[Rama Jayapal]

hi

i have to develop a webapplication where i need to request a webpage with the help of

httpwebrequest and httpwebresponse class.like the following code

webRequest = HttpWebRequest.Create(http://URL) as HttpWebRequest;

cookies = new CookieContainer();

webRequest.Method = "GET";

webRequest.CookieContainer = cookies;

webResponse = webRequest.GetResponse() as HttpWebResponse;

reader = new StreamReader(webResponse.GetResponseStream());



now what i need to do is perform signup programmatically

we can do this by postdata


string postdata="username=sally&password=YYYYY";

but i need to know how can we postdata if the value is going to be a select tag

for example if the website has a column of select tag like

<select name=location>

<option value=1>Agra</option>

<option value=2>bangalore</option>

</select>

how can we give this value in postdata

any idea about this plz help
