Bytes to be written to the stream exceed the Content-Length bytes size specified.

Hi.. I'm trying to upload a image file to the server using HttpWebRequest/HttpWebResponse. so i form a Postdata as and storing in a StringBuilder object (sbFormData)..

Content-Type: multipart/form-data; boundary=AaB03x

   --AaB03x
   Content-Disposition: form-data; name="submit-name"

   Larry
   --AaB03x
   Content-Disposition: form-data; name="files"
   Content-Type: multipart/mixed; boundary=BbC04y

   --BbC04y
   Content-Disposition: file; filename="file1.txt"
   Content-Type: text/plain

   ... contents of file1.txt ...
   --BbC04y
   Content-Disposition: file; filename="file2.gif"
   Content-Type: image/gif
   Content-Transfer-Encoding: binary

   ...contents of file2.gif...
   --BbC04y--
   --AaB03x--

while adding the image content i read byte by byte and then adding to the sbFormData. But when i see the sbFormdata's length its not showing exact length. That is not adding the image content's length. Then setting the HttpWebRequest.Length to sbFormdata.Length.. httpWebRequest.ContentLength = sbFormData.Length; after when i try to write the sbFormData to the httpWebRequest.GetRequestStream(), i get Error: "Bytes to be written to the stream exceed the Content-Length bytes size specified."

try
{
  StreamWriter s = new StreamWriter(httpWebRequest.GetRequestStream());
  s.Write(sbFormData.ToString());        
  s.Close();
}
catch (Exception e)
{
  Debug.Print("Error in sending data " + e.Message);
}

Please help me.. regards, nas

You are setting the content length to the number of characters in the string, but that is not the same as the number of bytes that the string uses when encoded. You have to encode the string first to get the size of the encoded data.
