Copy to Clipboard Print

Response response1 = request1.Send();
// Find a form in the response, and store it in a variable
List<Form> forms = response1.ExtractForms();

// This is a dynamic page, sometimes the login form is the second on the page
Form loginForm = null;
if (forms.Count == 2)
{
    loginForm = forms[1];
}
else
{
    loginForm = forms[0];
}

...

// Create a POST request that will send the modified loginForm back to the server
Request request2 = WebBrowser.CreateRequest(HttpMethod.POST, url2, 2);

// Fill in the form by specifying a username/password 
loginForm.GetInputElement("username").Value = "Bob Jones";
loginForm.GetInputElement("password").Value = "Pa55word";

// Attach the form to the request and send it to the server
request2.SetMessageBody(loginForm);
Response response2 = request2.Send();

Response response1 = request1.Send();
// Find a form in the response, and store it in a variable
List<Form> forms = response1.ExtractForms();

// This is a dynamic page, sometimes the login form is the second on the page
Form loginForm = null;
if (forms.Count == 2)
{
    loginForm = forms[1];
}
else
{
    loginForm = forms[0];
}
