Post Data To ASP.NET From WINFORM

[truedeity]

I've been tryna do this for a long time now.

 

this is the url i want to post at.

 

http://promalechoice.com/post/pro-male-choice-is-not-bad.aspx

 

///Create post information.

 

StringBuilder baseRequest = new StringBuilder();

 

baseRequest.Append("txtName634119556352311642");

baseRequest.Append("=");

baseRequest.Append(System.Web.HttpUtility.UrlEncode("hulk hogan"));

baseRequest.Append("&");

 

 

baseRequest.Append("ctl00$cphBody$CommentView1$txtEmail");

baseRequest.Append("=");

baseRequest.Append(System.Web.HttpUtility.UrlEncode("hulkmedia@gmail.com"));

baseRequest.Append("&");

 

baseRequest.Append("ctl00$cphBody$CommentView1$txtWebsite");

baseRequest.Append("=");

baseRequest.Append(System.Web.HttpUtility.UrlEncode("www.hulkmedia.net"));

baseRequest.Append("&");

 

baseRequest.Append("ctl00$cphBody$CommentView1$txtContent");

baseRequest.Append("=");

baseRequest.Append(System.Web.HttpUtility.UrlEncode("I really have nothing more to say than I love posting via a winforms application..."));

 

 

 

 

 

//Create request object.

 

 

Uri uri = new Uri(@"http://promalechoice.com/post/pro-male-choice-is-not-bad.aspx");

 

 

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);

 

 

request.Method = "POST";

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

 

request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

request.Headers.Add("Accept-Charset", "ISO-8859-1,utf-8;q=0.7,*;q=0.7");

request.Headers.Add("Accept-Language", "en-us,en;q=0.5");

request.UserAgent = "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729)";

 

string result = "";

 

 

request.CookieContainer = new CookieContainer();

string viewstate;

request.ContentLength = 0;

 

 

 

using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())

{

using (Stream responseStream = response.GetResponseStream())

{

using (StreamReader readStream = new StreamReader(responseStream, Encoding.UTF8))

{

result = readStream.ReadToEnd();

 

//now extract the viewstate from the url. according to what ive read if you want to post to a asp.net form you need to include the viewstate in the postdata.

viewstate = Regex.Match(result, "(?<=__VIEWSTATE\" value=\")(?<val>.*?)(?=\")").Groups["val"].Value.ToString();

 

baseRequest.Append("&");

baseRequest.Append("__VIEWSTATE");

baseRequest.Append("=");

baseRequest.Append(viewstate); //Should the viewstate have a urldecode, encode, or none?

 

 

using (Stream writeStream = request.GetRequestStream())

{

UTF8Encoding encoding = new UTF8Encoding();

byte[] bytes = encoding.GetBytes(baseRequest.ToString());

writeStream.Write(bytes, 0, bytes.Length);

writeStream.Flush();

 

 

}

 

 

 

 

}

}

}

 

 

 

right now its saying that i cant open the request more than once. however, i need to be able to get the __VIEWSTATE into the postdata.

 

perhaps i can set the timeout on the request object to 0?

 

someone guide me in the right direction i just wana create a post on an asp.net webfrom from a winform thats it. hopefully someone can create a working example using the url I provided...

 

thanks for anything you can provide.
