Hello,

I am writing a method that performs a HTTP POST and sends two text
parameters and the third is an image that will be uploaded as part of the
HTTP POST.  I can get the function to properly post the text parameters, but
the image shows up as an "X" like it is missing.  It's not missing from the
path, I just believe that there is something wrong with the encoding or how
I am creating the boundary package.  Here is the method; any help would be
appreciated.

  protected string ExecutePostCommand(string filename, byte[] photo, string
text, string place)
   {
       HttpWebRequest request =
(HttpWebRequest)HttpWebRequest.Create(@"http://testdomain.com/api/post");
       request.PreAuthenticate = true;
       request.AllowWriteStreamBuffering = true;

       string boundary = System.Guid.NewGuid().ToString();

       if (!string.IsNullOrEmpty(Username) &&
!string.IsNullOrEmpty(Password))
       {
           request.Credentials = new NetworkCredential(Username, Password);
           request.ContentType = string.Format("multipart/form-data;
boundary={0}", boundary);
           request.Method = "POST";

           // Build Contents for Post
           string header = string.Format("--{0}", boundary);
           string footer = header + "--";

           StringBuilder contents = new StringBuilder();

           // Image
           contents.AppendLine(header);
           contents.AppendLine(string.Format("Content-Disposition:
form-data; name=\"image\"; filename=\"{0}\"", filename));
           contents.AppendLine("Content-Type: image/jpeg");
           contents.AppendLine();
           contents.AppendLine(Encoding.UTF8.GetString(photo));
           // Text
           contents.AppendLine(header);
           contents.AppendLine("Content-Disposition: form-data;
name=\"text\"");
           contents.AppendLine();
           contents.AppendLine(text);
           // Place
           contents.AppendLine(header);
           contents.AppendLine("Content-Disposition: form-data;
name=\"place\"");
           contents.AppendLine();
           contents.AppendLine(place);
           // Footer
           contents.AppendLine(footer);

           // This is sent to the Post
           byte[] bytes = Encoding.UTF8.GetBytes(contents.ToString());

           request.ContentLength = bytes.Length;

           using (Stream requestStream = request.GetRequestStream())
           {
               requestStream.Write(bytes, 0, bytes.Length);
               requestStream.Flush();
               requestStream.Close();

               using (WebResponse response = request.GetResponse())
               {
                   using (StreamReader reader = new
StreamReader(response.GetResponseStream()))
                   {
                       return reader.ReadToEnd();
                   }
               }
           }
       }

       return null;
   }
