Help with a sending of a image via HTTP

[sergiotb]

Hello everyone!! I'm trying to send a image (jpg) from a C# program to a CGI perl. The problem is that the code of the client C# is not working properly...I guess. The steps to send the image are: 1) I get the array of bytes from the image 2)Convert the array to string. 3) Send the string via http to the cgi in Perl. My question is, is this code working good? I don't know if the encode method is the correct. Please, Help me !
the real problem is the CGI doesn't receive the total number of bytes from the image but lower number, so I can save an image in the server but it can't be seen because is incomplete . I think the problem is in this method....

This is the method which I use to send the request and to receive the answer,

public String enviarImagen(String chorro)
        {
            String parametro = "imagen=" + chorro;
            System.Net.HttpWebRequest cliente = (HttpWebRequest)WebRequest.Create("http://localhost/cgi-bin/subirImagen.pl");
            cliente.Method = "POST";
 
            byte[] bytesparametros = Encoding.ASCII.GetBytes(parametro);
            Stream os = null;
            try
            { // send the Post
 
                cliente.ContentLength = bytesparametros.Length;   //Count bytes to send
                os = cliente.GetRequestStream();
            //Send it
                os.Write(bytesparametros, 0, bytesparametros.Length);
 
            }
            catch (WebException ex)
            {
                MessageBox.Show(ex.Message, "HttpPost: Request error",
                   MessageBoxButtons.OK, MessageBoxIcon.Error);
            }
            finally
            {
                if (os != null)
                {
                    os.Close();
                }
            }
 
            try
            {
                System.Net.WebResponse respuesta = cliente.GetResponse();
                StreamReader mensaje = new StreamReader(respuesta.GetResponseStream());
                String resultado = mensaje.ReadToEnd();
                mensaje.Close();
                return resultado;
            }
 
            catch (WebException e)
            {
                WebExceptionStatus status = e.Status;
                if (status == WebExceptionStatus.ProtocolError)
                {
                    MessageBox.Show("The server returned protocol error ");
                    // Get HttpWebResponse so that you can check the HTTP status code.
                    HttpWebResponse httpResponse = (HttpWebResponse)e.Response;
                    MessageBox.Show((int)httpResponse.StatusCode + " - "
                       + httpResponse.StatusCode);
                }
                return e.Status.ToString();
            }
            catch (Exception ex)
            {
                return ex.ToString();
            }
 
        }

Welcome to the site. Have you got your application working yet? I suggest that if you haven't, debug until you get one part working and then go from there.
