreq.GetResponse();

}

I'm confused by what your trying to do here. Are you trying to postback to the login page and force a redirect?

If so you should just do a Server.Transfer.

Also your comment "send login information to the server"

Your already at the server so what are you trying to do here exactly?

Hi Evan,

let me put it that way. I want to log in to a web site using my windows form app. then click on a button after loging in.

here is the code for loging in.

private void button2_Click(object sender, RoutedEventArgs e)

{

string loginurl = "http://localhost/login.aspx";

HttpWebRequest myreq = (HttpWebRequest)WebRequest.Create(loginurl);

 

string postData = "__EVENTTARGET=&__EVENTARGUMENT=&__VIEWSTATE=%2FwEPDwUKMT3D&Login2%24UserName=test&Login2%24Password=test&Login2%24LoginButton=Log+In&__EVENTVALIDATION=%2FwEWBmbqq";

 

CookieContainer cookie = new CookieContainer();

myreq.CookieContainer = cookie;

myreq.ContentType = "application/x-www-form-urlencoded";

myreq.Method = WebRequestMethods.Http.Post;

 

byte[] bytearray = Encoding.UTF8.GetBytes(postData);Stream datastream = myreq.GetRequestStream();

datastream.Write(bytearray, 0, bytearray.Length);

datastream.Close();

HttpWebResponse wr = (HttpWebResponse)myreq.GetResponse();

}
