Sanırım birçok arkadaşımızın ihtiyacı olacak bir bilgidir. Hatta Eylül arkadaşımız şurada sormuş, cevap vermeyi atlamışım:

        string result = string.Empty;
        HttpWebRequest m_WebRequest;
        HttpWebResponse m_WebResponse;
        Encoding m_Encoding;
        byte[] m_PostData;
        Stream m_WriteStream;
        Stream m_ResponseStream;
        StreamReader m_StreamReader;

        m_Encoding = Encoding.GetEncoding(”iso-8859-9″);
        m_PostData = m_Encoding.GetBytes(”ığüşiöç”);

        m_WebRequest = HttpWebRequest.Create(”http://sunali.com“) as HttpWebRequest;
        m_WebRequest.Method = “POST”;
        m_WebRequest.ContentLength = m_PostData.Length;
        m_WebRequest.ContentType = “application/x-www-form-urlencoded”;

        try
        {
            m_WriteStream = m_WebRequest.GetRequestStream();
        }
        catch (System.Net.WebException)
        {
            throw;
        }

        m_WriteStream.Write(m_PostData, 0, m_PostData.Length);
        m_WriteStream.Close();
        m_WriteStream.Dispose();

        m_WebResponse = m_WebRequest.GetResponse() as HttpWebResponse;

        m_ResponseStream = m_WebResponse.GetResponseStream();

        m_StreamReader = new StreamReader(m_ResponseStream, m_Encoding);

        result = m_StreamReader.ReadToEnd();

        m_ResponseStream.Close();
        m_ResponseStream.Dispose();
        m_WebResponse.Close();
        m_WebRequest.Abort();

        Response.Write(result);
