Posting Special charectors using HttpWebRequest

Kiran Suthar

Hi, I am using HttpWebequest. When i post text/HTML containing special charectors like "#" , post is successfully done. Can anybody help me? I am using following code, string strURL = "some text with special charectors"; HttpWebRequest HWReq = (HttpWebRequest)WebRequest.Create(strURL); HWReq.Timeout = (int)cbTimeout.SelectedItem * 1000; HWReq.UserAgent = "Mozilla/4.0 (compatible;MSIE 6.0b;Windows NT 5.0)"; HWReq.AllowAutoRedirect = true; HWReq.Method = "POST"; HWReq.ContentType = "application/x-www-form-urlencoded"; HWReq.CookieContainer = new CookieContainer(); HWReq.CookieContainer.Add(ccLogin1); HttpWebResponse HWResp = (HttpWebResponse)HWReq.GetResponse(); I am getting Error in the above last line. Thanks, Kiran Suthar.

Hello, Thanks for the reply. I have tried your suggestion but unfortunately my problem didnt solved. I am getting System.Net.WebException, The renote server returned an error:(500) Internal server error. Actually I am posting contents of an HTML file, I have observed that contents of only first few lines(of HTML file) are posted. I have used content type as "application/x-www-form-urlencoded" as well as "text/html" but both has not worked. My code is as below, StreamReader srTemplate = new StreamReader(FilePath); string strTemplate = srTemplate.ReadToEnd(); string URL = "http://myurl..."; URL=Uri.EscapeUriString(URL); string strQueryString ="?Data1=" + strTemplate strQueryString = Uri.EscapeDataString(strQueryString); URL = URL +"?"+ strQueryString; HttpWebRequest HWReq = (HttpWebRequest)WebRequest.Create(URL); HWReq.Timeout = 20000; HWReq.UserAgent = "Mozilla/4.0 (compatible;MSIE 6.0b;Windows NT 5.0)"; HWReq.AllowAutoRedirect = true; HWReq.Method = "POST"; HWReq.ContentType = "application/x-www-form-urlencoded"; HWReq.CookieContainer = new CookieContainer(); HWReq.CookieContainer.Add(ccLogin); HttpWebResponse HWResp = (HttpWebResponse)HWReq.GetResponse(); Error occurs at the above last line. Any suggestion? Thanks, Kiran Suthar.

What exception message you get? You should always post the exception message, because we can't tell what the problem is without it.

If i understood right, you want a URI to have special character in it, like in GET message? For example http://www.someaddress.com/index.htm?variable=Specialchars##HERE#¤%

URI itself cannot contain special characters, but you can put special characters in get message if you convert the address this way:

string uri = "http://www.someuri.com/index.htm"; string getData = "parameter=VALUE#####"; uri= Uri.EscapeUriString(uri); getData = Uri.EscapeDataString(getData); uri = uri + "?" + getData;

That converts URI to its escaped representation, and thus strURI is in legal URI format.
