Get value to byte() [modified]

[hung_ngole]

Hi, I have the following code, how can I get the value of the stream into byte array (the response contains binary data and using the readToEnd() fails) HttpWebResponse response = request.GetResponse() System.IO.Stream responseStream = response.GetResponseStream() Thanks in advance, Hung.

Hello Try this:

HttpWebResponse response = request.GetResponse()
System.IO.Stream responseStream = response.GetResponseStream()
byte[] input = new byte[responseStream.Length];
responseStream.Read(input, 0, (int)responseStream.Length - 1);

Although the stream has data, the length of responseStream is -1. This is the main problem I facing !! Thanks anyway! Hung. Hung

I have the problem with binary data (Ex: image) not the textual data! Thanks anyway, Hung. Hung

According to the MSDN[^] documentation, Read returns the number of bytes actually read. So you could always create a buffer of some arbitrary size, say 512 bytes, and then loop till Read returns less than 512 bytes. Something like.

ArrayList finalBuffer = new ArrayList();
byte []buffer = new byte[512];

int bytesRead = 0;
while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) != 0)
{
   for (int i = 0; i<bytesRead; ++i)
   {
       finalBuffer.Add(buffer[i]);
   }
}

You are right. Sorry. This is what you need to do: // Prepare web request... HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create("http://www.noviway.com"); // We use POST ( we can also use GET ) myRequest.Method = "GET"; // Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable. HttpWebResponse myHttpWebResponse= (HttpWebResponse)myRequest.GetResponse(); // Display the contents of the page to the console. Stream streamResponse = myHttpWebResponse.GetResponseStream(); MemoryStream memStream = new MemoryStream(); byte[] readBuffer = new byte[256]; // Read from buffer int count = streamResponse.Read( readBuffer, 0, 256 ); while (count > 0) { memStream.Write(readBuffer, 0, count); // Read from buffer count = streamResponse.Read( readBuffer, 0, 256); } byte[] originalBuffer = memStream.ToArray(); // Release the response object resources. streamResponse.Close(); // Close response myHttpWebResponse.Close(); Eran Aharonovich (eran.aharonovich@gmail.com ) Noviway
